lift truck and tow boom lift as a common tool for aerial work, with high efficiency, excellent safety performance, simple operation and other characteristics, sometimes encountered failures in the operation process. In order not to delay the use of everyone, we should master some common maintenance knowledge. Let me talk to you shortly about common failures.
1. The lifting platform vehicle cannot rise to the set height. In this case, check whether the hydraulic oil in the tank meets the standard capacity and whether the tank leaks oil. If the hydraulic oil is not sufficient, please add the specified hydraulic oil.
2. The static electricity of the lifting platform car does not rise or fall, because there is no grounding wire when wiring, resulting in the static electricity of the lifting platform car leading to the failure of the electric box, which can be grounded with iron products.
3, lift platform car can only rise, can not fall: check whether the solenoid valve indicator light is bright, press the drop button on the electric box, if the solenoid valve is not bright, check whether the solenoid valve two lines open or loose.
4, lifting and shaking platform, check whether there are tiny particles, garbage, lubricating oil in the chute, please add in time, otherwise long-term wear will lead to the lifting platform car stuck to damage.
If the elevator flat wagon or collision, surface peeling paint should be timely to fill paint to replace the damaged parts, some should satisfy the lubricating oil should be regularly check, repair or replace the mechanical parts, bolts, especially usually loose support pin, such as reverse connection bolt support, lift arm should check whether the loose, if loose, should tighten or replace immediately, give up the hydraulic oil, Tighten the joint, remove the oil filter, wash it, wash it with compressed air, then return it to the tank and connect the pipe.
