Before using the fuel tank hydraulic jacking system, you should fully check whether the metal structural components and appearance are intact, whether the sound is normal when running at no load, whether the brake is reliable for heavy load testing, whether the safety limits and protection devices are intact, and the most indispensable Is the safety device reliable?
Here is the content list:
l What are the operational safety requirements for tank hydraulic jacking system?
l What is the safety device of the tank hydraulic jacking system?
l Specific operating rules for tank hydraulic jacking system.
1. Tank hydraulic jacking system drivers and signal personnel must be specially trained
2. Pay attention to whether the tower type learned by the tank hydraulic jacking system driver is consistent with the actual tower type
3. Implement a dedicated person and plane to manage tank hydraulic jacking system, captain responsibility system, and strict handover system
4. The newly installed tank hydraulic jacking system or the tank hydraulic jacking system after overhaul must be commissioned according to the instructions.
5. Keep a safe distance between tank hydraulic jacking system and overhead transmission lines
6. Applicable fire extinguishing equipment should be equipped in the driver's cabin of tank hydraulic jacking system
The installation of tank hydraulic jacking system shall not use aluminum conductor and screw steel as grounding body or underground grounding wire. The wires connected by bolts must have one end. There are three main ways to ground:
① The grounding body adopts regular grounding piles, or 33*4.5 long 1.5m steel pipe, or 70*70 long 1.5m angle steel.
② The grounding plate is made of steel plate or other ductile metal plate, with an area of 1 square meter and a depth of 1.5m from the ground.
③ Copper conductors with a cross-section of not less than 28 mm or steel conductors with a cross-section of not less than 50 mm are buried in the wire slot, and the buried length is determined by the grounding resistance.
In the above three methods, the cross-sectional area of the copper wire drawn from the grounding body should not be less than 25. If the soil is poorly conductive, sodium chloride (table salt) can be buried in the soil. Then fill it with water. For the tank hydraulic jacking system, each rail must be grounded, the two rails should be connected by a wire, and the two rails should also be electrically connected.
l About tank hydraulic jacking system safety device:
1. A safety device that prevents the sling on the hook from slipping off automatically.
2. Install a compression spring sheet at the opening of the hook head to close the opening. This spring sheet can only be pressed down and cannot be turned up after the sling is put in. It can prevent the sling of the tank hydraulic jacking system from falling off automatically.
3. Drum safety device: An effective measure to prevent accidents caused by improper winding of the steel wire rope beyond the drum.
4. A steel bar is welded outside the drum to restrict the wire rope to only move within the drum.
5. Fixed foundation: The digging trench is 600mm deep, concrete is poured on the lime soil, the surface is smooth, and there are waterproof and grounding protection measures.
Before use, check that the metal structural parts and appearance are in good condition, the sound is normal when running under no load, the brake is reliable in the heavy load test, the safety limit and protection devices are complete, and the action is sensitive and reliable before operation.
When operating each controller, it should be operated step by step, and it is strictly forbidden to operate over gear. When changing the direction of rotation, the operating handle should be reset to zero, and the motor should stop rotating before reversing the operation. Strive for stability, and it is strictly forbidden to start and stop.
During the operation of the tank hydraulic jacking system, if any abnormality of the machinery is found, it should be shut down immediately for inspection, and operation can only be carried out after the fault is eliminated.
It is strictly forbidden to work with a certificate, and it is strictly forbidden to work after drinking. It is strictly forbidden to use the travel switch to replace the parking operation. It is strictly forbidden to work in violation of regulations, leave the work post or give the machine to others to drive.
When loading heavy objects, you should leave the ground at a certain distance and check that the brake is reliable before proceeding.Insist on "ten" not hanging. After the operation is completed, the box should be powered off and the machine should be "crossed"!
