Zero Gravity Balancers with Fall Protection Device as a Standard Feature
Zero gravity balancers from Carl Stahl Kromer keep your load reliably and safely suspended at any height. You just pull the suspended tool to the position of your choice and release it. As no retraction force acts upon the tool, these balancers are ideal for delicate, high-precision tasks.
A particularly innovative development from Carl Stahl Kromer is the double-cable balancer model 7248. In addition to enhanced wear protection, the second cable functions as an integrated fall protection device in the event of cable breakage: Should one cable fail, the working load is immediately held by the second cable. This genuine Carl Stahl Kromer feature ensures the uncommonly high durability and increased safety of these zero gravity balancers.
Just like the spring balancers (retractors), some Carl Stahl Kromer zero gravity balancers are optionally available with a ratchet lock allowing you to arrest the retracting load at predefined positions. The arresting mechanism is automatically triggered if the load is moved back slowly. Fast retraction, in contrast, leaves the ratchet lock inactive.
All Carl Stahl Kromer zero gravity balancers have been life-tested and satisfy the DIN 15112 requirements. They also comply with the EC legislation on CE-marking and bear the „GS“ mark as a safety-tested product.
