Application area
Application areas: lifting, towing, handling of heavy loads, welding of oil tanks, such as installation and movement of various large and medium-sized lumbers, steel structures and mechanical equipment, applied to infrastructure works such as construction companies, civil construction works and construction of bridges at plant mines, electricity, ship, car construction, construction, roads, bridges, metallurgy, mines, slope tunnels and wells management protection。
Use maintenance
1. Newly installed or detachable electron berylliums shall first be operated on empty vehicles several times. However, until it is installed, it is forbidden to turn through electric tests。
2. Prior to normal use, a static load test of 125 per cent at rated loads, rising from the ground by about 100 mm for 10 minutes, shall be conducted to check the normality。
3. The load test is a rated load mass, which is tested for repeated lift/down and movement to the left, after which the mechanical thrust component, electrical components and connections are checked for reliability。
In use, it is prohibited to use in an impermissible environment, in excess of the rated load and in the number of times the rated gates per hour (120)。
5. When debugging and maintenance is installed, the flexibility and reliability of the limit mechanism must be strictly checked and, when the hook rises to the upper limit, the length of the shell from the hook to the cylinder must be greater than 50 mm (10t, 16t, 20t must be greater than 120 mm). When the hook drops down to the bottom limit, a wire-line safety circle should be guaranteed on the cylinder, with an effective safety circle of more than two laps。
It is not permitted to press two electric buttons that allow electric thallium to move in the opposite direction。
7. Once completed, the main gate of the power must be removed and the power must be cut。
8. The electron beam should be operated by a single person, who should be fully equipped with safety protocols and strictly prohibited from slashing。
9. In their use, electric thorium must be regularly inspected by specialized personnel, failure detected, timely measures taken and carefully documented。
10. When adjusting the volume of the brake drop, the amount of the brake drop s≤v/100 (v is the distance from which the load is stable to rise within one minute) shall be guaranteed under the rated load。
11. End-of-life standards for wire ropes: the tests for steel wire ropes and end-of-life standards are implemented in accordance with the cb/t5972-1986 practical instructions for the use of steel-line tests and end-of-life in gravity mechanics。
12. The use of electron beryllium must be maintained in sufficient quantities as well as clean and should not contain impurities and dirt。
13. The oil on the wire line shall be made from a hard brush or small piece of wood, and direct hand-to-work oil shall be prohibited。
14. When the electron beryllium is not working, it is not allowed to hang heavy matter in the air to prevent the parts from being constantly deformed。
In the course of use, if malfunctions are detected, the main power source shall be cut immediately。
16. Particular attention should be paid to vulnerable items in their use。
17. 10 ~ 20 tonnes of thorium may be automatically out of power after a long period of continuous operation, which is an overheating protection function of the electric power, which can be reduced at a time when it can continue to work after cooling down。
