Workstation Cranes

Adding cranes to workstations is an excellent way to increase theproductivity and flexibility of workers and their equipment. Workstationcranes greatly increase workers’ ability to lift, move and manipulateequipment and raw materials.
One of the best kinds of crane to add to a workstation is amanipulator crane. This is a device that enables a worker to move apiece of equipment or material to any position that is needed. Forexample: a worker in a furniture factory could use a manipulator craneto turn a table over in order to apply varnish to it.
Using workstation cranes can reduce workplace injuries becauseworkers will no longer have to pickup or carry heavy objects. Insteadthey can move the objects using the crane which reduces liabilities.Workers can be on the production line doing their jobs instead ofsitting home nursing bad backs and collecting disability payments.

Workstation cranes often come in the form of overhead bridge cranes and in addition to reducing liability and injuries, installingworkstation cranes can also increase speed and productivity. Workerswill not have to interrupt their work to pick up or carry items insteadthey can use the crane to move the objects.
Nor will workers have to interrupt their routine to get forkliftsand other equipment to lift a heavy load. They can simply use the cranewhich will save time and make the work environment safer. The risk ofinjuries from forklift accidents can be limited or even eliminated byusing workstation cranes.
The use of automated or robotic workstation cranes can make the workenvironment even more productive. The need for special crane operatorscan be eliminated because every worker can be his own crane operator.

The capabilities of workstation cranes can be extended by mountingaccessories such as tools upon them. Paint guns, cutting equipment andother devices can be mounted upon overhead cranes and lowered into placewhen the worker needs them.
This can limit the need for storage and increase production becauseworkers won’t have to leave their workstations to get tools and otherequipment for a job. Nor will a worker need to cease production in orderto return a tool to the storage area.
Almost any tool that workers need can be mounted on an overheadcrane and lowered into place. Using a system of trolleys can enableseveral workers to share overhead tools and reduce costs further.

Types of Workstation Cranes

The most common workstation cranes are overhead cranes such as chainhoists and rope wire hoists. These are simply mounted over theworkstation and operated with a remote control device by the worker.
The usual use of these devices is to lift objects that the work isworking upon into place. A way to reduce costs is to mount an overheadcrane on a trolley that moves back and forth over the floor. This canenable several workers to use the same crane and reduce costs.
In some cases jib and gantry cranes can be used as workstationcranes in facilities with high ceilings or outdoor work areas jib cranesare easy to install and use. One advantage to the use of jib and gantrycranes is that they can be mounted on wheels or tracks and moved arounda facility. This can limit the number of cranes required.

Underhung Crane

就爱看电影网An underhung crane or under-running crane is simply a crane that sitson the underside of a beam that is usually hung from the roof of abuilding. When these cranes run on one beam they are also calledmonorail cranes, when they hang from two beams these cranes can becalled runway cranes.

The majority of underhung cranes are limited to capacities of lessthan 10 tons. The carrying capacity of these cranes is usually limitedto the strength of the roof. Additional supporting beams can be added toincrease the load capacity of an underhung crane.

The reason cranes are hung under beams is to safe space in smalleror older facilities. Installing an underhung crane can enable anorganization to install an overhead crane system without majorrenovation to an existing facility. This can obviously help anorganization limit costs when ordering an overhead crane.

Monorail Underhung Crane

Monorail or single beam cranes are one of the most common types ofoverhead cranes because they are among the cheapest overhead cranesavailable. The monorail underhung crane is cheaper because it onlyrequires one beam to operate on.

A big advantage to monorail cranes is that can move up and down thebeam on a motorized trolley. Installing a monorail crane can provide anorganization with a moving overhead crane at a fraction of the price of arunway or gantry crane.

Monorail underhung cranes are ideal for older, smaller facilitiessuch as machine shops, garages and factories. They can provide a cranethat can move objects such as engines around the shop without taking up alot of space.

The major reason to install a monorail underhung crane is to savespace on the floor without doing major construction. Another advantageto using a monorail crane is that the shop won’t have to be shut downfor construction while it is being installed.

Double Girder Underhung Crane (Runway Crane)

The major difference between a monorail and a double girderunderhung crane is that the double girder crane has a much higher loadcapacity. The double girder crane has a higher capacity because it issupported by two girders rather than one girder.

The double girder crane will be more expensive to install and itusually requires more installation work. This means that a shop may haveto be shut down while a runway crane is being installed. Organizationscan sometimes save money on this construction by doing the installationthemselves or having their workforce help the crane company with theinstallation.

A big advantage to using a double girder crane is that load capacitycan be increased by adding supports. This will require moreconstruction and cost but it can significantly increase load capacity.In some cases a gantry crane can be cheaper and more versatile than arunway crane.

The double girder underhung crane is ideal for use in largerfacilities such as diesel garages, factories and waste water treatmentplants. Any facility that needs to lift and move large loads indoorscould benefit from a double girder underhung crane.

