Set of hooks in freight elevator machine room. At the center of the shaft at the center of the engine room, a section of 250 mmx250mm frame beam is set. The center of the beam has been transferred to the hook of the design height and position of the embedded host. The load-carrying capacity of the hook should be up to 3,000 N and a diameter of 25 mm is available. The rebar is bent into an arc and welded to the beam with the main reinforcement.
Bottom treatment. The bottom of the wellbore should be greater than or equal to a buffer layer of 500 mm. The lien of the buffer space, if it is too large, will affect the elevator to a certain extent. Therefore, the processing of extra space should be performed before the cargo elevator is installed. The crushed stone is compacted to make 40 mm thick fine stone concrete.
Treatment of the inner wall of the wellbore. Standard brickwork, some units or project managers, in order to pursue aesthetics, use cement mortar to smooth or even putty on the inner wall of the well.
During the operation of the elevator, the well wall is flat and the echo has a large impact, which seriously affects the normal operation of the elevator. Therefore, it is better not to do any treatment and maintenance of the inner wall of the well.
