pipe roller cradles The HPB22-36 has a 35 gal (144 L) fuel tank and a 120 gal (454 L)
hydraulic tank with 100 gal (379 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 1" (25.4 mm) T1 steel and die nest plates are
1-1/2" (38.1 mm) T1 steel. All welds are preheated, heat controlled
and made “in position.”
pipe roller cradles Frame cross tubes supporting the hydraulic cylinders have 3/8" (9.5 mm) wall thickness.
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 Pinup is fully reinforced to prevent spreading.
pipe roller cradles 390 Quincy Air compressor 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 763,000 lbs (346,090 kg).
pipe roller cradles Air compressor provides 240 psi (16.5 bar) continuous pressure for mandrel operation.
pipe roller cradles With engine running at 2,200 rpm, hydraulic vane pump produces 74 GPM (280 LPM) @ operating pressure.
