Description
Field contractors struggle to punch structural steel on remote sites without dragging bulky machines. The Edwards 25 Ton Dual Station and Portable Power Unit provides 50,000 pounds of punch force with an uncoupling mobile hydraulic cart. Operating on 460-Volt 3-Phase plant power, it suits heavy industrial yards. Its 25-ton punch limit cannot pierce plate over 1/2-inch.
The punch head uses heavy C-frame cast ductile iron that resists frame yawning under maximum hydraulic tonnage. A remote 3-HP portable power unit connects through 20-foot high-pressure hydraulic hoses with dripless quick-disconnect couplers, transferring hydraulic fluid at 3000 PSI. Portability strains lightweight frames. This modular setup uses an oil-filled steel cart frame with solid rubber wheels that protect the hydraulic pump, motor, and fluid reservoir from rough gravel yard transit.
Dual Station Portable Hardware Matrix
Plant maintenance crews punch structural steel flanges and shear angle iron in tight spaces. Detachable power units operate auxiliary tooling up to twenty feet away.
- 25-Ton hydraulic punch station punches 1-1/16-inch holes through 5/16-inch mild steel plate.
- Portable roll-around power unit rolls across jobsite gravel to power remote hydraulic tools.
- 460-Volt 3-Phase motor draws minimal amperage while maintaining constant 3000 PSI pump pressure.
- Dual work stations accept interchangeable shear, notcher, and bending press tooling attachments.
- Heavy 20-foot hydraulic hose lines provide wide work reach without moving the main power pack.
- Dripless quick-connect couplers prevent hydraulic fluid spills during tool changeovers.
- Electric remote foot pedal control allows single-operator positioning and punch cycling.
Hydraulic Power Pack Telemetry Data
Hydraulic flow testing on 460-Volt 3-Phase power records an idle electrical draw of 1.8 Amps, rising to 4.6 Amps at full 3000 PSI punch relief pressure. Pump flow rate measures 3.2 GPM under continuous load. Reservoir oil temperature stabilizes at 134°F after two hours of steady cycle punching. Pressure drop across the 20-foot hose line measures under 45 PSI at maximum flow. Acoustic noise measures 72 dBA at 5 feet from the mobile hydraulic power unit.
Industrial Field Service Work Boundaries
Never disconnect pressurized hydraulic hoses while the electric motor runs because high-pressure fluid injection risks cause catastrophic tissue trauma. Do not purchase this 25-ton unit for heavy structural bridge fabrication where 1-inch plate punching is required. Kinking hydraulic hoses causes internal wire braid fracture and line bursts.
- Inspect high-pressure hydraulic hoses per week for outer jacket cuts, bulges, or fluid leaks.
- Wipe quick-disconnect couplers clean before locking hoses into the portable power pack.
- Change hydraulic fluid and replace the return line filter cartridge every 500 operating hours.
