Q:How does the construction elevator add up: With the popularity of construction lifter to use, but knowledge of the user of this kind of special equipment, and makes the construction lifter in use process safety accident frequency is higher and higher, it is necessary to everyone together to discuss how to eliminate the safety hidden trouble as possible. This paper makes a concrete analysis on the use of the construction elevator during the use of the elevator.

Q:How to adjust the weight limit of the construction elevator: You're not going to be without a master You still look at the instructions

Q:How does the driver of the construction elevator do the search for a sudden power failure: When the elevator in the operation of the midway stop due to power outages or other reasons, the manual can be decreased, the end of a motor brake electromagnet manual release slowly shake handshandle pull outward, slowly slide down the ladder cage, ladder cage fall shall not exceed the rated speed, manually drop must be conducted by professional maintenance personnel.

Q:Excuse me: what is the meaning of heavy weight in the construction elevator?: This is very nice! Learn more! Thank you for your dedication...

Q:How is the construction elevator installed: Construction elevator installation 1) the location of the elevator depends on the condition of the site and the equipment, so as far as possible, stay away from the overhead line and keep the safe distance specified. When the elevator is running, there is a lot of danger and should be avoided. 2) the order of installation is: 3) place the chassis on the base and the base pre-buried bolt, and the platform is placed on the chassis, and the basket is placed in the middle of the chassis. 4) to install the standard section, each installation of two standard sections (usually less than 8m) to be temporarily fixed. The wire rope shall be used for the use of the temporary cable, and the joints and supporting points shall be bolted and not tied with the lead wire. 5) the installation should alternate between the two columns. Node bolt specification must according to the aperture matching, not packing, found that the aperture position at the time, can not arbitrarily expanding, more can't to lead wire bundle, instead to avoid loose node deformation. 6) when installing the standard section, pay attention to the vertical degree of the guide, and the line of the guide line should not appear in the line of folding and too big clearance to prevent the collision from running. 7) when construction site conditions permit, it can be assembled on the ground and then hoisted on the whole to reduce the height of the work. Due to the design of the frame, the stress condition of the construction is only considered, so before the whole moving up, the counter can be temporarily strengthened to enhance the bending capacity of the nodes.
