L type single main beam hook door type crane is suitable for ordinary loading and unloading lifting and lifting.The new Chinese steel wire rope electric hoist adopts the company's space bar support structure. The hoisting device adopts the classic "C" structure layout. The hoisting drive device drives the large diameter drum set. The coaxial three in one drive device drives both wheel sets at the same time. The rope wedge device and pulley block are suspended on the support bar. The high-strength nylon pulley block and hook block are used.

Product advantages

(1) Independent and controllable core technology

Cooperate with research institutions in various colleges and universities to develop core components, and make them completely independently, so as to achieve controllable product quality and delivery date.

(2) Modular design

Four kinds of lifting driving devices and four kinds of running driving devices can be adapted to 3~80t full series new Chinese electric hoists; The same lifting device can be used in four structures: standard clearance, low clearance, trolley running type and fixed type.

(3) Compact structure, small limit size

All series adopt large-diameter reels, which can effectively increase the lifting height and reduce the left and right limits, reduce the blind area of the crane, and provide users with greater use space.

(4) Maintenance free, energy-saving and environmental protection design concept

A. The high-precision hard tooth surface reducer has been filled with international brand lubricating oil before delivery, and it does not need to be replaced within the product life cycle.

B Maintenance free steel wire rope of international brand shall be adopted.

C High strength nylon rope guide, which becomes durable goods from wearing parts.

D. The electromagnetic disc brake has the function of automatic brake clearance compensation and maintenance free.

E The motor power is reduced by 30% compared with the traditional electric hoist.

F Through the mature application of frequency conversion positioning technology, the working efficiency is improved by more than 20%.

G The noise of the whole machine is below 70 decibels.

H The brake pad shall be asbestos free.

I The sliding friction between nylon rope guide, steel wire rope and drum will not produce metal dust, providing workers with a highly clean operating space.

(5) Intelligent, remote operation and maintenance design concept

A Safety monitor

B Big data management, cloud platform connection

C Mobile APP real-time monitoring
