Import multi-way proportional direction valve:
multi-way proportional direction valve with manual control,
DANFOSS from Denmark

Electrical control
3.1 Adopt
*2V control power
3.2
Electrical part includes main electrical control box and
portable type hand-operated box.
3.2.1
Hand-operated box handle is front and back push-draw mode. It
is light and easy to carry and operate. Its function is to
control cylinder to realize every operation and control engine
accelerator. It also can realize to cut over of cylinder speed,
over-load warning shown and control. When over-load occurs,
automatic stop and keep current state.
3.2.2
Main electrical control box has double way pneumatic control
valve in order to control rotating speed of engine.

Function
4.1 This
system adopts double oil pump and converging valve to realize
fast and slow speed control and two units multi-way
proportional direction valve control.
4.1.1
This system can realize landing gear and main beam single
action or work together through selecting and manual
switching to realize converging or non-converging.
4.1.2
This system can realize main beam cutting over between high
speed under non-load or low speed under heavy load through
selecting and manual switching to realize non-load and
heavy load.
4.1.3
Lift of this system can divide into two gear, *0T and *0T,
realize safely lift according to landing rear position, and
control Max. lift capacity as per landing gear sensor feedback
signal to avoid tip under over-load.
4.2
Hydraulic lock and single and double balance valve are fixed
directly on cylinder in order to work safely.
4.3 Left
side of the whole system control 5pc cylinders, ride side of
the whole system control another 5pc cylinders, total *0pc
cylinders.
4.4
Considering badly working environment and high operation
frequency, main hydraulic units adopt import multi-way
proportional direction valve and hydraulic oil pump, other
hydraulic auxiliary parts adopt domestic good quality hydraulic
units.
4.5 This
system has pressure sensor and equipment running buzzer warning
marker.
4.6
According to different position of landing gear, the system has
two different lifting capacity to avoid overload and
fault.

Configuration
Axle:
Baohua axle (Standard), BPW and FUWA for option.
