Knight Global Single EX Chain External Retract Control Pneumatic Balancer Series - KG KBC-EX
The external safety retract control is an adjustable safety feature that regulates the balancer's speed of vertical travel. If a load is lost, the cable or chain will slowly retract into the balancer versus suddenly accelerating upward. The hydraulic shocks from the external retract control put resistance on the thrust bearing allowing for a slow and controlled retraction.
The external retract control balancer series are typically used:
- If the fixture that is attached to the balancer is a light hook picking up a heavy part
- If a part has the tendency to get stuck in the dunnage
In both these applications the retract will control the cable/chain from suddenly accelerating up. When specifying a pneumatic balancer, it is recommended for working loads to use 80% of the operating capacity for lifting applications. This approach compensates for the normal fluctuations within the plant compressed air supply. Working loads include part weight and handling device weight. Balancers are rated at 100 psi [6.8bar] therefore use the following example to calculate exact operating capability.
Formula for pneumatic balancer sizing: Example - plant air 60 psi, 350 air balancer, 80% load capability (0.60 air supply x 350 lbs. = 210 x .80 = 168 lbs. operating capability).
Features:
- CE Compliant
- Hands-Free Operation
- Standard "Float" Mode
- Internal Centrifugal Retract Control
- Requires Non-Lubricated Clean/Dry Air
- Knight recommends the use of high performance, extreme pressure, anti-wear food grade penetrating oil (Lubriplate 1241 Recommended) that penetrates and lubricates cable. For chain (SAE 50 to 90 EP oil or equivalent machine/gear oil) is Recommended
Benefits:
- Optional Limit Switches
- Optional High Relieving and Feather touch Controls
- Multiple Suspension Kits Available
