Electric hoist bridge crane This is a common type of crane on the market, with high and frequent usage, leading to weaker durability of the bridge crane attachments. Therefore, this document briefly explains how to inspect and maintain the electric hoist of a bridge crane after damage.
1. Carefully check the main control circuit of the electric hoist bridge crane and cut off the power supply to the hoist motor; prevent sudden burnout of the main circuit and control circuit, three-phase motor with power supply, or cause great harm to the incoming line operation of the hoist motor.
2. Next, pause and gently push the switch, carefully check and analyze the control electrical appliances and wiring. Repair and replace electrical appliances or wiring until there are no faults in the main circuit and control circuit; start.
3. When the motor terminal voltage of the electric hoist bridge crane is found to be lower than the rated voltage by 10%, the cargo cannot be started and cannot operate normally. At this time, it is necessary to use a life termination table for pressure measurement.
The damage caused by the suspension bridge is caused by human operation and does not belong to the quality problem of the electric hoist. The number of parts that need to be replaced is currently unknown. Due to the large number of parts to be replaced, the equipment and parts are not complete in on-site maintenance. The business trip expenses of maintenance personnel are also relatively high. Considering the comprehensive factors, the manufacturer recommends Electric hoist bridge crane Returning to the factory for repair. The user shall bear the round-trip freight, spare parts fee, repair fee, packaging fee, etc. This is a fast, cheap, and convenient way.
Lifting equipment is a type of engineering machinery that lifts, lowers, and moves heavy objects to a designated location. There are many forms, including electric hoist series, crawler cranes, tire cranes, truck cranes, cable cranes, steel pipe masts, bridge cranes, tower cranes, etc. Its basic technical parameters mainly include: lifting weight, lifting height, span, amplitude, working speed, productivity, working level, etc. Electric hoist bridge crane It has the characteristics of large working area and wide application occasions, greatly reducing the labor intensity of operators. It is a commonly used important labor tool in factories, mines, docks, warehouses, yards, dams, power generation projects, etc.
