Product catalog summary

Main Components

Hydraulic Motor: Available in orbit, gear, or optional piston motor configurations.
Negative Static Multi Disc Brake: Automatically operates with pressurized oil and re-applies with springs when pressure is released.
Planetary Reduction Stage: Features a compact design with optimized gear ratios for line speed and pull performance.
Brake Control Valve: Provides dynamic braking and is mounted directly onto the motor for safety.
Drum and Winch Frame: Constructed from structural steel or ductile iron for durability.

Technical Data and Dimensions

Line pull capacities range from 890 lbs to 10,900 lbs, depending on model and rope layer.
Line speed varies with GPM and rope diameter, with specific speeds for each model.
Rope storage capacity varies by diameter and layer, with some non-compliance to ANSI spec. B30.7.
Standard hoisting drum rotation is clockwise, with counterclockwise available on request.
Load control during lowering is managed by an overcentre brake valve.
Static brake torque varies by model, with a maximum back pressure of 72.5 PSI.
Gear lubrication is achieved through a splash oil bath.
Safety note: Not designed for lifting people.

Performance Information

Specific performance ratios, displacement, and PSI ratings for each model.
Detailed line pull and speed data based on rope diameter and layer.

General Recommendations

Maintain at least 3-4 wraps of cable on the drum for safety.
Specifications are subject to change without notice.

Technical Specifications

Maximum back pressure: 72.5 PSI.
Gear lubrication via splash oil bath using hydraulic oil.
Standard drum rotation is clockwise or counterclockwise.
Automatic operation of the internal negative static multi-disc brake.
Specifications subject to change without notice.

Performance Information

Models with different performance ratios (e.g., 15.26:1, 21:1, 64.1:1).
Line pull capacity from 5100 lbs to 15000 lbs.
Line speed varies with GPM input, from 76 fpm to 438 fpm.
Rope diameter and storage capacity vary by model.

Installation and Operation Guidelines

Mount on a surface of adequate thickness and flatness.
Select line sizes proportional to oil flow.
Use open center control valves.
Proper hydraulic oil filtration required.
Not intended for lifting people.
Pressure relief valve set 435 PSI over working pressure.

Safety and Maintenance

Keep at least 4 wraps of cable on the drum for safety.
Load control by overcentre brake valve.
Follow technical data in DINAMIC OIL documentation.
Non-adherence to specifications voids warranty.

Hydraulic Winches

Open the catalog to page 1

MAIN COMPONENTS 1 Hydraulic Motor: Orbit, gear or optional piston motor on some models. 2 Negative Static Multi Disc Brake: Is connected to the motor shaft and winch body. Pressurized oil from the hydraulic circuit opens the brake, and the springs automatically re-apply when pressured is released. The brake is automatically controlled by the hydraulic brake valve and is opened and closed by starting and stopping the motor. 3 Planetary Reduction Stage: The overall dimensional size of the winch is very compact. Gear ratios of each model are selected to maximize line speed and line pull performance....
