Completely pneumatic. With simple controls and only a few moving parts, RMT Presses require minimum maintenance to assure years of reliable performanceand high productivity.

Guard actuation is fast, automatic and operator friendlywith the die space completely surrounded during the ram cycle. Lowering the guard advances the ram,releasing the guard automatically retracts the ram.Guard meets OSHA requirements.

Economical air operated RMT presses are powered by double acting “air saver” cylinders providing fast,dependable operation and easy servicing. Pneumaticvalves are mounted safely inside the cover to assureclean and quiet operation. There is no motor, clutch or brake to maintain.

Quality construction, safe operation and trouble free performance

Powerful toggle action generates force like a flywheel press... providingmaximum tonnage near bottom of the stroke

Low-cost air operationreduces maintenance

Ten rugged models from 3 ton to 24 ton assures a press that’s right for your every application

The ram is guided in adjustable VEE gibs for precise diealignment. High repeat accuracy is provided by positivestops at each end of the stroke. Ample ram adjustmentpermits fast, accurate final depth settings. Dies are bolted to the ram and the T-slotted bed.

RMT presses are entirely air operated, with the toggleaction powered by a unique adjustable stroke air cylinder.Shop line pressure is multiplied to obtain up to 24 tons ofram force. Toggle design facilitates easy adjustment ofstroke length, depth and speed to match the operation.Air line mufflers provide quiet operation.

Heavy cast iron bodies are built to resist deflection andabsorb shock. Close tolerance shafts and bronze bushingsassure accurate and consistent stroke depth and long toollife. Working components are mounted within the frameand protected by a durable sound absorbing fiberglasscover that encloses all moving parts.

The linkage can be moved and reset by hand by shifting the airvalve to “Off” to bleed air from the system. Optional controls arequickly and easily connected to the convenient external ports onthe side of the press.

One-hand guard actuation greatly increases production as theoperator uses his free hand to pick up the next part. By shorteningthe ram stroke to the minimum for the operation, cycle time andair consumption are reduced.

When the guard is pulled down the actuation lever rotates into thepilot valve, which in turn shifts the main valve. The cylinder strokesand the ram descends. As the toggle link straightens ram forceincreases reaching maximum tonnage at the bottom of the stroke.When the guard is released both valves shift back and the ramautomatically retracts.

Some operations such as pressing, forming andassembly require a slower downstroke. By adjusting the rate of exhausting air, the release of air and the downstroke is controlled.

With ample ram adjustment final depth setting is fastand accurate. Within the easily accessible air togglemechanism, ram adjustment and die set-up is simplified.

The ram stroke can be shortened to decrease cycletime, increase production and reduce air consumption.The convenient hand wheel reduces the cylinder volumeto reduce the stroke length up to 2-1/2".

Match the RMT Pressto the Job

The RMT press is extremely efficient and economical for almost everypunching and secondary operation. There’s no wasted motion! Byadjusting stroke length, depth, and speed, the RMT is matched exactlyto the work. Set-up from one job to the next is quick and easy.

Half Body Pressfor Custom Applications

The half body press combines the powerful RMT air toggle mechanism

with a unique frame design providing unlimited shut height for special

metalworking applications

Features include adjustable stroke length, ram adjustment and a keyed

tool mounting surface on the body

User must supply the valves and controls to operate the built-in 4 inch
