Excellent cleaning and maintenance is a way to ensure the smooth operation of elevator spare parts, and it is also a direct way to ensure that people take the elevator safely.
Please pay attention to the following maintenance after the operation of landing door lift is completed, the following is a list for us:
1. Assuming that the landing door lift is placed for a long time, check whether there are traces of wear on the rollers, central shaft and bearings, cylinder pins and bearings, bearings and boom hinge shafts; hydraulic oil concentration, oil quality and oil level; hydraulic oil level should be high 45-50 mm from the bottom of the box.
2. The mobile landing door lift must support the outriggers during operation, adjust the outrigger bolts to make it stably bear the force on the outriggers, and be sure to maintain a balance.
3. During the lifting movement and lifting state of the landing door lift, the lifting channels are not allowed to move at will, shaking on the lifting platform is prohibited, all parts should be wiped clean, and the work platform should be lowered to the position when not operating to prevent the surface of the piston rod from rusting.
Choose special personnel to operate and keep, and any non-electrical personnel or operators shall not disassemble and assemble electrical appliances at will.
4. Elevator spare parts must be checked before use. Firstly, check whether the control buttons are really useful, the safety fastening function of the bolts at each junction, the stability of the guardrail, and whether the power cord and socket are all in good appearance and the quality is good.
