The winch is a device that drives the drum and winding rope by human or mechanical power to complete the traction work. Heavy objects can be lifted vertically, horizontally or obliquely. Winch is divided into manual winch and electric winch. Now it is mainly electric winch. The electric hoist is composed of motor, coupling, brake, gearbox and drum, which are jointly installed on the frame. In the case of large lifting height and loading and unloading capacity and frequent work, the speed regulation performance is good, which can make the empty hook drop quickly. For materials installed in place or sensitive, it can use a small speed.
Hoists are mainly divided into manual hoists and electric hoists.
The main differences between the two are: manual manual manual control of clutch to realize rapid rope release, and the speed of electric rope winding and rope release is the same; In the absence of power supply, the manual winch can be powered by diesel engine, while the electric winch cannot.
Slow speed winch: winch with rated speed of steel wire rope on drum of about 7 ~ 12m / min.
Fast Winch: the winch with the rated speed of steel wire rope on the drum of about 30m / min.
Electric winch: a winch that uses the motor as the power to rotate the drum through the driving device.
Speed regulating Winch: a winch whose speed control can be adjusted.
Hand hoist: a hoist that uses manpower as power and rotates the drum through the driving device.
Large tonnage non-standard Winch: mainly used for hoisting, pulling, unloading, pushing and dragging heavy objects. Such as the installation and after-sales of various large and medium-sized concrete, steel structure and mechanical equipment.
Principle of Winch:
The winch converts electric energy into mechanical energy through the motor, that is, the rotor of the motor rotates and outputs, and then drives the drum to rotate after deceleration through triangular belt, shaft and gear. The drum winds the steel wire rope and passes through the pulley block to make the crane hook lift or drop the load, so as to complete the vertical transportation, loading and unloading of the load.
Scope of Winch: it is mainly used for hoisting, pulling, unloading, pushing and dragging heavy objects. It is suitable for material lifting or horizontal dragging in construction, bridge, metallurgy, mining and other enterprise construction sites, water conservancy projects, forestry, mines, wharfs, etc. it is used as winch in material lifting and large hoisting projects to drag various materials and equipment.
