Foretell electric block is located the support right side, and the track below, the peak height does not exceed the track, compares in the electric block of installing in the track top, has saved the space of top, has increased the space of lifting by crane, and electric block can dismantle removable, installs simple and conveniently.

The weight box and the electric hoist are distributed on two sides of the track, the weight of the weight box and the electric hoist are the same as that of the electric hoist, the highest point height does not exceed the track, the weight box and the electric hoist are balanced on two sides of the track, the weight box and the electric hoist belong to a main body part and cannot be detached, and the weight box and the electric hoist can be adjusted according to different weights of the electric hoist.

The bracket is positioned below the bracket, is connected with the electric hoist and the weight box, adopts No. 45 steel, is used for connecting the left part and the right part, and is erected on the track to connect the left part and the right part into a whole.

The group of fixed pulleys are positioned above the side of the counterweight box and used for changing the tension direction, and the fixed pulleys cannot be disassembled.

The beneficial effects of the utility model are that, utilize the connection structure of the left and right sides, the required subassembly of reduction increases the weight box, makes the structure simpler, because the main component all distributes in the track both sides, make full use of the space of track both sides and below, makes the structure safety and stability more, and electric block has bigger space of lifting by crane.

Drawings

The invention will be further described with reference to the accompanying drawings:

Detailed Description

The invention is described in further detail below with reference to the following figures and embodiments:

[ example 1 ]

The low-clearance electric hoist comprises an electric hoist 1, a weight box 4, a support 2, a running track 5, a group of fixed pulleys 3, a steel wire rope 8, a lifting hook 7 and a group of running wheels 6. As shown in fig. 1, the electric hoist 1 is located on the right side of the support 2, below the rail 5, the weight box 4 is located on the left side of the support 2, below the rail 5, the support 2 is located under the rail 5, the electric hoist 1 and the weight box 4 are connected, the operation rail 5 is located above the support 2, and the group of fixed pulleys 3 is fixed on the left lower side of the support 2.
