Lifting machinery and their functions and structural features
 
Lifting machinery and their functions and structural features can be divided into small light lifting equipment, cranes and lifts. Crane is the most important performance parameters from the weight and working level, in addition to the span, track ...... etc.
Typical general overhead cranes are:
(1) Hanging overhead cranes: a basic type spreader is the hook, and versatile.
(2) Bridge Crane: heavy with grab for bulk material handling lifting work.
(3) Electromagnetic bridge crane: extract is electromagnetic sucker for lifting the metal material having permeability.
Mobile crane is a constantly changing workplace, to run along the road in the trackless load or no-load conditions, and rely on to maintain a stable weight jib crane. Typical mobile cranes are:
(1) Crane: The crane tipping section on general or special vehicle chassis, running speed, suitable for long distance conversion job site quickly. Good mobility but cannot travel with the load, through poor performance for highway accessibility, mobility, workplace dispersed.
(2) Tire crane: the use of special chassis, its rigid axle suspension, can hoist with strong off-road capability, more focused job site suitable for the occasion.
(3) All Terrain Crane: either high speed, there are strong through the rough road capability, you can hoist travel. Suitable for mobility, poor traffic conditions on site.
(4) Crawler crane: Tracked and ground contact, lifting heavy objects can travel, suitable for loose, muddy ground operations.
