Volvo BL71 heavy duty backhoe loader: mining systems: arm for closed structures, fewer parts, less weld, and higher strength. Big arm base is made of cast steel, has a very high strength, while still capable of the agile movement and rotation. While in the transport operation, large arm hydraulic lock, and Rotary are locked by a PIN lock, security. Optional attachment bracket allows quick changing other device driver, you can also install an alternate hydraulic circuit for accessories, hand tools and other excavator loader attachments. BL71 mining depth to 4.30M, bucket digging force for 59KN. Narrow long s -shaped arm provides a wide field of visio, dual joystick and standard two-joystick manipulation in two ways from which to choose. Small elongation arm pedal control, added more uses for the device. Active part is inside a small arm, can improve the lift capacity, to reduce weight. Rigid hydraulic pipe installed in the upper arm, can be very well protected, excavator hydraulic circuit with flow regeneration feature that eliminates cavitation and accelerating the pace of operations. Priority valve ensures that the working device of the relative velocity is not constant, shortening the cycle time for the job. Optional leg locking mechanism ensures security. Legs equipped with rubber pad on the bottom.
Loading system: patented loading servo control system greatly simplifies the loading operations. A joystick control system, which can precisely control the loader driver with the minimum force all actions: lift, unload, scoop reset as well as jitter, etc. Before/after the joystick is there a shift button, you can simplify fuck speed cycle time for the job. Mount arm is a box-shaped welded structures, including a tubular cross member, can improve strength without increasing weight of cases, providing greater lift capacity. Operation is simple:VOLVDD4D -turbo engine is a 4 cylinder,4 l water-cooled diesel engine. Its power is over 70kn.
