Lift rules of use
In elevators, hotels, terminals, and site operations, lifts are often used. In the daily use of lifts , special personnel should be responsible for normal maintenance and maintenance. The personnel who use can control the machinery to go up and down without walking down the lift table, and can control the equipment to travel to Other work sites on the countertop. The device itself has a walking and steering drive function, no manual traction, no external power supply. It is flexible and convenient to move and can make aerial work more convenient and efficient. It is an ideal high-altitude operation equipment for efficient and safe production of modern enterprises. While providing convenience for us, it also brings us many hidden dangers. Only standard operation and care of the machine can avoid the occurrence of safety accidents.
“The hidden dangers of building lifts are mainly before entering the construction site, during the installation and dismantling process, and during use.†Li Jianfang, chief engineer of the Changsha City Safety Supervision and Control Station, disclosed that the hidden dangers of construction elevators are mainly concentrated on: unlicensed posts; overloaded use; illegal installations. Demolition; The foundation does not meet the requirements; The attachment is not standardized; The crane structure is self-manufactured; The safety technology scheme is wrong; The goods lift is illegally carried. The problems with building elevators themselves are concentrated in the major structural rust, major structural cracks, loosening of connecting bolts, pin off, wire rope breakage, and damage to safety devices. When building a high-rise building, when the installation or the joint is not completed in time, the attachment device, the upper limit limit is not installed in time, and the bolt is not tightened, it is easy to cause the cage to climb and fall from a height.
Attention should be paid to the following points when lifting the elevator : 1. Before the normal work, it is necessary to check whether the battery has electricity, whether the circuit control system is good or bad, whether the main structure of the product is changed, and whether the rotation of the pin shaft is abnormal. 2. After use, it should be charged in time to ensure the battery's power. 3. If you do not use the lift regularly, check that the battery fluid meets the standard every 15 days. Check if the battery is charged. Charge it regularly. When checking electricity, check the battery water. If it is less than 20ml, you must add water. 4. Regularly lubricate the rotating pin of the product to ensure the normal lifting of the product. Check the hydraulic oil level and oil regularly to know how much oil and lifting power. 5, the hydraulic oil used should be kept clean, not mixed with water and other impurities, generally replaced every six months. The maximum working height of the lift can reach 12 meters and the carrying capacity can reach 450 kilograms. Lifts are mostly used for self-propelled scissor lifts. They are suitable for exhibitions, installation of heating, ventilating and air-conditioning systems, installation of fire-fighting pipelines, engineering of steel structures, and maintenance and repair operations at the factory floor.
Regulations on the use of lifts 1. Preparation before use 1.1 The visual inspection of the hydraulic lift truck should be performed before use. Operation must be performed when the operation is normal and safe and reliable. 1.2 Check whether there is oil leakage in the hydraulic lift truck tank. 1.3 Check the connection of each pipe, and if the fasteners and wire connectors are firm. 1.4 Check whether the platform guardrail connection is firm, the operating platform railing is completely reliable, and whether the operating platform bayonet is secure. 2, the operation step 2.1 walking operation When the legs should be taken back, rotate the adjustment screw, so that it can rise to normal walking height. 2.2 Lifting operation a. Turn the rotating leg to the diagonal position of the base, then turn the adjustment screw to level the whole machine with the aid of a level meter (Note: The level must be level). It is not advisable to remove all four wheels from the ground during leveling. b. When working against a wall, place the two legs on the wall parallel to the wall so that the platform is as close as possible to the wall for easy operation. c. Control system, close the leakage switch and turn on the power, the power indicator (red indicator light) is on, turn the switch to the lower control position. d. Press the green button on the top of the control box to rise. When the platform rises and rises to the height of the safety card, the card board is opened and lowered and lowered into the safety card slot. The fixed platform bayonet is locked and the lift truck is rising. When the button is released when the height is needed, the platform stops rising and keeps the pressure at the desired position. Press the red button to lower the platform, and release the button to stop the platform from falling. If you are controlling on the platform, you should set the switch to the upper control position and then operate the rising green button or the falling red button. 3. Working conditions 3.1 The altitude does not exceed 1000m. 3.2 The temperature is between minus 10°C and 40°C. 3.3 The wind power during work is not more than 4 levels. 3.4 The working ground should be solid and smooth, and the ground should not be sunk during the operation. 3.5 The allowable error of the operating supply voltage is ±10%. 4. Notices 4.1 The whole machine is forbidden to move after the platform is lifted. 4.2 Do not work when outriggers are not supported. 4.3 It is forbidden to carry live work on the platform. 4.4 When the platform is raised to the maximum height, the button should be released to stop. It is not suitable to operate at full load for a long time. 4.5 In case of sudden power failure after the platform rises, a small amount of loose oil drain valve may drop.
