The YCM hydraulic motor has high housing strength and strong load-bearing capacity of internal dynamic components, with a wide continuous power range. The main features of the motor are as follows:
Adopts a crankshaft and a five-cylinder, five-piston mechanism with low excitation frequency, maintaining the original low-noise characteristic;
Has a large starting torque and excellent low-speed stability, enabling stable operation at very low speeds;
Utilizes a planar compensable oil distribution structure, which offers high reliability, low leakage, and convenient maintenance. The piston and plunger sleeve are sealed with sealing rings, ensuring high volumetric efficiency;
The crankshaft and connecting rod are supported by rollers, providing high mechanical efficiency; the rotation direction is reversible, and the output shaft can withstand a certain degree of radial and axial external forces.
Hydraulic Winches
Hydraulic winches, also known as hydraulic hoists, are all used in various hoisting scenarios. A hydraulic winch is generally composed of a hydraulic motor, a control valve group, a reduction gearbox, a drum, a bracket, a (clutch), a rope presser or rope arranger, a mounting bracket, and other components. Some hydraulic winches are not equipped with a bracket and are directly composed of a hydraulic motor, a control valve group, a drum, a tail support shaft, etc. These components can be customized and assembled according to customer needs.
Hydraulic winches are widely applicable to:
Belt conveyor tensioning devices;
Construction machinery hoists, such as cranes, crawler cranes, aerial work platforms, and forestry hoists;
Port and marine equipment, such as port cranes, floating cranes, crane ships, deck cranes, davits, and wheel-side hydraulic motors;
Large-scale hoisting equipment, such as oil drilling rigs, offshore oil drilling platforms;
Pile driving machinery, such as rotary drilling rigs, rock drills, core drills, and hydrostatic pile drivers.
However, hydraulic winches also have several shortcomings:
The solenoid valves and circuit equipment of wheel axle hydraulic motors are prone to problems (high sensitivity), and the larger the crane (exceeding 2.5C), the more frequent such failures occur;
Contaminated hydraulic oil tends to block the hydraulic system (resulting in unstable pressure);
If the installation is rough, oil leakage is likely to occur.
