Problems solved by technology

[0002] The existing electric hoist is equipped with a reel and uses a pulley block. When the crane is in use, if the lifting height is high, the reel needs to be very long to meet the needs of use, which causes a lot of inconvenience to the user and affects the Production efficiency increases the production cost. At the same time, because the angle between the reel and the pulley block is too large during lifting, it is often pulled by a large distance, which will greatly reduce the service life of the electric hoist, and there is a greater safety hazard.

Embodiment Construction

[0006] Specifically describe embodiment in conjunction with accompanying drawing, the present invention is made up of two reels, a block of pulleys, and two reels 1 are reversely installed, and are arranged in parallel, and wire rope 7 passes through the block of pulleys that is made up of fixed pulley 4 and movable pulley 5 and two reels Connect separately. The pulley block consists of a fixed pulley and a movable pulley. The pulley block consists of at least 1 static pulley and 2 movable pulleys. A suspension hook 6 device is arranged on the movable pulley of the pulley block. Static pulley is installed in running device 2 bottoms, and running device runs on the track 3 of support, and reel can be installed on support 8 tops or below the support. When the two reels run synchronously, each drives the steel wire rope and drives the hook device through the pulley block to realize the task of lifting heavy objects. Compared with the original electric hoist, under the same ree...

Abstract

The invention discloses an overlong motor hoist, which comprises two reels and a pulley group; wherein, two reels are reversely mounted and parallel arrayed; wire ropes are respectively connected with two reels through the pulley group; the pulley group comprises a fixed pulley and a movable pulley; the pulley group at least comprises a static pulley and two movable pulleys; hooks are arranged on the lower part of the two movable pulleys of the pulley group; and the reel can be mounted above a bracket or under a bracket. The invention has the advantages of convenient use, safety and reliability, and increases the hoisting height of the motor hoist.

Description

Technical field: [0001] The invention relates to a crane, in particular to a super-long electric hoist capable of lifting a high height. Background technique: [0002] The existing electric hoist is equipped with a reel and uses a pulley block. When the crane is in use, if the lifting height is high, the reel needs to be very long to meet the needs of use, which causes a lot of inconvenience to the user and affects the Production efficiency increases the production cost. At the same time, because the angle between the reel and the pulley block is too large during lifting, it is often pulled by a large distance, which will greatly reduce the service life of the electric hoist, and there is a greater safety hazard. . Invention content: [0003] The purpose of the present invention is to provide a super-long electric hoist with simple structure and convenient use. The task of the present invention is accomplished in this way. The super-long electric hoist includes two drums...
