6.1 Stationary platform is installed with four rollers matched up with front end of carriage to make trestle lift carriage for driving platform up or down.

6.2 Left-right movable platform is set in stationary platform and front-rear contracting platform in left-right movable platform; and all platforms are mounted with rollers. Driven by pressurized oil output by main pump, the platform is enabled to move right and left, and retract forward and backward by hydro cylinder.

Note: when the work is over, contracting platform should be in place.

  1. Hydraulic system (fig.1 Hydraulic system schematic)

The system uses open, single-pumped, paralleled fluid circulating mode, consisting of actuating unit, control apparatus, actuator, helper and service fluid.

  • Actuating unit

Active force comes from gear pump, namely engine driving PTO, and then PTO actuating oil pump for outputting service fluid.

Emergency pump is consisted of electric pump and hand-cranking hydraulic pump; and when electric pump does not work without electricity, hand-cranking pump could replace it.

  • Control apparatus

Control apparatus includes pressure valve, direction valve and flow valve.

Pressure valve: consisted of relief valve and throttle valve.

Relief valve adopts solenoid piloted relief valve. Non-moving solenoid valve makes relief circuit in  the system and motorized valve closed, so relief valve adjusts the highest pressure of system.

Adjustable throttle valve is mounted on the back of manifold block, adjusting hydraulic one-way valve to change pressure, clockwise turning for pressure build-up, and vice versa.

Direction valve includes two electro-hydraulic directional valves, two hydraulic one-way valves, two oneway valves, and four hydraulic reversible locks.

Solenoid directional valve controls contracting or extruding of lift supporting lugs.

Hydraulic one-way valve makes fluid move in one direction.

Reversible hydraulic lock is mounted besides every supporting lug for ensuring to be locked in contracting or extruding position.

Flow valve adopts a one-way throttle valve to adjust carriage descending speed, clockwise turning for speed build-up, and vice versa.

7.3 Actuator

 

Actuator includes carriage hoist cylinder, cylinder for supporting lug contracting or extruding and platform cylinder.

Platform cylinder uses two double-acting cylinders, and adopts hydraulic power station to control platform left-right moving and front-rear retractable.

Carriage lifting cylinder is of two one-stage plunger cylinders with lower supporting axle fixed on chassis, upper supporting axle on inner trestle, jacking structures adopting crossbeam trestle, and exhaust bolt mounted on the top of cylinder.

Supporting lug cylinder adopts four one single piston rods double-acting cylinders mounted on four supporting points of vehicle frame.

Electric system should include:

Part I for FVR34P series vehicles, lights and control circuits are designed according to operation manual.

Part II special electric circuit is designed according to handling characteristics and requirements of catering vehicles, mainly including circuits used in carriage up &down, supporting lug withdrawing & releasing, movable platform contracting or extruding, mobility control of left & right movable platform, and special lighting indication etc.

8.1. Control of Hydraulic system solenoid valve

  1. Mount PTO on engine, unlock driving cab; when main power switch K is on, carriage up & down, supporting lug withdrawing & releasing could be realized. Electrical circuit adopts “first dominating, priority control” interlock circuit, and only one action could be done one time, no two actions allow at the same time. Therefore, the second switch is on, it is still invalid. Besides, design adopts multi-cut relay, which improves reliability and safety greatly.
  2. Carriage uses parallel control(K2A-K2B;K3A-K3B), and operator can easily operate on ground or in cab.
  3. Contraction of movable platform and left & right moving is controlled by oil way of main pump. The button is set on control panel inside food carriage which could control relays, and output control voltage to the circuits inside carriage so as to control hydraulic solenoid valve.

For avoidance of collision between platforms and aircraft, two sensor switches are installed on both sides of buffering rubber hoses on front of platforms; when platform stretches out slowly, sensor switch feels the barrier (or aircraft), control relay circuit power is switched off, and then platform stops further moving.

 

8.2. Lighting and indication signal. Mainly carriage light, platform light, dimension light, indicator light for stopping driving, alarm lamp, engine trouble light, shift control light etc. are included; and the switches are mounted on driving instrument platform or operation panel, which are labeled on name board.
