The 20 precautions for the use of bridge erecting machines are for the safety of the construction personnel. The accidents of this equipment are basically human lives. As long as you cherish your life, please read the following precautions carefully. The 20 precautions for the use of bridge erecting machines are for the safety of the construction personnel. The accidents of this equipment are basically human lives. As long as you cherish your life, please read the following precautions carefully. 1. Each construction hoist
must be hung with a sign of the rated lifting capacity in an obvious place. 2. During work, no one is allowed on the bridge or transporting people with hooks. 3. It is not allowed to drive the bridge machine without operating license and drinking. 4. The operation must be concentrated, no talking, smoking or doing irrelevant things. 5. The vehicle must be clean and clean; no equipment, tools, flammable materials, explosive materials and dangerous materials are allowed to be placed indiscriminately. 6. Overloading of construction hoist is not allowed. 7. Lifting is not allowed in the following situations: loose binding; overloaded machinery; unclear signal; oblique pulling; objects buried or frozen in the ground; people on the objects to be hoisted; flammables, explosives, and Dangerous goods; liquids that are overfilled; the steel wire rope does not meet the requirements for safe use; the lifting mechanism is malfunctioning. 8. When the construction hoist runs on the line without obstacles, the hook or spreader and the bottom surface of the hanging object must be more than 2m from the ground. If you cross the obstacle, it must exceed the obstacle by 0.5m. 9. For lifting objects less than 50% of the rated lifting weight, two mechanisms are allowed to operate at the same time; for lifting objects greater than 50% of the rated lifting weight, only one mechanism can operate. 10. For bridge erecting machines with main and auxiliary hooks, do not raise or lower the main and auxiliary hooks at the same time (special exceptions). 11. Welding or hammering on the hoisted object and working under the object are not allowed (it is possible when there is support). 12. The inspection or maintenance work must be done after a power failure and a power failure sign is hung on the switch. If it is necessary to work on electricity, it must be protected by safety measures and has a dedicated person to take care of it. 13. Don't throw things down from the car casually. 14. Limit switches and interlock protection devices should be checked frequently. 15. It is not allowed to touch the limit switch as a method of stopping. 16. When there is a problem with the lifting brake, it is not allowed to lift heavy objects. 17. The suspended objects are not allowed to run over people or equipment. 18. When welding a certain part of the bridge erecting machine, it is necessary to set up a ground wire, and it is not allowed to use the fuselage as a ground wire. 19. When the hook is at the lower limit position, there must be more than two safety rope loops on the reel. 20. The bridge erecting machines are not allowed to collide with each other, and it is not allowed to use one bridge erecting machine to push another bridge erecting machine to work. The precautions for the use of bridge erecting machines are naturally more than that. As long as you go to the construction site, you will know more rules and regulations. There are indeed too many relevant specifications for this thing, and an article can't finish it. If you need lifting equipment, you can find our company to cooperate.
However, with the increased prevalence of suspended working platform
, it has become far more affordable.
