pipe roller cradles The HPB16-30 has a 34 gal (128.7 L) fuel tank and a 100 gal (378.54 L)
hydraulic tank with 80 gal (303 L) fill capacity. The large hydraulic tank helps
keep the oil cooler, extending the life of the hydraulic system.
pipe roller cradles Hydro Control five-section hydraulic control valve provides bending and
winch operation. Hydraulic mandrel operation is a standard feature
on all Darby bending machines.
pipe roller cradles Machine side plates are reinforced with stiffeners for optimal frame
life. Side plates are 3/4" (19.1 mm) T1 steel and die nest plates are
1-1/2" T1 steel. All welds are preheated, heat controlled and made “in position.”
pipe roller cradles Parker Seal Lok™ hydraulic system prevents leaks and has a working pressure rating of 3,000 psi (206.8 bar).
pipe roller cradles Murphy control panel includes electric start, throttle control, oil pressure, tachometer and hour meter.
pipe roller cradles Hydraulic cylinders can be disassembled without cutting for ease of repair.
pipe roller cradles Frame cross tubes supporting the hydraulic cylinders have 3/8" (.375 mm) wall thickness.
pipe roller cradles Pinup is fully reinforced to prevent spreading.
pipe roller cradles 370 Quincy air compresor is hydraulically driven by its own circuit.
pipe roller cradles 10-micron hydraulic pressure and return line filtration keeps oil clean to extend the life of the system.
pipe roller cradles Oil cooler in compressor drive circuit keeps the circuit cooled. It continuously circulates, even when the compressor is not running. This extends the life of the hydraulic system.

pipe roller cradles Maximum bending force at front of stiffback is 381,700 lbs (173,139 kg).
pipe roller cradles Air compressor provides 240 psi (16.5 bar) for mandrel operation.
pipe roller cradles With engine running at 2,200 rpm, hydraulic vane pump produces 41 GPM (155 LPM) @ operating pressure.
pipe roller cradles 15 ton CAT style triple grouser tracks.
