Typically, a ute crane refers to a machine used for moving heavy stuff from one place to another. Unlike other transport mechanisms, cranes rely exclusively on lifting mechanism such as hoist ropes and sheaves to move loads vertically or sideways. The combination of the elements in the lifting mechanism gives cranes lots mechanical advantage needed in handling complicated loads. You can choose from a variety of lifting mechanisms depending on the ones that best suit your workstations. Of course, this requires you to consider things such as convenience, safety and fast cycle times when carrying the loads. Here is a look at some of the lifting solutions you can go for when choosing a crane:
Chain hoists are the first option you can consider for your crane's lifting mechanism. Due to the amount of weight involved, cranes do not use hand-held chain hoists. They use electric chain hoists with several equipment options to facilitate the movement of the load. Chain hosts have a compact headroom, which acts as the powerhouse of the whole system. A hook suspension is also added to the chain hoist, and its primary purpose is to provide a link between the whole chain hoist and the load in question. Lastly, a chain hoist is easily height adjustable to suit a variety of work stations. Actually, this is one of its top benefits.
Ideally, chain hoists should be used for moving loads weighing between one to five tonnes. Anything above that elevates the risk of snapping and resulting in serious accidents. The movement of the load should also be infrequent and the load itself should be less susceptible to damage.
Servo hoists are intelligent lifting mechanisms that allow the crane's operator to move and float a load vertically with good precision. Servo hoists are also fast compared to other lifting mechanisms such as chain hoists. Using computer programs not only guarantees speed but also ensures reliability in terms of the safety of the operators. Servo hoists can carry up to nine hundred kilograms.
To initiate and sustain natural lifting motions, cranes can also employ air balancers. They use compressed air to provide vertical forces that can move loads as heavy as five hundred kilograms. This eliminates the need for powered motors when moving loads in the workstations. The only problem is that they are limited in terms of their lifting capacity, and they may not be applicable for large projects.
