ShandongElectrThe use of standard section connecting bolts should comply with the user manual and specification requirements.
Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors, or other lower suspended structures, the bearing capacity of the foundation support structure should be checked. Click here to download the construction technical information for free. Basic drainage facilities should be installed.
Shandong.Setting requirements: Construction electric elevators should be equipped with a down travel (limit) switch. The down travel (limit) switch should be able to automatically stop the cage running at rated speed before reaching the lower limit switch.
The scaffolding of the parking platform should be laid tightly and firmly.
.Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width,ShandongHigh altitude electric elevator,ShandongElectric pillar elevator, and should not open towards the lifting passage.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.
Folding arm electric elevators are mostly driven by hydraulic means, and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high, can the folding arm electric elevator provide greater torque output thereby improving work efficiency. So, how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?
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.
Bidding.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, 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.
Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
Test method.In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least 150mm above the ground.
The detailed reason why water cannot be used to flush the hydraulic station is that doing so will corrode the oil tank in the hydraulic station, and once water is mixed in the hydraulic station, the damage to the hydraulic system is very large. Therefore, it will simply form pipeline corrosion, water vaporization,ShandongElectric elevator, and other phenomena that can cause adverse effects or results for hydraulic electric elevators. Therefore, smooth lifting and low noise.
Shandong.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.
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.
Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops
