Self-propelled Scissor Lift Daily Use Experience Sharing
The mobile scissor lift platform is a product that serves mobile high-altitude operations such as high-altitude operations, equipment installation, and maintenance in various industries. Because of its working environment, it must be maintained regularly. This is a necessary way to ensure its functions:
1. Check the oil quality and oil level of the hydraulic oil. The lifting platform rises all the way up. In this position, the hydraulic floor should be 40-50mm higher than the bottom of the box. If the hydraulic oil is found to be dark, sticky, or has foreign matter such as gravel, it should be replaced in time (32# hydraulic oil). Year-end maintenance of lifting platform Checks all hydraulic pipes and joints. The hydraulic oil should be replaced once after 1000 hours of use or should be replaced immediately if the oil is found to have deteriorated midway. Check the filters of the suction and return lines in the tank (annual).
2. Check the engine and battery. The maintenance of power components must also be carried out at the same interval and method as the car.
3. Check oil pipes, pipes, and filters. The pipes must not be damaged, the joints must not be loose, and all joints must be tightened. Remove and disassemble the lifting platform down valve, blow out the plunger with compressed air, then install it and reinstall it. Drain the hydraulic oil and discard it, tighten the joint to take out the oil filter, clean it with compressed air, put it back into the oil tank, and connect the pipeline. (Replace with new oil, do not continue to use old oil. Otherwise, the moving parts in the hydraulic lift system will accelerate wear.)
4. Check whether the rollers of the aerial work platform, the intermediate shaft and the shaft lift bearing, the pin shaft and bearing of the oil cylinder, the hinge shaft of the boom and the bearing are worn or not. All parts are filled with some lubricating oil to prolong the service life of lifting platform components.
5. Mobile scissor lift platform slewing bearing and other hardware. The slewing bearing should be tightened regularly with a torque wrench according to the specified number, and check whether the appearance of the equipment is damaged.
(1) Check the rotating system and lubricate the worm system (adjust the worm if necessary).
(2) Check the fixing bolts, pins, and connecting screws.
(3) Check that all labels, signs, trademarks, etc. are in place and visible.
(4) Check whether all signal lights are normal.
(5) Check the carbon brushes of the DC motor.
(6) Check whether the paint surface is peeled off.
(7) Check whether there are cracks at each weld.
In the process of daily use of the lift, we may encounter many emergencies. The most important thing is how to operate correctly when the Self-propelled scissor lift system suddenly fails. Shandong Cathay Machinery Co., Ltd explains this situation in detail here：
1. Do not move in a panic to prevent the table from shaking. Slowly adjust the pressure relief valve to let the table drop slowly until it reaches the ground.
2. Check whether the line of the mobile lift is damaged and whether the lifting switch is operating normally. A fault in the line will cause the button to fail. If the equipment is in normal operation, it is generally a line fault.
3. Check whether there is any object pressing the solenoid valve. If the solenoid valve is used for too long, the performance will be damaged, and the device button will also fail.
4. Check whether the electric control switch is normal, because the frequency of use of the electric control switch is high and it is easy to be damaged, so it is necessary to do a good job of maintenance.
5. Verify whether the power supply of the hydraulic lift is connected, and check whether the power indicator light of the lift system is normal.
When the mobile lifting platform system fails, you must be calm, because our equipment is equipped with safety protection devices, you must deal with it calmly, and at the same time, you must do a good job in the daily maintenance of the elevator to prevent problems before they happen.
