Overhead Mounted Vertical Mast Arm

Knight’s ATA4000 Overhead Mounted Vertical Mast Arm has fixed control handles that improve ergonomics by eliminating the need for an operator to bend or reach. It is typically used in applications that require significant up and down travel and precision placement. The arm can either rotate 360 degrees or can be fixed mounted for the operator.

Vertical Mast Arms are available with

Heavy Duty Articulating Pneumatic Arm

Knight’s AAA9000 Overhead and Floor Mounted Heavy Duty Articulating Pneumatic Arms are parallelogram arms used to lift, rotate, balance, and move product from conveyors, dunnage, assembly lines and more. They utilize twin cylinders in the rear of the arm to achieve greater lifting capacity while reducing the overall mass of the tool. This minimizes operator fatigue by absorbing torque reaction and

Medium Duty Articulating Pneumatic Arm

Knight’s AAA6000 Overhead and Floor Mounted Medium Duty Articulating Arm is a parallelogram arm used to lift, rotate, balance, and move product from conveyors, dunnage, assembly lines and more. AAA6000 Arms utilize twin cylinders to achieve greater lifting capacity, and therefore reduce operator fatigue by absorbing torque reaction and helping to lift and manipulate the product effortlessly.

The Overhead

Torque Tubes

Torque Tubes
Knight’s Torque Tubes are designed to reduce operator fatigue by absorbing torque reaction produced by assembly tools while balancing the tool weight. Torque Tubes use a pneumatic cylinder or spring balancer to achieve zero gravity balancing. Each pneumatic cylinder is supplied with single balance control.

Torque Tubes are most commonly used as tool holders by incorporating Knight’s ASA9518

Servo Systems

Servo Hoist Systems
Knight Servo Hoist Systems are user-friendly, Intelligent Assist Devices (IAD) that provide controlled transfers of workloads by enhancing the precision and speed needed for the application. As an extension of an operator’s natural movement, this technology greatly improves the accuracy and repeatability of the application. Additionally, Knight has integrated their servo systems with the advancing technology of Industry 4.0.
