To work precisely, without fatigue and over long periods of time
Medium-Duty Zero Gravity Balancer with automatic ratchet lock
Kromer balancers 7231. is eminently suited to high cable extension rates, even under difficult conditions. The load ranges are between 16,0 and 21,0kg. The available 2,0 m cable extension range allows suspended loads to be precisely and delicately guided.
In spite of balancer 7231. light-weight design, the balancer 7231. easily masters even rough jobs involving a high cable extension rate in daily operation. Whether balancer is used for simple weight compensation or for extreme applications such as retaining robot hose/cables packages, the 7231. type series meets any requirements encountered within its load range. A cable extension of 2,0 m enables users to cover larger working areas as well. Load setting is done conveniently via an endless screw allowing continuous adjustment.
Kromer balancer models come with a whole range of safety components as standard features that include a fall prevention device and a spring fracture safeguard in addition to a safety suspension and a screw-type spring hook for load suspension. As the cable is continuously adjustable in length and the working range can also be infinitely adjusted (reduced) via the cable clamp, the unit can be easily and optimally adapted to specific working needs.
