Preparation and operation of wire rope hoist is an important part of electric wire rope hoist lifting. In recent years, accidents involving electric wire rope hoists have occurred frequently due to poor preparation and operation. Wire rope hoist crane must be fully prepared.
First of all, there must be unified leadership and command for the project, and the weight of the lifting object, the number of electric hoists used, the number of personnel, and the work allocation of each position must be understood. Many things need to be considered in advance, and recorded in the book one by one.
Of course, one person cannot do many things at the same time. This requires teamwork. Personnel responsible for checking and confirming the actual situation of the construction site should report truthfully when discovered. They are also responsible for arranging the lifting operation of the entire electric hoist and controlling the pace of work. Each department must fulfill its responsibilities and do a good job.
Checking the electric hoist equipment is very important. Before each use, it must be carefully checked, including the loss of mechanical parts, whether replacement is needed, the sensitivity of certain electrical parts, whether it affects the normal memory of lifting operation, etc.
Then, according to the plan process formulated by the overall leadership group, relevant personnel and work content are deployed, and the progress is monitored during the project implementation to discover and make adjustments to problems in a timely manner. Ensure safe and rapid completion of the entire lifting operation of the electric hoist. This is the importance of preparation. Reducing the accident rate to a lower level and improving efficiency to a higher level is the common goal of everyone.
The operation steps of the lifting electric wire rope hoist must strictly follow the instruction manual. The specific steps are as follows:
Before starting the electric wire rope hoist, carefully check whether the equipment's mechanical, electrical, wire rope, hook, and limit switch are intact and reliable.
Do not overload when lifting the electric wire rope hoist. During the lifting process, do not put your hands between the rope and the object. When lifting, strictly prevent the suspended object from contacting the top.
When the electric wire rope hoist hoists an object, it must comply with the safety operating regulations of the forklift operator. Strap it firmly and set a buffering pad at the sharp corners of the item.
When the electric wire rope hoist is started by an electrical switch, good insulation is required. Press the button correctly and stand in the correct position during the operation.
When the single-track electric hoist goes around the corner of the track or approaches the end of the track, it must slow down.
Do not use the electric wire rope hoist frequently or repeatedly, otherwise it will cause the brake to heat up.
The electric wire rope hoist is not allowed to lift obliquely and horizontally drag.
It is forbidden to suspend the electric wire rope hoist for a long time to prevent parts from deforming.
If a serious malfunction is found when using the electric wire rope hoist, immediately cut off the main power supply.
After using the electric wire rope hoist, place it at a fixed point and lift it more than 2 meters.
Regularly check the electric wire rope hoist, promptly eliminate faults or potential hazards, and keep maintenance records.
