The structure is a building hoist cage carrying ladders and counterweight, wire rope hanging in the column at the top of the fixed pulley, columns and architectural structures rigidly connected. Ladder cages electrically driven gear, with a reaction force on the fixed rack uprights, ladder cage rails for vertical movement along the column. Its columns made into a standard section length of the upper and lower sections can be interchanged according to the required height to the construction site for assembly, generally erected up lOOm, for up to 200m at high-rise building construction. Elevator can be installed by means of its own electric boom assembly at the top of the construction site can also use the crane and other lifting equipment assembly. In addition, as the ladder cage and counterweight are arranged symmetrically, so overturning moment is very small, the column passed mural firmly connected with the building structure, so reasonable and reliable force.

回复删除hello, i am student from science construction, can i know about the details of the installation process of building hoist with the attachment of pictre of every steps for my assignment? =)
回复删除Development and assembling ventures includes moving of overwhelming and huge loads for a long time. Without the assistance of materials hoist, moving and lifting those items/things will be exceptionally troublesome. Simply envision how hard and long it more likely than not been for the Egyptians to complete the Great Pyramids.
