ALLSTEEL Straight Side Press Offers:
The heart of the ALLSTEEL hydro-mechanical straight side press is the mechanical linkage system. Using only one hydraulic cylinder, the linkage allows all the benefits of hydraulic drives, such as variable stroke, variable speed, variable tonnage, and overload protection, while avoiding the need for expensive failure-prone hydraulic balancing systems required by conventional multi-cylinder hydraulic machines.
The ALLSTEEL system uses Fiberglide® lubrication-free bushings and hardened pivot pins for a long, maintenance free life. The connecting rod, loaded in tension, assures parallel movement of the ram regardless of off-center loading. Two-point linkage support combined with eight-way gibing assures precise ram movement and repeatability. Machines with ram bolsters wider than 48" are equipped with four point suspension to assure parallel operation with loads offset front to rear as well as left to right.
Other substantial benefits of the ALLSTEEL system include low headroom design and shock-free operation due to the inherent damping action of hydraulics. The machines are safer, because there is no high energy flywheel. The machines require low maintenance, as there are no gears, clutches, brakes, pitman, or sensitive servo systems and other high-maintenance items.
Finally, they are a great value. ALLSTEEL has over 50 years of experience in the construction of hydro-mechanical presses. This track record, combined with superior resale value and low initial investment, is unsurpassed in the industry.

The Allsteel Advantage
Two-cylinder hydraulic machines; partial tonnage available with offset load. |
ALLSTEEL hydro-mechanical machines; full tonnage available with offset load... Fast approach and return speed, variable stroke length. |
Hydraulic balancing systems can fail, causing expensive die damage!
Why take this risk with your valuable tooling? Simple dirt contamination of a valve could cost thousands of dollars. Furthermore full tonnage is available only at the center of the ram, or with balanced load distribution. |
With the ALLSTEEL system, it is impossible for the ram to get out of level, regardless of off-center loading.
Infinitely variable pressing speed and pressing stroke length.
Unlike hydraulic machines the ALLSTEEL system is designed to deliver full rated tonnage at either end of the ram, this means much more flexibility in job setup |
Optional Features
-
PLC based controller for high speed machines and to facilitate integration with pressing lines.
-
Full CNC controls for rapid setup and multi-axis applications.
-
Extra high ram speeds for high production work and for long stroke jobs.
-
Larger open heights to accommodate oversized tooling.
-
Extra long strokes to allow deeper draws and more tool clearance.
-
Tonnage control and limiter to protect valuable tooling from accidental overload.
-
Knock out system in ram to ease part ejection problems.
-
Hydro-pneumatic cushions to allow the use of draw-type tooling.
