Installation of the bottom three-section rail frame (standard section) After assembling the bottom three standard sections on the ground, use the tower crane to hang on the foundation frame interface, adjust the verticality (1/1000) with the Weiyi instrument, and tighten the connection. Bolt, tightening torque is 350N.M. Construction elevator parts quotation Construction elevator parts offer After the elevator base and foundation section are installed, the outer cage can be assembled and the verticality of the outer cage door frame (1/1000) can be adjusted to make the outer cage door open and close flexible.

Lift the drive unit with a tower crane, position it from above the standard section, align the drive unit with the connecting lug of the cage, thread the pin and fix it (the elevator with the overloaded device penetrates the sensor pin and The stop groove is upward and the fixing plate is attached). After the drive unit is hoisted in place, the performance of the motor brake device is restored and the cage guardrail is installed.
