Description :

　　Characteristics of hydraulic winch products

　　1) Only the distributor and valve group are located outside the drum. The hydraulic motor and shell rotation transmission device are all hidden in the drum of the winch, resulting in small axial dimensions, compact structure, and beautiful appearance; zmjt055

　　2) High starting and transmission efficiency, low energy consumption, reliable operation, and long service life;

　　3) Low noise during operation;

　　4) Good economic performance.

　　Working principle of hydraulic winch: 1. During the lifting and starting process, when the expansion brake tightens the drum, the planetary wheel cannot rotate. Under the drive of the central wheel, the planetary wheel rotates on its own, driving the internal gear ring to rotate the drum and lift the drilling tool. The instantaneous process of accelerating the load from a stationary state to a stable motion speed when the hoisting mechanism is lifted with a load is called the lifting and starting process. During lifting and starting, the direction of inertia force is the same as the direction of lifting load, which increases the tension of the steel wire rope.

　　2. During the lifting and braking process, when the brake is applied to the drum, both the drum and the internal gear are stopped from rotating. At this time, the planetary wheel rotates and revolves, achieving the braking of the drilling tool. The process of the hoisting mechanism decelerating from uniform motion braking to rest is called the hoisting braking process. Due to the direction of the inertial force generated by the deceleration motion being opposite to the direction of the lifting load, the tension of the steel wire rope is reduced.

　　Introduction to hydraulic winch products

　　Hydraulic winches, also known as hydraulic winches, are used in various lifting equipment applications. There are three types of hydraulic hoists: concealed hydraulic hoists, exposed hydraulic hoists, high-speed hydraulic hoists, low-speed hydraulic hoists. Hydraulic hoists are usually composed of hydraulic motors, control valve groups, gearboxes, drums, brackets, (clutches), rope crushers or cable cutters, installation brackets, etc.

　　Some hydraulic winches do not come with brackets and are directly composed of hydraulic motors, control valve groups, rollers, end support shafts, etc. These can be selected according to customer needs and can be widely used in conveyor tensioning devices, engineering machinery lifting machinery such as car cranes, crawler cranes, aerial work vehicles, forestry cranes, as well as port ships such as port cranes, floating ship cranes, dredgers, crane hoists, and can be used in large lifting equipment such as oil drilling rigs, offshore oil drilling platforms, pile driving machinery such as rotary drilling rigs, rock drilling rigs, core drilling rigs, static hydraulic pile drivers, etc.
