Main Structural Features of Drum Electric Winch, Hydraulic Anchor Drum Winch The JM construction windlasses are composed of a base, motor, elastic coupling, hydraulic brake, enclosed triple-reduction gear box, reel, brackets, and an electrical control cabinet. When the motor starts, it drives the reduction gear box through the elastic coupling, which in turn rotates the reel. All motors are YZR-series products that comply with national standards (GB). The reel's operation or braking is controlled by the hydraulic brake, ensuring synchronized performance with the motor for safe and reliable stopping when power is cut off. Parameters Main Advantages Applications Our winches are driven by gear reducers. They are primarily used for lifting, pulling, unloading, and towing heavy loads. These units are ideal for construction, installation projects, mining areas, factories, and more. Their simple structure and excellent performance make them versatile for various applications.

The base is constructed from channel steel, providing a sturdy structure with ground bolt holes and lifting rings. A shaft passes through the drum, which is made from welded steel plates or seamless steel pipes mounted on the support shelf.
Designed for use in various hoisting machinery, these motors offer high overload capacity and mechanical strength, making them suitable for devices requiring frequent starting, braking, or operating under vibration and impact conditions.
Electro-hydraulic block brakes use pullers as driver units, offering fast response, safety, ease of maintenance, low noise, long lifespan, energy efficiency, and high operational efficiency.
Three-stage speed reduction system using high-strength gears, large load capacity, and low noise. The input shaft connects to the motor, while the output shaft drives the drum for forward and reverse rotation.
Includes a push-button controller for starting, speed adjustment, and reversing. It features forward, stop, reverse, emergency stop functions, along with ammeter and indicator lights.
Fault

Fail to Start
Damaged contactor contacts, loose wires, blown fuse, thermal relay action, or low voltage
Grind contacts, reconnect wires, replace fuse, adjust thermal relay
Fail to Stop After Start
Damaged switch contacts, poor brake wiring
Grind contacts, correct wiring
Direction Mismatch
Incorrect power phase sequence
Cut power, correct phase sequence
Motor runs but stops when button is released
Auxiliary contact damage, failed self-locking
Grind auxiliary contact, check and rewire self-locking circuit

PVC molecular chain is a winding structure and contains polar groups of chlorine atoms, which makes the force between molecules large. This structure improves the rigidity, hardness and mechanics of PVC processed products, and endows them with excellent flame retardant properties.
There are chlorine atoms and hydrogen atoms between two adjacent carbon atoms on the main chain of PVC Resin, which makes PVC easy to degrade under the action of light and heat to form hydrogen chloride (HCl) gas.
Properties of PVC:
General performance:
PVC is a white powder with a relative density of 1.35~1.45 (g/cc). The hardness of the processed products can be greatly different from that of the products with different hardness by adding the amount of Plasticizer during processing.
Mechanical properties:
The tensile strength of PVC increases with the increase of polymerization degree, but the amount of plasticizer added in PVC has a great impact on the mechanical properties. Generally speaking, the mechanical properties decline with the increase of plasticizer content, but the elongation at break will increase.
Thermal performance:
The glass transfer point temperature of PVC is 80~86 ℃. The PVC resin starts to decompose at 140 ℃ to produce HCl, which accelerates rapidly at 180 ℃. Generally, the melting temperature of PVC is 160 ℃.
Electrical performance:
PVC is an excellent electrical insulation. The volume impedance is higher than 10 λ 14, but the volume impedance is easily affected by the type of processing additives and additives.
Chemical resistance:
PVC can resist most inorganic acids (except fuming sulfuric acid and concentrated nitric acid), alkalis, most organic solvents (ethanol, gasoline and mineral oil) and inorganic salts, and is suitable for chemical resistant materials. However, PVC is easy to swell or dissolve in esters, ketones, aromatic hydrocarbons and halohydrocarbons, and the best solvents are tetrahydrofuran and nitrobenzene.
Product benefits
PVC quality is stable, PVC supply is stable, and it complies with international environmental protection regulations.
