The SP-3050 Manual Push/Pull – Electric Lift & Clamp Shaft Puller consists of a wheeled base with a support head and a shaft clamp. The operator uses controls for electric motor to raise and lower the support head. The fail-safe electric clamp securely grabs the shaft journal, allowing for easy retraction and insertion. All movement is manual push/pull – the unit has been redesigned to be lighter and easier to maneuver.
