Reeved Balancer

Air Balancers are used in applications where a "float" condition is beneficial. Float allows for the hands-free final positioning of an object. The up/down speed of a air balancer is quicker when compared to a hoist and allows for a "feathering" operation when locating the load. The pendant controls are ergonomically designed incorporating color coded thumb levers.

Reeving a air balancer increases the mechanical advantage of the product. Additionally the reeve and pulley offers a second suspension point which gives greater stability to the load. Reeved air balancers come standard with a 1 ton spring lock bail hook.

• Optional external retract control imparts a controlled condition to the spooling of the cable. By adjusting the pressure of the shock, the spool will only be allowed to move in a chosen maximum speed. This option works well with heavy parts and light end effectors once the heavy part is off loaded, the light end effector does not move at an accelerated rate of speed.
• Optional high relieving and feathertouch controls help to exhaust air quicker on heavier loads and provide a way to operate the tool without a pendant.
• Hands free operations can include a dual balance control which is typically used when the lift assist includes the part and does not include the part. Also, a single balance control is offered that is typically used when the load is not removed from the tooling.
• Knight air balancers do not require lubricated air.
• Knight incorporates a standard internal centrifugal brake to insure that any runaway load comes to an immediate complete halt.
• Knight air balancers are CE Certified.
• Knight air balancers have a range of use up to 2,800 lbs [1,270.1 kg] (Tandem Reeved)
• Standard travels are available up to 110 in. [279 cm].
• Knight offers the use of chain instead of cable. Chain is more durable when balancing weights in excess of 250 lbs [113.4 kg] and / or high cycle times are encountered. The use of cable under these conditions has a greater tendency to fray or "birdcage" requiring a more specific PM program.
• Suspension kits are available for most competitive workstation crane systems as well as I-beam / patented track.

When specifying a air balancer, it is recommended to use 80% of the rated load to determine your load capacity. This approach compensates for the normal fluctuations within the plant compressed air supply. Balancers are rated at 100 psi therefore use the following example to calculate exact load capability.
