Product Description

1 Structure Overview

Refrigerated aircraft catering truck is mainly consisted of: FVR Automobile chassis, supporting lug framework assembly, lifting trestle assembly, carriage assembly, platform assembly, refrigerating system, hydraulic system, and electric system etc.

Chassis & Framework Refer to FVR34P truck operation manual for chassis structure. Supporting lug framework assembly adopts vertical supporting style, using hydraulic cylinder for supporting and contracting job, while supporting lug framework is combined with vehicle frame into one.

Note: supporting lug should be on when vehicle is not used.

Lifting Trestle Lifting trestle is composed of four high-strength rectangle steel tubes, and fixed into vehicle frame and carriage with long and short pins.

2 Carriage Assembly

Consisted of front and rear door frame, header, floor, left/right side plate and front/rear rolling door etc.

Material: Totally-closed PU jointing structure with out-inner layer of glass-fiber composite plate. Insulation coefficient (W/㎡, K) ≤ 0.45.
Floor: Alloy skid-resistant aluminum plate, featuring clean and easy maintenance.
Rolling Door: Aluminum alloy with fine sealing and torsional spring lifting mechanism.
Interior: Stainless steel guard plates and international standard fixed belts for dining vehicles.
Refrigeration: Carrier 750S units with independent tri-vortex diesel engine and AC 380V auxiliary motor.

3 Platform & Escalator Assembly

Platform Components Consisted of stationary platform, left-right movable platform, front-rear retractable platform and guard fence. Driven by pressurized oil, 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.

4 Hydraulic System

The system uses open, single-pumped, paralleled fluid circulating mode.

Control Apparatus: Includes pressure valves (relief and throttle), direction valves (electro-hydraulic), and flow valves. Reversible hydraulic locks are mounted on every supporting lug for safety.

Actions		1DT	2DT	3DT	4DT	5DT
Carriage	Up	+	-	+	-	-
Carriage	Down	+	+	-	-	-
Supporting Lug	Releasing	+	-	-	-	+
Supporting Lug	Withdrawing	+	-	-	+	-

Note: 1DT-electromagnetic relief valve; 2DT-5DT-directional valve; "+" indicates power on.

5 Electric System

Interlock Circuit: Adopts "first dominating, priority control" to ensure only one action at a time.
Parallel Control: Carriage operation easily managed from ground or cab.
Safety Sensors: Two sensor switches on platform front to avoid aircraft collision.
Indication: Includes alarm lamps, engine trouble lights, and shift control lights on the operation panel.

Frequently Asked Questions

Q1: What materials are used for the catering truck's carriage insulation?

The carriage uses totally-closed PU jointing structure with glass-fiber composite plates and rigid PU foam lining, achieving an insulation coefficient ≤0.45 W/㎡.K.

Q2: How does the platform prevent collisions with aircraft?

The platform is equipped with two sensor switches on both sides of the front buffering rubber hoses. When an obstacle or aircraft is detected, the relay circuit cuts power to stop movement.

Q3: Can multiple hydraulic actions be performed simultaneously?

No, the electrical circuit uses an interlock design where only one action can be performed at a time for safety and reliability.

Q4: What happens if the electric pump fails?

The system includes an emergency hand-cranking hydraulic pump that can replace the electric pump if there is no electricity.

Q5: What type of service fluid is required for the hydraulic system?

The system uses 46# hydraulic oil. It is recommended to change all service fluids completely during replacement.

Q6: Are the carriage doors manual or automatic?

The rolling doors are equipped with torsional springs. They lift automatically once unlocked but must be pulled down manually to lock.
