Yale RPY & RPES Universal workshop presses

Capacity 10 - 200 t
For all repair and assembly jobs.
According to European standards, all Yale workshop presses can be used without any additional protection devices as the piston speed is below 10 mm/s.
For special applications additional safety equipment (e.g. protection grid or two-hand-safety-control) can be offered on request.

Features and Benefits

Applications
• Pressing and removing of bolts, shafts, bearings.
