ShuangqiaoElectric lifting platform 2 metersWhat is it for?

Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.

Construction electric elevators outside the lightning protection range

Shuangqiao.Check whether the sealing of components such as the oil cylinder, oil pipe, and motor of the aluminum alloy electric elevator is good and whether there is any air leakage.

When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts should comply with the provisions of Table 4 of GB 23821-2009.

.After the electric elevator passes the inspection, the user unit shall organize the leasing unit, installation unit, and supervision unit to conduct acceptance. For the implementation of construction general contracting, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.

Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications as specified in the above table.

To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.

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.

Setting requirements: Buffers should be installed below the suspension cage and counterweight running channel.

The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.

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

Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.

The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.

Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form, and concrete strength report.

Lets see.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,ShuangqiaoElevator scissor electric, 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,ShuangqiaoZoomlion Electric Elevator, sticky, or has foreign objects such as gravel, 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,Shuangqiao2 ton electric elevator, clean it with compressed air, and then return it to the oil tank and connect the pipeline.

Stop the suspension cage.

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, and then return it to the oil tank and connect the pipeline.

Shuangqiao.Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results, and report any problems found to the user unit.

Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.

When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
