Product Description

Structure Overview

The refrigerated aircraft catering truck is a specialized vehicle designed for airport logistics. It primarily consists of the FVR Automobile chassis, supporting lug framework assembly, lifting trestle assembly, carriage assembly, platform assembly, refrigerating system, hydraulic system, and electric system.

Chassis Structure: Refer to the FVR34P truck operation manual for detailed chassis specifications.

Supporting Lug Framework: Adopts a vertical supporting style using hydraulic cylinders for contraction and extension. The framework is integrated with the vehicle frame. Note: Supporting lugs should be deployed when the vehicle is stationary/not in use.

Lifting Trestle: Constructed from four high-strength rectangular steel tubes, fixed to the vehicle frame and carriage using long and short pins.

Carriage Assembly:

Material: Uses specialized cooling vehicle plates with a totally-closed PU jointing structure and glass-fiber composite outer layers.
Insulation: Rigid PU foam thermal isolation material with an insulation coefficient ≤0.45 W/㎡·K.
Floor: Alloy skid-resistant aluminum plate for hygiene and easy cleaning.
Doors: Aluminum alloy rolling doors with fine sealing, torsional spring lifting, and manual locking.
Refrigeration: Equipped with Carrier 750S refrigeration units, independent diesel engine, and microcomputer control in the cab.

Access: Escalator and hand levers are mounted on the rear of the carriage for worker safety and access.

Platform Assembly: Includes stationary, movable (left-right), and retractable (front-rear) platforms with guard fences. Note: Ensure the contracting platform is in place after work is completed.

Hydraulic System Details

The system uses an open, single-pumped, paralleled fluid circulating mode, consisting of the following units:

Actuating Unit: Gear pump powered by engine PTO; includes emergency electric and hand-cranking pumps.
Control Apparatus: Includes pressure valves (solenoid piloted relief and throttle), direction valves (electro-hydraulic), and flow valves.
Actuators: Features carriage hoist cylinders (plunger type), supporting lug cylinders, and double-acting platform cylinders.
Auxiliary Devices: 2mm stainless steel fuel tank (160L), self-sealing oil filters, and high-pressure hydraulic tubes (32Mpa rating).

Electric System

The electric system is divided into standard vehicle circuits (FVR34P) and specialized catering truck circuits. Features include:

Interlock Safety: Only one hydraulic action can be performed at a time to prevent system conflicts.
Dual Control: Carriage lifting can be operated from both the ground and the cab.
Safety Sensors: Two sensor switches on the platform front prevent aircraft collision by automatically stopping movement upon detecting barriers.
Signals: Comprehensive lighting for the carriage, platform, and alarms.

Frequently Asked Questions (FAQ)

What are the main components of the refrigerated aircraft catering truck?

The truck consists of an FVR chassis, supporting lug framework, lifting trestle, insulated carriage, movable platform, and integrated hydraulic, electric, and refrigeration systems.

How is the carriage insulation achieved?

The carriage uses a totally-closed PU jointing structure with glass-fiber composite outer layers and rigid PU foam lining. This achieves an insulation coefficient of ≤0.45 W/㎡·K.

What safety measures prevent the platform from hitting an aircraft?

The platform is equipped with two sensor switches on the front buffering rubber hoses. When these sensors detect a barrier or the aircraft skin, the control relay automatically cuts power to stop platform movement.

What type of hydraulic oil and maintenance is required?

The system uses 46# hydraulic oil stored in a stainless steel tank. For maintenance, all service fluids should be changed completely during replacement to ensure system longevity.

How does the emergency hydraulic pump work?

In the event of an electrical failure, the system includes a hand-cranking hydraulic pump that can replace the electric pump to operate the critical components.

Can the carriage be controlled from multiple locations?

Yes, the design uses parallel control (K2A-K2B; K3A-K3B), allowing the operator to lift or lower the carriage from either the ground level or inside the truck cab.
