The Foot Mounted Posistop Brake is similar in design to the Posidyne Clutch Brake incorporating many of the same features including multiple friction surfaces, lubrication and cooling by recirculating fluid.
The Posistop Foot Mounted units are designed to be connected to the load by coupling or chain or belt drive.
Six standard sizes are available with torque ratings up to 1800 Lb. Ft. The Positorq series of tension brakes can also be furnished as stopping brakes with torque ratings up to 200,000 Lb. Ft.
These brakes can be designed as air/hydraulic set, spring release which allows control of the braking torque, or spring set air/hydraulic release which does not allow adjustment of the braking torque. The spring set advantage is if the control fails the brake will set.
There are three actuation types or control logics to select from:
S = Pressure Set Brake / Spring Release
A = Medium Spring Set Brake / Pressure Release
B = Heavy Spring Set Brake / Pressure Release
The spring set units are preset at the factory and are not adjustable. The air set units are adjustable over the full range.
