Double Purchase Pulley Actuators

Double Purchase pulley actuators double stroke lengths up to 120 feet (36.5 m) without increasing space requirements.

The Tolomatic double purchase pulley actuator can double the stroke and velocity of a double acting cable cylinder with considerable cost-saving advantages. Double purchase pulley actuators can also be operated when placed away from hostile environments where motion is required.