Overhead Crane Service and Repairs

Organizations often loose time and money whenever an overhead craneis broken down or not operating correctly. This means that havingoverhead crane service and repairs done correctly the first time isvital to an organization’s success.

If an organization operates an overhead crane it will need to haveoverhead crane service and repairs done on a regular basis. Mostoverhead cranes will have to be serviced that is cleaned, lubricated,adjusted and checked for problems on a regular basis at least once ayear.

Not having this preventive maintenance done can lead to breakdownsand other problems. Preventive maintenance may also be required by stateor local law and liability insurance policies. Even if it is notrequired having an overhead crane serviced on the basis recommended bythe manufacturer is always a good idea.

Required Overhead Crane Service and Repairs

In addition to regular preventive maintenance, an overhead crane may also have to be tested for compliance with OSHA(Occupational Safety and Health Administration) standards and loadtested every year. In some areas this is required by law, in other casesit could be required by liability insurance policies.

Compliance and load testing will have to be performed by a certifiedcrane technician. It should be possible for an organization to savemoney by having the preventive maintenance and the compliance testingdone at the same time.

Most crane companies offer packages where a technician comes out anddoes the maintenance and the tests. This can save a company and help itcomply with the law and insurance requirements. The crane companyshould know what the legal requirements for testing are in your area.

Emergency Overhead Crane Service and Repairs
Any organization that relies on an overhead crane will also requireemergency overhead crane service and repairs. If the crane breaks downor starts malfunctioning an entire shop or production could be forced toshut down.

This means that an organization should always work with a companythat can send out a technician for overhead crane service and repairsvery quickly. In most cases the technician should be on site and workingon the crane within a few hours.

It is usually best to use the company that does the preventivemaintenance and compliance for emergency repairs. This company’stechnicians will be familiar with your crane and should be able to fixit faster. They should also have the required parts available.

Service Policies for Overhead Crane Service and Repairs

One of the best courses of action for a company that relies upon anoverhead crane is to get a service policy for overhead crane service andrepairs. Most crane companies will offer these policies at a veryreasonable rate.

Newer cranes should come with such a policy when they are purchased.Service policies that cover overhead crane service and repairs forolder cranes can also be purchased. Purchasing such a policy can help anorganization avoid losing time and money because of a malfunctioningcrane.

Gantry Hoists

Gantry hoists are placed in the middle of gantry cranes to providethe lifting power for those devices. A gantry crane is a lifting devicethat consists of a large metal structure called a gantry.

Generally a gantry crane is a much larger and heavier lifting devicethan a bridge crane although it works on the same principal. The majordifference between a gantry and a bridge crane is that a bridge crane isusually attached to an existing structure such as a building while agantry crane sits on a free standing structure of its own.

Gantry cranes and gantry hoists are often very large and powerful. Atypical gantry crane can be 150 feet in length and move up to 150 tons.Unlike bridge cranes, gantry cranes are often used out doors.

Advantages to Gantry Hoists

The big advantage to gantry cranes is that they are generally mobilestructures they can be moved on wheels, tires, rails or even crawlertracks. Many gantry cranes used in construction and transportation aremounted on wheels or tracks so they can be moved around a facility.

This means that gantry cranes can be used in locations where normalbridge cranes can not be used. It also means that they can be used forcontinuous heavy lifting jobs outside a building or in a large outdoorarea such as a port.

Gantry cranes are generally considered to be cheaper to build thanbridge cranes. A big advantage to gantry cranes is that they can bemoved or broken down for storage when not needed. Gantry cranes can alsoeasily be broken down for transporation.

The most powerful gantry hoists are those used to move cargocontainers in locations such as rail yards and ports. Gantry hoists arecommonly used to load containers onto trains and trucks.

Gantry Hoists and Gantries

The gantry hoist is the device that makes a gantry crane possible.It is generally a very powerful wire rope hoist placed in the center ofthe gantry to provide the lifting power.

Many gantry hoists are the same devices used in large bridge andportal cranes. The principal is the same except that the structure isgenerally free standing. As with bridge cranes, a gantry hoist can be atraveling mechanism so that it can move back and forth on the gantry.

Some of the most rugged gantry hoists are those used in the nuclearpower industry. Facilities that deal with nuclear material often usespecial gantry cranes mounted on crawler tracks or wheels. These selfpropelled vehicles use powerful gantry hoists to move nuclear materials.

One big advantage to gantry hoists is that they can be mounted onself propelled vehicles to provide specific kinds of lifting power. Thehoists used on self propelled vehicles are usually custom made for thatpurpose. Some of them may contain their own engine while others draw onelectric current generated by the vehicle.

In some cases gantry hoists can be placed indoors. Buildings withvery tall ceilings and structures not strong enough to support bridgecranes can necessitate the construction of a gantry indoors.

