How to use the jib crane safely
Jib cranes are also called cantilever cranes and jib cranes. Its structure is unique and its handling is different from other lifting equipment. So how to use jib cranes safely, the following content will answer this problem for you:
First, turn on the power switch, the switch of the overweight prevention device and the alarm device, adjust the position or gear of the indicator switch of the relevant instrument, and see the reading of the hydraulic oil pressure gauge. After all adjustments and checks are complete, you can operate:
Second, the rotation operation. (1) Honk the horn before the turning operation; (2) After releasing the turning brake, the turning operation can be carried out; (3) The turning operation lever must be operated smoothly, so that it is gentle and stable when starting and stopping. During the turning movement, If you want to turn in the opposite direction, you should stop first, and then turn in the opposite direction;
Third, the boom luffing operation. (1) The boom descends steadily; (2) Achieve smooth operation, observe the load swing and operation trend;
Fourth, the boom telescopic operation. (1) It is forbidden to extend and retract the boom under the condition of heavy lifting. In special cases, when the boom is extended with a hanging object, it must be rated; (2) When the boom is telescopic, pay attention to the lifting height of the hook to prevent The end of the boom collides with the hook pulley block;
Fifth, lifting and lowering operations. (1) The operation of the free-falling pedal should be stable, and the operation should not be too strong, and should not cause excessive vibration and shock, so as to avoid the deformation of the boom or the overturn of the crane; (2) When ensuring that the pressure of the accumulator is within the specified value, Operate the operating lever steadily, and it is strictly forbidden to lift heavy objects suddenly, so as not to damage the oil motor or boom, etc.; (3) The empty hook can fall freely and is used to drop heavy objects. The weight must be less than 30% of the rated lifting capacity.
The hoisting jib crane is a new-generation light-duty hoisting equipment manufactured to adapt to modern production. It can be widely used in factories, mines, workshops, production lines, assembly lines, and machine tools up and down warehouses, docks and other occasions for heavy lifting. The reliability of this small crane is so high that it is widely used. Therefore, it is necessary to study and understand carefully when lifting jib cranes in order to have safety hazards.
