Air Motor unit for Winches

Product catalog summary
Overview
The document describes a braked air motor unit designed by GLOBE for winch and hoist applications. This unit includes a robust vane motor, a fail-safe BN brake, and a proportional directional control valve. The system is designed to operate under harsh conditions and complies with European Standard NEN-EN 13463-1 for non-electrical equipment in explosive atmospheres (ATEX GROUP II cat 2 GDc T4).

Specifications
  • Vane Motor: Features include no pins or springs, guaranteed positive start-up, adjustable torque and speed, ability to stall under load without damage, high lifespan, low cost, reversible operation, and oil-less operation capability.
  • BN Brake: Advantages include use in static applications, field serviceability, easy flange connection, low maintenance, compact design, interchangeability, and robust housing for harsh environments.
  • Proportional Control Valve: Available as remote (RCV) or hand control (HCV), features include a robust cast steel body, high flow design, frictionless spool and sleeve, and accurate proportional control. Valves can be supplied with equal or biased power spools, suitable for hoisting applications.

Operation and Control
The motor unit is designed to ensure the motor is pressurized before the brake is released. The proportional valve controls the motor's direction and speed, with options for remote or hand control. The system is designed to prevent overspeed in lowering directions by using biased power spools.

Performance and Maintenance
  • Maximum continuous speed varies by model, with a range from 2400 to 4000 rpm.
  • Airline filtration and lubrication require 64-micron filtration or better, with specific lubricator drop rates for continuous and intermittent operations.
  • Maximum overhung force and axial load recommendations are provided to ensure optimal performance.
  • The motor is reversible and can operate in all positions, with a temperature range of -20°C to +80°C.

Graphical Data
The document includes various graphs illustrating torque-speed, power-speed, torque-pressure, and air consumption-speed relationships for different models. These graphs help in understanding the performance characteristics under different operational pressures.

Air Motor unit for Winches-2

Vane Motor + BN Brake + HCV/RCV Application GLOBE has developed specially for winch and hoist applications a braked air motor set. The unit has a robust GLOBE vane motor with an fail safe BN brake and a proportional directional control valve. The vane motor is of ridged design and very good for harsh conditions. The BN brake is a spring loaded, air release failsafe brake. The holding torque is 1,5 to 2 time the maximum torque of the motor. On top of the motor a proportional control valve is mounted. It can be a proportional remote control valve of a proportional hand control valve. The proportional...