Crane Accessories

A good way for a company to save money is to use crane accessories toexpand the capacity and capabilities of its cranes.Instead of buyingexpensive pieces of new equipment, a company can simply add a fewaccessories to its cranes or crane system.

A firm could add crane forklifts to its crane instead of buying aseparate forklift. This would eliminate the need for buying a separatepiece of equipment. It would eliminate the fuel and maintenance costsfor the additional vehicle and possibly the labor costs for anadditional operator.

A company could use the piece of equipment it already has availableinstead of buying a new piece of equipment. This means that a crane canbe in use and making money for the company rather than gathering dust ina corner of the yard.

Crane Accessories for Overhead Cranes

Many people may not realize that crane parts and accessories can also be usedon the overhead cranes used in factories and other facilities. This caneliminate the need for additional equipment and machinery in thesefacilities.

A clamshell bucket could be added to a bridge or gantry crane foruse in moving powdered material such as cement to a machine. Suctioncups, grapplers and other accessories can be added to overhead cranes toturn them into manipulator cranes.

The use of accessories could enable workers to move pieces ofequipment or raw material they are working on into special positions. Aworker in a furniture factory could turn a table he is building upsidedown in order to put legs on it.

This could reduce the need for labor by worker and the potential ofinjury to workers. The use of ergonomic manipulators can reducerepetitive motion injuries and liability costs.

Specialized Crane Accessories

Another excellent use of overhead cranes is to hang tools and otheraccessories on them. This can reduce the need for storage space becausethe tools can be kept overhead.

Using specialized crane accessories can make the production processfaster and more efficient. Workers will not have to spend time fetchingtools from storage areas or returning them from a storage area.

Commonly used tools such as paint guns, and saws could be suspendedfrom cranes for use on the floor. Workers would simply have to hit aremote control when they needed to have a tool lowered to them and hitit again to lift the accessory out of their way when they no longerneeded it.

Other Crane Accessories

In the future automated and robotic crane accessories willincreasingly be used in factories and other facilities. Automatedequipment will be lowered into place when it is needed for a productionprocess and lifted away when it is no longer needed.

Cranes could even be used to move robots from one part of thefactory floor to another. This could save storage space and reduce theamount of machinery needed which would obviously reduce costs.

Every organization that makes use of cranes such look into the useof crane accessories. These accessories can extend the capability ofcranes and give organizations more return on the money they haveinvested in their cranes.

Chain Hoists

Many businesses will overlook the use of chain hoists to fill theiroverhead crane needs because chain hoists are simple and basic. Thesefirms should take another look because chain hoists are among thecheapest and most functional overhead cranes.

The big advantage to chain hoists is that often do not requireelaborate or complex methods of installation. In many cases a chainhoist can simply be hung in place over a workstation.

This means that such hoists can be quickly installed and movedaround the factory when needed. They can also be quickly taken down andstored away when they are not needed. This makes chain hoists perfectfor smaller factories and facilities like garages and machine shops thatdon’t need a full system of overhead cranes.

The Versatility of Chain Hoists
In facilities that have a crane system installed, a chain hoist can be agood way to move items without expanding the system. For example achain hoist could be used in a room where the crane system doesn’textend.

A chain hoist can also be used to lift one particular object so thecrane system doesn’t have to be tied up. The use of smaller chain hoistsis a low cost method to extend the reach of a crane system.

Electric chain hoists are among the most versatile and powerfulavailable. A modern electric chain hoist can lift comparable loads torope wire hoists without the cost. Such a hoist is often cheaper toinstall and can be operated by remote control.

Uses of Chain Hoists

In addition to eliminating the need for expensive crane systems,electric chain hoists can often take the place of expensive liftingsystems and forklifts. This can reduce costs because overhead hoistsware usually cheaper than such devices.

It can also save space in a facility because overhead hoists do nottake up space on the floor. This can reduce storage costs and eliminatethe need for additional equipment. It can also save time because workerswon’t have to go and get a forklift to lift something.

In smaller facilities where space is at a premium, chain hoists are aperfect method of meeting lifting needs. They are also ideal forsmaller businesses that may not be able to afford more expensivealternatives.

When Chain Hoists are Best

Chain hoists are best used to lift smaller loads in smallerfacilities such as garages and machine shops. They can also be usedeffectively in factories and larger facilities where a crane system maynot be cost effective.

As with wire rope hoists, chain hoists can be made to move ontrolleys. This enables the hoist to be used throughout the facility andeliminates the need for lifting machinery. A cost effective alternativeto a bridge crane is a chain hoist on a hand moved overhead trolley.

Motorized trolleys are also available for chain hoists. Thesedevices can enable a chain hoist to be used as an overhead crane withoutthe cost of a wire rope hoist.
