Lifting equipment parts supplier introduces you: a working cycle of the crane includes: the picking device lifts the item from the picking place, and then moves horizontally to the designated place to lower the item, and then performs the reverse movement to make the picking The device returns to its original position for the next cycle. Generally, lifting machinery is composed of a lifting mechanism (moving the object up and down), a running mechanism (moving the lifting mechanism), a luffing mechanism and a turning mechanism (moving the object horizontally), plus a metal mechanism, a power unit, and control. And necessary auxiliary devices. A multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a crane. It is mainly used to lift a single item, and it can also lift bulk materials and liquid materials when equipped with appropriate spreaders. The working characteristics of cranes are intermittent movements, that is, the corresponding mechanisms of actions such as taking, moving, and unloading in a working cycle alternate. Each mechanism is often in the working state of starting, braking and running in the forward and reverse directions.

8 common crane accessories
1. Wire rope.
Check that the wire rope specifications, models, and drums match the design requirements. Whether the fixed installation of wire rope fixed end clamps, rope clips, deeds, etc. meets the requirements. Whether the wire rope is worn, broken, kinked, squashed, bent, broken, or corroded.
Check whether the crane hook and anti-dropping equipment meet the requirements, whether the hook has cracks, peeling cracks and other defects; the hook cross-section wear, the increase in opening degree, torsional deformation, whether it exceeds the standard; fatigue deformation of the hook neck and surface and cracks and related Pin and sleeve wear.
Coupling parts with or without defects, loose connections, and operating shock. Are the couplings, pins, shaft pin holes, and buffer rubber rings worn out? Whether the coupling is concentric with the two parts being connected.
Are there any fatigue cracks or damages on the drum body and the drum edge? Whether the rope groove and the drum wall wear exceeds the standard; whether the height of the drum rim and the number of winding layers of the wire rope can be matched; whether the working conditions of the rope guide and the wire rope are consistent Claim.
5. Braking device.
The setting of the brake, whether the type of the brake meets the design requirements, whether there are defects such as fatigue deformation and cracks in the levers and springs of the brake; whether the pins, mandrels, brake wheels, and brake friction discs have exceeded wear and tear, and whether hydraulic brakes have leaked oil ; Whether the brake clearance adjustment and braking ability can meet the requirements.
Whether the pulley is equipped with an anti-off rope groove device; whether there are cracks, broken edges, and excessive wear on the rope groove and rim of the pulley;
Whether there are fatigue cracks on the wheel tread and axle, and whether the wheel tread has worn axles. Whether or not the track phenomenon occurs during operation.
Are there any abnormal sounds such as severe metal friction noise, vibration, and shell radiation during the operation of the reducer? Whether the shaft end is intact and whether the fixing bolts are loose and defective; etc .; Lubricant selection, oil level, and vertical reducer lubrication Whether the oil pump operation and open gear transmission lubrication meet the requirements.
Lifting equipment classification
Lifting equipment can be divided into light and small lifting equipment, lifts, cranes and overhead monorail systems according to different structures. Light and small lifting equipment mainly includes lifting tackles, spreaders, jacks, manual hoists, electric hoists and ordinary winches. Most of them are small in size, light in weight and easy to use. Except for electric hoists and winches, most of them are driven by manpower, suitable for occasions where the work is not heavy. They can be used alone or as a lifting mechanism for cranes. Some light and small lifting equipment have a large lifting capacity, for example, the lifting capacity of hydraulic jacks has reached 750 tons. The lift is mainly used for vertical or near vertical lifting movements, and has a fixed lifting route, including elevators, lifting platforms, mine elevators and hopper elevators. A crane is a multi-action lifting device that vertically lifts and carries heavy loads horizontally within a certain range.
