The wire rope is the main force-bearing part of the crane machine. If the wire rope breaks during the operation, serious consequences may result, resulting in equipment damage and casualties. In order to ensure the safe use of the wire rope, it is necessary to regularly check and record the wire rope of the crane machine.When inspecting the crane machine wire rope, in addition to manual visual inspection, the caliper can be used for diameter measurement, or electromagnetic non-destructive testing can be used to check the internal condition of the wire rope.When inspecting, first check the diam ...
The electric hoist hook is made by forging and heat treatment. The forging process is a method in the metal hot working process, is the process of metal structure refinement and metal fiber arranging, and the heat treatment is to eliminate internal stress and further improve the mechanical properties of the metal, which can make the internal structure of the metal more compact.And, welding is the process of partial melting, fusion and solidification of metal.During repair welding, the electric hoist hook near the weld repaired joint is heated and cooled by different degrees due to heat conduct ...
The crane machine operation is a collective operation coordinated by the commander, the crane driver and the rigger. The safety quality of the personnel is the key to safe operation. Lifting operations require crane machine operators not only to have basic cultural and physical conditions, but also to understand relevant regulations and standards, to learn the theory and knowledge of lifting safety technology, and to master practical and safe rescue skills.Crane drivers must undergo special assessment and obtain a certificate to operate independently. Commanders and riggers should also undergo ...
1. The hook should be lifted more than two meters from the ground, the cart is parked at the designated position, the controller handle should be placed in the “zero” position; the knife gate is pulled down, the power is cut off, and safety is ensured.2. Carry out daily maintenance: a. The key of the power switch box is managed by the designated personnel. The electric hoist must be regularly maintained, inspected and lubricated by a special person to avoid accidents. b. Check the electrical equipment and control system and the hook for cracks or cold deformation afte ...
