FEATURES AND TECHNICAL SPECIFICATIONS

Features/Advantages:

	The HPB6-20 has a 17 gal (64 L) fuel tank and 35 gal (132.5 L) hydraulic tank with 29 GPM (110 LPM) fill capacity. The large hydraulic tank helps keep the oil cooler, extending the life of the hydraulic system.
	Parker four-section hydraulic control valve provides bending and winch operation. Hydraulic mandrel operation is a standard feature on all Darby bending machines.
	Machine side plates are reinforced with stiffeners for optimal frame life. Side plates are 5/8" (15.9 mm) T1 steel and die nest plates are 1" (25.4 mm) T1 steel. All welds are preheated, heat controlled and made “in position.”
	Frame cross tubes supporting the hydraulic cylinders have 3/8" (9.5 mm) wall thickness.
	Parker Seal Lok™ hydraulic system prevents leaks and has a working pressure rating of 3,000 psi (206.8 bar).
	Murphy control panel includes electric start, throttle control, oil pressure, tachometer and hour meter.
	Hydraulic cylinders can be disassembled without cutting for ease of repair.
	Pinup is fully reinforced to prevent spreading.
	325 Quincy air compressor is hydraulically driven by its own circuit.
	10-micron hydraulic return linekeeps oil clean to extend the life of the system.
	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.

Performance:

	Maximum bending force at front of stiffback is 207,000 lbs (93,893 kg).
	Air compressor provides 240 psi (16.5 bar) mandrel operation.
	With engine running at 2,350 rpm, hydraulic vane pump produces 29 GPM (110 LPM) @ operating pressure.

Options:

	Dual tires for added stability
	Tracks for reduced ground pressure
	Air-cooled Deutz Diesel Engine
