Motor type CA 50 and CA 70
Fixed shaft - torque arm mounted motor, viscosity 40/250 cSt, speed 100 rpm.
Torque arm is mounted at a = 0 mm on the motor.
Note: When Bracket mounted motor or higher external load, please contact Hägg lunds representative.
Permissible external loads
- The bracket must be designed so it does not give
extra external forces to the motor.
Motor mounted in winch - reaction forces.
