KBA Cable Balancer — **KBA cable balancer**

KBC Chain Balancer — **KBC chain balancer**

KBA & KBC single air balancer series

Series: KBA (cable) / KBC (chain)

Knight single air balancers are used in applications that require "float" mode – allowing final positioning of the load hands-free. Lifting and lowering are faster than with a conventional hoist, allowing fine adjustment ("feathering") when positioning the load. The ergonomic control handle has color-coded thumb levers.

When selecting an air balancer, it is recommended that the working load use only 80% of the rated capacity to compensate for normal fluctuations in the plant air system. The working load includes the part weight and the weight of the handling tooling. Balancers are designed for 100 psi [6.8 bar].

Calculation: Plant air 60 psi, 350 lbs model, 80% factor → (0.60 × 350) × 0.80 = 168 lbs actual working capacity.
