KaiserslauternMobile electric elevatorQualified testing standards

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, 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, tighten the joint, remove the oil filter, clean it with compressed air, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the landing speed does not change due to heavy objects. It is adjusted by the saving valve

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.

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.

Drain and discard the hydraulic oil, tighten the joint, remove the oil filter,KaiserslauternScissor fork electric elevator, clean it with compressed air, and then return it to the oil tank and connect the pipeline.

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, all components should be inspected,KaiserslauternMicro electric hydraulic elevator, and standard sections and other components with severe wear and deformation should be replaced.

Precautions during operation: Mechanical operations should be gentle and smooth, and mechanical operations should be avoided, otherwise impact loads will inevitably occur, causing frequent mechanical failures and greatly shortening the service life. Generated during homework

Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.

Installation material list.When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.

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.

When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.

Acceptance: Concrete strength grade C30 strength testing report.

Bidding.Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.

Construction electric elevators should be equipped with upper limit switches that are sensitive and reliable.

Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.

Kaiserslautern.When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements, and the top floor height can be installed at least 2.5 meters.

Mechanical devices controlled by cage movement should not be used to open or close the landing door.
