60-TONNE · 3-AXLE · HYDRAULIC PLATFORM · 13.4 M EFFECTIVE LOADING LENGTH

NEW PRODUCTION · DIRECT FROM THE MANUFACTURER · CE DOCUMENTATION

(PLEASE FIND OUR CATALOGUE ATTACHED IN YOUR LANGUAGE)

Built for serious heavy-haul operations, the CASTROMAX® CST-MXHP 3 LOWBED combines a 60,000 kg payload capacity, three 12-tonne axles, a hydraulic gooseneck loading platform and a practical 13,400 mm effective loading area.

The hydraulic platform over the gooseneck creates additional usable loading length, allowing the effective loading area to increase from 9,000 mm to 13,400 mm.

This makes the CST-MXHP 3 particularly suitable for transporting combinations such as a paver and roller, heavy construction machinery, industrial equipment and other demanding loads where additional usable deck length is required without moving to a telescopic trailer configuration.

HYDRAULIC GOOSENECK PLATFORM

The key feature of the CST-MXHP 3 is its hydraulic gooseneck loading platform.

The hydraulic platform can be raised to approximately 14°, creating a continuous loading area over the gooseneck.

This increases the effective loading length from 9,000 mm to 13,400 mm.

The additional usable loading area allows operators to carry longer machinery combinations or multiple machines while keeping the overall trailer architecture compact and practical.

For applications such as paver and roller transport, the hydraulic platform provides a major operational advantage by allowing the gooseneck area to become part of the usable loading surface.

AXLE CONFIGURATION AND MANOEUVRABILITY

The CST-MXHP 3 uses three 12-tonne axles with air suspension.

One axle is self-steering, improving manoeuvrability during cornering and helping reduce tyre scrub.

One axle is equipped with hydraulic lift functionality.

The combination of self-steering and lift-axle technology helps improve handling, tyre life and operating efficiency depending on load conditions.

This configuration provides a practical balance between payload capacity, stability and everyday manoeuvrability.

MECHANICAL PLATFORM WIDTH EXTENSION

The standard loading platform is 2,550 mm wide.

Mechanical side extensions provide an additional 250 mm on each side.

With both extensions deployed, the total usable loading width increases to approximately 3,050 mm.

The additional width makes the trailer suitable for transporting wider tracked machinery, construction equipment and other loads exceeding standard road-width dimensions.

REAR HYDRAULIC LOADING RAMPS

The CST-MXHP 3 is equipped with hydraulic bi-fold rear loading ramps.

The ramps provide an approximately 10° loading angle for easier and safer machinery loading.

The ramp system also includes 200 mm hydraulic lateral adjustment, allowing the ramp position to be adapted according to the track width of the machinery being loaded.

This provides additional flexibility when transporting construction machinery with different undercarriage widths.

CHASSIS AND MATERIALS

The chassis is manufactured using certified high-strength structural steels:

• SSAB S700MC PLUS
• S690QL
• S355J2+N

The chassis architecture is engineered around optimised weight distribution, structural durability and heavy-haul operating conditions.

The use of high-strength structural steel provides the strength required for intensive machinery transport while maintaining an efficient chassis design.

PAINT PROTECTION

The chassis and structural surfaces undergo a complete industrial surface-treatment process.

All surfaces are prepared with:

• Sandblasting
• Anti-corrosion epoxy primer
• Two-component acrylic paint

Customer-specific colour configurations can be supplied according to order requirements.

BRAKING AND SAFETY SYSTEMS

The CST-MXHP 3 is equipped with a WABCO 4S3M EBS braking system with ABS and RSS roll stability support.

The braking system is designed for professional heavy-haul operation and provides electronically controlled braking across the axle group.

The trailer is also equipped with TPMS tyre-pressure monitoring as part of the standard equipment package.

HYDRAULIC ADVANTAGE

The CST-MXHP 3 is designed for operators who need more usable loading length without moving to a telescopic lowbed.

The hydraulic gooseneck platform converts the front section of the trailer into usable deck space.

This provides:

• 9,000 mm standard loading platform
• Up to 13,400 mm effective loading area
• Additional flexibility for carrying multiple machines
• Compact overall trailer architecture
• Easier loading through the hydraulic platform geometry

The result is a practical heavy-haul configuration for machinery transport where deck utilisation is critical.
