Balancer for moving loads has linear guide on foundation frame supporting balance arm whose balancer arm engagement part engages positively in traction

摘要

The balancer has a linear guide (2) mounted on a foundation frame (1) and supporting a displaceable straight, curved, angled or bendable balance arm (5) on which a variable useful load engages. A balancer arm engagement part (6) mounted on the balance arm engages with keyed engagement in a traction means (7) which is connected to a servo motor in which a turning angle transmitter is provided which is connected to a special microprocessor control and regulator. Independent claim describes method for controlling balancer whereby in the event of an energy failure a mechanically, pneumatically or electrically operating blocking device locks the balance in the corresponding position.
