Construction elevator installation steps

- Apr 08, 2020-

01 Install the chassis and foundation section

First clean the concrete foundation, install the base frame, install the base section on the base frame, and add three standard sections, then measure the verticality of the guide rail, the required deviation is ≤1 / 1000; then tighten the anchor bolts.

02 Install the hanging cage

Use the lifting equipment to accurately place the hanging cage from above the standard section, coarsely adjust the lower balance wheel and lateral rollers of the hanging cage, install the guardrail on the top of the hanging cage, and adjust the mechanical door lock of each door.

03 Install the drive plate

Use a lifting device to accurately position the drive plate from above the standard section, and adjust the rollers roughly; use a pin to connect the drive plate and the cage.

Install boom

04Put the boom into the installation hole on the top of the cage and use it after connecting to the power supply.

Install counterweight system

05 (For lifts with counterweight) First install the buffer spring at the counterweight position of the chassis; lift the counterweight with lifting equipment, put it into the counterweight track from the top of the rail frame; adjust the roller clearance.

06 Install the rail bracket

Use the installation boom to lift a standard section (note that the end with the tapered sleeve is down), put it on the top of the cage and stabilize it, start the cage upwards, so that the top of the cage is about 300mm away from the top of the rail, and stop. ! Then use the boom to lift the standard section slightly above the top of the guide rail, turn the boom to align the standard section with the top of the guide rail, lower it, and tighten the connecting bolts. Repeat so, step by step to raise the guide rail. Install the wall bracket in time when you reach the location where the wall bracket is attached.

07 Install the attached wall bracket

First install the front attachment rod on the column guide rail, and then install the wall bracket; then adjust the verticality and tighten the bolts; finally start the hanging cage slowly and check whether it touches the wall bracket.

Adjust the rope card

08 Skywheel and counterweight wire rope installation When the guide rail is installed to the required height, the elevator with counterweight should install the skywheel on the top and suspend the counterweight with a steel rope. First hang the skywheel to the top of the cage, after the cage rises to the top, and then to the top of the rail frame, install the bolts; then wear the counterweight wire rope and put on the rope clamp. Note: There should be more than 3 rope clips, with an interval of more than 100mm, and the bottom of the rope clip is on the stress side of the steel rope.

Adjust the length of counterweight wire rope

09 Adjust the length of the counterweight wire rope so that when the cage reaches the maximum height, the distance between the counterweight and the ground ≥550mm

10 Install the cable system

The lifting height of the elevator is high, and the power drive device is on the hanging cage, so the cable is also important to retract. The cable system has a guide system with a cable trolley, and a guide system without a cable trolley, which externally connects the cable. Either way, it must be coordinated by a dedicated electrician for installation.

11 Inspection after installation

After installation, it must be checked before operation. The main points of inspection are: the tightening of each fastener, whether the action of each limit switch and electromechanical interlocking device is correct.
