What should I pay attention to when operating a single beam crane?

The single-beam cranes used by enterprises are generally more than 3 tons, which are special equipment. When operating, you must pay attention to work safety. The editor will introduce you to what you need to pay attention to when operating a single-beam crane.

First, the first thing to note is that when using a single-beam crane to lift heavy objects, the hook wire rope should be kept non-vertical and the suspended objects should be dragged diagonally. The center of gravity should be found and bound. . When lifting or lowering the weight of the crane, the speed should be uniform and stable to avoid sudden changes in the air, which may cause the load to swing, which is dangerous.

Second, there are no people staying within the crane's operating range, and people should try to avoid passing them. When the two cranes hoist objects, the weight should not exceed 75% of the total weight of the two cranes. The two cranes travel and immerse to the same action. According to the relevant regulations on the specific requirements of crane wire ropes.

Third, when the wind power of the outdoor crane exceeds level 6, it should stop working immediately. Cut off the power and pull the wind rope. Usually the same thing should be done after get off work. It is strictly forbidden to pile up miscellaneous objects on the crane platform. In order to prevent the operation from falling and hurting people, the frequently used tools should be placed in the special toolbox in the operation room.

Fourth, when the crane is running, the operator's hand should not leave the crane remote control. If a sudden failure occurs during the operation, measures should be taken to land safely, and then the power supply should be cut off and repaired. It is strictly forbidden to operate, and immediately find professional maintenance staff to come and repair it.

Matters needing attention before single beam crane work

a. Before a single-beam crane with a cab, and the driver take over, the hook, wire rope, safety device and other components should be inspected according to the requirements of the check card, and abnormal conditions should be eliminated if they are found.

b. For ground-operated single-beam cranes, each shift should have a special person responsible for inspection according to the requirements of the check card, and abnormal conditions should be eliminated if they are found.

c. The operator must confirm that there is no one on the platform or track before turning on the main power supply. When the power circuit breaker is locked or there is a notice board, the main power supply can be turned on only after the original person concerned removes it.

Matters needing attention in the work of single beam crane

a. When lifting a heavy object for the first time in each shift (or when the load reaches the maximum weight), the weight should be lowered after the height of 0.5 meters from the ground, and the brake performance should be checked. After the reliability is confirmed, the normal operation can be carried out.

b. Strictly implement the " Ten No Hanging " system:

① The command signal is unknown or the command is not suspended;

②Do not hoist when the lifting capacity exceeds the rated capacity;

③Unreasonable use of slings or inadequate hanging of objects;

④There are people or other floating objects on the hanging objects.

⑤If the brake or other braking safety device fails, do not hang;

⑥ Do not hang heavy objects when they are directly processed by crane;

⑦Hanging slantingly without hanging;

⑧ Do not hang explosive objects;

⑨ Objects buried in the ground shall not be pulled out;

⑩ Objects with edges and corners are not hung if they are not properly cushioned;

c. If an abnormality is found, immediately stop the machine, cut off the power supply, check the cause and eliminate it in time.

Matters needing attention after single girder crane work

a. Raise the hook to a certain height, park the cart at the designated position, and place the controller handle at the "zero" position; pull down the knife switch and cut off the power supply.

b. Perform daily maintenance.

c. Do a good job of handover.

When using a single-beam crane, you must abide by the operating regulations, and pay attention to the safety of the equipment and the personal safety of the staff.
