SQ manual crane is an important lifting equipment, which is characterized by the use of manual power for operation.
Structural composition
SQ manual crane is mainly composed of bridge, truck transmission mechanism, lifting car and other main parts. Among them, the bridge is composed of a main beam and two end beams, the main beam is usually I-beam, and the end beam is welded by two channel steel. The driving and lifting operation of large and small cars are achieved by manual chain drive.
Working principle
Manual lifting mainly uses the lever principle, rolling or rotating principle and lever principle. Through tools such as handles or levers, human muscle strength is transmitted to the lifting device. Lifting devices increase torque by increasing the length of the lever arm, thus providing greater lifting capacity. At the same time, the use of rollers, balls or rotating accessories to reduce the friction of the lifting object, so that lifting becomes easier.
Application field
SQ manual cranes are mainly used in factories, mines, docks, power station warehouses, workshops and other places where there is no power supply or work is not busy, for fixed straddle loading and unloading, lifting heavy objects or maintenance equipment and other tasks.

At the same time, its span can also be selected between 10 and 17 meters according to specific needs. This kind of crane is simple to operate, strong adaptability, and the requirements for the working environment are not high, such as the ambient temperature is not lower than -25℃ conditions can work normally.
SQ manual crane has many advantages, and it is still necessary to pay attention to operation specifications and safety matters during use to ensure the safety of personnel and equipment.
