Abstract

The present invention provides a pullback weight of an elevator, capable of taking account of safety and treatment facility of balance blocks without reducing of their total weight and load. The balance block is formed by filling concrete (22) in an iron frame (21) to solidify, and the iron frame (21) is provided with a hollow part (24) as a handle.

Description

technical field [0001] The present invention relates to a counterweight of an elevator, in particular to a counterweight of an elevator capable of safely loading a counterweight. Background technique [0002] In the elevator, the load of the hoist is reduced by making the counterweight balance the weight of the car. Conventional counterweights balance the weight of the car by mounting a necessary number of counterweights in the counterweight frame. [0003] in Figure 11 The counterweight described in Patent Document 1 is shown as an example of the prior art counterweight. [0004] This counterweight has a pair of frames 1 arranged along guide rails, a plurality of counterweights 2 held on the frames 1 at both ends, through bolts 3 provided to penetrate these counterweights 2, and these through bolts 3 and the main counterweight are connected to each other. Heavy 2 is fixed into an integral nut 4. In addition, 5 represents a suspension rope, and 6 represents a guide shoe ...
