ZhejiangElectrThe counterweight guide rail should meet the specification requirements.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Zhejiang.Safety devices: Electric elevators for construction should be equipped with overload detection devices. When the load inside the cage exceeds 10% of the rated load capacity, the overload detection device will give a warning signal inside the cage,
Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
.Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width, and should not open towards the lifting passage.
The motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, improving the utilization rate of the wellbore area.
Later, when there is a major malfunction of the lifting platform, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents, personnel and property losses.
During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
It is strictly prohibited to use travel limit switches as switches to stop operation.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Range.Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky,ZhejiangElectric wire rope elevator, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.

Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.
Quality documents.For customers to use and operate the lifting platform for a long time, the editor briefly introduces how to maintain and repair the lifting platform: First of all, normal maintenance is mainly focused on prevention especially if any damage or malfunction is detected and corrected or repaired in a timely manner. Careful inspection and maintenance at this time can save costs and avoid larger problems, resulting in costly repairs.
Mobile electric elevators are divided into: four wheel mobile lifting platform, two wheel traction lifting platform, car modified lifting platform, manual lifting platform, manual lifting platform, it can cause the car to descend to the nearest floor position and open the door

Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, stable operation, low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table it can be stopped arbitrarily within the range of travel.
The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
