A crane cycle consists of a pick-up device that lifts the article from the pick-up point, then moves horizontally to a designated location to lower the article, followed by a reverse motion that returns the pick-up device to its original position for the next cycle. Usually the lifting machine by the lifting mechanism (so that the up and down movement of the goods), running mechanism (so that the lifting machine to move), amplitude mechanism and slewing mechanism (so that the goods for the horizontal movement), plus the metal mechanism, power unit, manipulation and control and the necessary auxiliary devices combined into. In a certain range of vertical lifting and horizontal handling of heavy objects within a certain range of multi-action lifting machinery, also known as crane. It is mainly used for lifting and transporting finished goods, equipped with appropriate spreader can also be lifting and transporting bulk materials and liquid materials. Crane's work is characterised by intermittent movement, that is, in a working cycle of picking up, transport, unloading and other actions of the corresponding institutions are working alternately. The institutions are often in the starting, braking and positive and negative direction of the working state.

A complete list of common crane accessories products
Wire Rope
Check the wire rope specifications, models and slip drum match is in line with the design requirements. Wire rope fixed end clamps, rope cards, such as the block of wire rope fixed installation to meet the requirements. Wire rope wear, broken wire, kinking, flattening, bending, broken strands, corrosion, etc. whether to exceed the standard.
Crane hook
Check whether the crane hook and anti-dislodgement equipment to meet the requirements, hook cracks, peeling cracks and other defects; hook section wear, openness increase, torsional deformation, whether it exceeds the standard; hook neck and surface fatigue deformation and cracks and related pins, sets of wear.
Coupling
Coupling parts have no defects, loose connection, running impact phenomenon. Coupling, pin, pin hole, cushioning rubber ring wear exceeds the standard. Is the coupling concentric with the two parts being connected.
Drum
The drum body, drum edge has no fatigue cracks, damage, etc.; the rope groove and the drum wall wear exceeds the standard; the height of the drum rim and the number of layers of wire rope winding can be matched; the rope guide, the rope discharge device work in accordance with the requirements;
Braking device
Brake settings, brake type is in line with the design requirements, brake lever, spring fatigue deformation, cracks and other defects; pin, mandrel, brake wheel, brake friction pads whether the wear exceeds the standard, hydraulic brake oil leakage; brake clearance adjustment, braking capacity can meet the requirements.
Wheel
Wheel tread, axle fatigue crack phenomenon, wheel tread axle wear is excessive. Whether there is a gnawing phenomenon in the operation.
Reducer
When the reducer is running, is there any violent metal friction sound, vibration, shell radiation and other abnormal sounds; is the seal of the shaft end intact, whether the fixed bolt is loose and defective; reducer lubricant selection, oil level, vertical reducer lubricant pump operation, open gear drive lubrication and so on whether it is in line with the requirements.
