Safety operating procedures for Isuzu truck-mounted cranes
December 19, 2023
The main function of Isuzu truck-mounted crane is to lift and transport cargo. It can be quickly erected on site and enables efficient lifting operations. Truck-mounted cranes can provide a large amount of lifting capacity and working range to meet various lifting needs. In addition, the truck-mounted crane is also flexible and mobile, and can quickly arrive at the site and carry out operations without the need for additional crane equipment.
Isuzu truck-mounted cranes are mainly used in construction, road maintenance, ports, factory workshops and other places. It can be used for hoisting and installing construction materials, equipment, construction machinery and other heavy objects, and can also be used for repairing and cleaning roads, dock equipment and other work.
The following introduces the operating steps of the Isuzu truck-mounted crane:
1. Observe the operating environment of the truck-mounted crane, select a suitable angle for lifting operations, ensure that there is enough space for the left and right outriggers to be fully opened, and at the same time, park the truck at a suitable distance from the cargo according to the weight of the cargo;
2. Start the car, hang up the power take-off, and keep the power take-off in working condition. The specific operation is to step on the clutch, put the transmission handle in neutral, start the car, and observe the air pressure value. When it reaches 0.5-.06Mpa, the power take-off will be taken off. Pull out the manual air valve of the power tool and slowly release the clutch. At this time, the clutch is in working condition;
3. Only after completing the pre-operation inspection of the XCMG truck-mounted crane can the crane be used to operate the outriggers and boom;
4. Move the selector valve to the outrigger position on the sign, operate the outrigger, open the movable outrigger locking device, and extend the left and right horizontal outriggers and the left and right vertical outrigger cylinders according to the corresponding marks on the operating lever to ensure that the outriggers are Fully extended to support crane;
5. After the outrigger cylinder supports the crane, move the selector valve to the crane position on the sign, and use the crane to perform hoisting operations.
Things to note before work:
1. Before using the crane, you need to ensure that the outrigger cylinders are fully opened and the outriggers are locked. The outrigger cylinders are on the ground and the car cannot be suspended in the air. All wheels of the car must be on the ground;
2. Before turning on the power take-off, check whether the control handle is in the neutral position. If the handle is not in the neutral position, return it to the neutral position;
3. Check whether the stop valve on the hydraulic oil tank is open. If not, be sure to open it and check the amount of oil in the tank. The oil level must not be higher or lower than the maximum or minimum mark;
4. Ensure that the car has enough fuel to avoid power interruption during work. At the same time, check whether the battery pack is normal to ensure that it can start at any time in the event of power interruption;
5. Before using the crane, check whether the safety device of the crane is working properly;
6. Check the entire power pipeline to see if there is any oil leakage or pressure loss.
Precautions during operation:
1. Operating and lifting heavy objects should be on the same side to ensure proper viewing angle and safe operation;
2. Expand and use the crane correctly according to the signs corresponding to the operating lever.
3. When the hook is lowered, at least 3 turns of wire rope should be retained on the drum;
4. When the wear of the outer steel wire of the steel wire rope reaches 10% of its diameter, the steel wire rope should be scrapped;
5. Before lifting the goods, the weight of the goods must be estimated. This value must be compared with the rated load on the lifting moment, and the line from the point of descent of the goods must be calculated.
Things to note after operating the truck mounted crane:
1. Be sure to ensure that the movable outriggers are fully retracted, and check whether the locking assembly is locked;
2. After the work is completed, disconnect the hydraulic pump from the power take-off device. After the operation is completed, check whether each control handle is automatically reset. If the handle is not in the neutral position, return it to the neutral position.
3. Move the selector valve to the leg position on the sign;
4. Place the locking assembly lever in the open state and open the movable outrigger locking device;
5. Retract the left and right vertical outriggers and horizontal outriggers according to the operating instructions;
6. After each movable outrigger has shrunk a few centimeters, return it to the locked state, then retract the movable outrigger into position, and the locking assembly rod will automatically embed and lock;
7. Close the power take-off;
8. Turn off the power.
