Spring balancers work by maintaining a stable tension when the cable is pulled out or retracted
and this is achieved thanks to the tapered drum. Spring balancers are used to suspend tools
allowing workers to enjoy virtually effortless operation leading to less fatigue whilst maintaining
clutter free work spaces and production lines.
Load capacities from 0.3kg to 200kg are available.
