Abstract

The invention discloses a controllable synchronous lifting device, belonging to a middle or small-size crane, comprising a motor, a transmission mechanism connected with the motor and a winding drum connected with the other end of the transmission mechanism. The controllable synchronous lifting device is characterized in that the transmission mechanism is provided with a sensor for counting the transmission mechanism; and the sensor is connected with a display alarming device. The controllable synchronous lifting device can promptly reflect the work conditions.

Description

Controllable synchronous lifting equipment technical field The invention relates to a medium-sized lifting device, in particular to a controllable synchronous lifting device. Background technique Electric hoists are often used on single-hanging rails, jib cranes and manual single-beam cranes. Because of their simple structure, convenient manufacture and maintenance, good interchangeability, and easy operation, they are widely used in factories. The electric hoist is mainly composed of a motor, a gear reducer, a reel, and a brake. The output of the electrode output shaft is decelerated by the gear reducer to drive the reel, so that the starting rope on the reel is rolled up or lowered to achieve the purpose of lifting. It often happens that multiple electric hoists are lifting at the same time, and multiple electric hoists need to act in unison. At this time, multiple electric hoists are required to be synchronized. The disadvantage of the prior art is that the electric ho...
