Overall Vehicle Dimension

Hydraulic Vehicle Mounted Crane Data

Vehicle Composition

The welded frame has been made of steel plates and standard steel beams. It has been designed to receive:

• 2 Driver cabs, one on each side.
• 1 Power pack for the transmission’s and auxiliary tools power supply and the electric cabinet.
• Rail sections supports
• 1 Handling crane capacity 9 Tm 

It can be used for the transportation and handling of all kind of light equipment.

Axles

The vehicle has two types of axles:

• Front rigid axle
• Rear rocking axle with integrated rubber cushioning to limit rolling of the machine

The axles are mounted with 12.00 R24 rubber cushioned tyre. Each axle has its dynamic service brake and static parking brake in order to respect the current legislations.

Cabin

A driver cabin on each side of the machine guarantee easy driving in both directions. The driver will get in the right cabin and valid the cabin selection using the unique key.

Note: The reverse march remains possible but at reduced speed.

Both cabins are “one-seater”, free open access on both sides, steel structure including the roof with a polycarbonate windscreen, screen wiper and protection screen. Getting in & out can easily be done from each side at any time.

Inside you can find the following equipment:

• Cushioned driver seat
• Steering wheel
• Dashboard panel
• Engine control display
• Service brake pedal
• Accelerator pedal
• Dead-man’s pedal

On the dashboard, the following controls shall be provided:

• Emergency brake push button
• Buzzer
• Parking brake selector with integrated control lamp
• Cabin selector key and control lamp
• Driving sense FWD- REV selector
• Control lamps for ERROR and FIRE detection
• Rear axle joystick command
• Rear axle alignment control lamps

Dead Man System

This system has been installed in both cabins.

It obliges the operator to indicate his vigilance, using the dead-man’s pedal each 10 seconds.

If the operator doesn’t’ respect the 10 seconds delay, the buzzer will go on. If the operators still don’t react, within 10 more seconds, the vehicle will slow down and stop.

The same way, if the dead-man’s pedal remains activated continuously, the vehicle will also stop.

Electric circuit

The electric circuit can be divided into:

1. Main Power Circuit:

• Starter 24V / 4kW
• Pre-heater air inlet: 24V / 3kW
• Alternator capacity 24V / 55 Amp
• Starter batteries: 2x 12V / 105 Ah – 450 Amp.
• « FENWICK » connector capacity 160 Amp.
• Electric hydraulic power pack cap. 15 ltr/min @ 125 bars for parking brake release and/or crane operating in case of emergency.

Control Circuit :

• Combustion engine controller by BUS-CAN J1939 and EMR2
• Drive controller with Smart Drive EASY control box (one per cabin par cabin) through BUS-CAN-J1939 protocol connection;

Main control of the rest of the machine by central PLC (in electric cabinet) and one I/O slave interface cart in each cabin, communicating together through BUS-CAN Open protocol connection.

The VMS includes the following features:

Safety Features

Loader Crane Height Limiter

       To assist the work of operators in yards and along railway lines, cranes are fitted with special devices aimed above all at preventing accidental contact with overhead power lines (chain links).

Other Supplementary Devices

Management of crane slewing rotation with dual proximity sensor, to avoid use of the crane in areas where there are trains in transit, and key selector to determine the working side.

Cranes operating on rail vehicles have to be equipped with additional safety devices for rotation and height limitation not required by cranes mounted on truck in order to be in compliance with the “operational safety” standard in presence of double-track lines or electric traction line commonly referred to as “catenary.”

Country Of Manufacture

The VMS rail/road vehicle will be entirely manufactured and assembled in Singapore in accordance with dimensional drawings pre-approved by the Purchaser.
