multi-way proportional direction valve: multi-way
proportional direction valve with manual control, DANFOSS from
Denmark
3 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 button 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 button 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.
