Top 10 Crane Terms to Know
Leave a CommentChoosing the right crane for your business can be challenging. If you are exploring different material handling systems for your company, here are the top 10 terms you will need to know to help narrow down the search:
1. C.M.A.A. – Crane Manufacturers Association of America, Inc. (formerly known as EOCI – Electric Overhead Crane Institute).
2. Critical Load – A load that, if released or moved without the proper control, could compromise the safety of the entire system. A crane lifting a critical load requires a single failure proof feature (defined below as term #8) so that any possible failure will remain isolated and not halt the rest of the load.
3. 
Explosion Proof Crane – Specially designed cranes with electrical components that keep any potential explosions contained within the components, therefore preventing any accidental ignition of hazardous materials in the surrounding air.
4. Flux Vector Drive – A closed loop system that uses an adjustable, incremental encoder to monitor the speed and direction of a crane’s motor shaft. This control provides systems lacking a mechanical load brake with more reliability and a greater range of speed.
5. Lift – The highest safe point at which the crane’s hook, magnet, and buck can move.
6. Load Block – The assembly of all crane accessories including the hook, swivel, bearing, sheaves, pins, and frame, suspended by the hoisting ropes.
7. Overhead Crane – A type of crane that works from an overhead fixed runway structure. It includes a moveable bridge carrying either a moveable or stationary hoisting mechanism.
8. Single Failure Proof – Mentioned earlier as a consideration for critical load (#2), single failure proof safety features ensure that the failure of one component will not compromise the rest of the load. The crane will maintain control of a critical load, even if one component fails.
9. Top Running Crane – A model of overhead traveling crane that runs along rails with truck ends attached to runway support beams.
10. Wheelbase – The length from the center of each wheel, measured parallel to the support rail.
