1. Pre-operation inspection and maintenance Before the on-board crane truck operation, the on-board crane truck shall be inspected and prepared for maintenance in accordance with the requirements of the maintenance manual. The engine shall then be started and inspected under neutral conditions. Various instruments to check whether there is space overhead power lines or obstacles within the scope of work. After confirmation, you can prepare for operation.
2. The no-load operation separately starts the various mechanisms of the truck-mounted crane truck for no-load operation, controls each control system (or control device), checks whether the operation and operation of the mechanism is normal, and whether the brake of the lifting mechanism is safe and reliable, and adjusts if necessary. . For hydraulic truck cranes, the oil pump and the power output shaft are also connected to the station and the hydraulic oil is preheated at an idle speed so that the oil temperature meets the specified requirements and the liquid helium in the hydraulic system is ensured to be smooth.
3. Boom Telescoping For the telescopic boom structure, the boom stretches through the post ten. In the synchronous telescoping mechanism, it is checked whether the protruding length of each boom is equal, so as to ensure that the stress can be evenly distributed on each section of the boom. Boom telescopic movement should be slow, load conditions, generally should be prohibited telescopic boom. The boom angle of the crane boom must not exceed the specification value.
4. Inspection and Adjustment After Lifting The lifting loader lifts the rated cutting load. It shall stop lifting at a height of 200 to 300 mm from the ground, check the physical position of the goods, sling binding, partial load, and the performance of the brake. Stability, boom deformation, and leg pressure are all normal and reliable. After confirmation, you can continue to raise. If it is found that the center of gravity of the cargo shifts, the slings and lashings are suspicious, the brakes are slipping, the supporting legs are softly subsiding, and the whole machine is abnormally tilted, and the load should be adjusted immediately afterwards to prevent accidental illusions.
5 Legs Operation Sequence The lifting truck is not allowed to operate without legs. When the outriggers are extended, the operation can be performed by stretching the rear legs first and then extending them forward. When retracting the legs, first shrink the front legs and then retract the legs.
6. Gravity drop and operation of the air hook and hoisting below 30% of the rated weight, gravity can be used to drop. But must pay attention to the slow operation, so that the weight falls from its own weight.
