Why Choose the Kales Telescopic RGN Lowbed?

In the heavy transport industry, versatility is profit. The Kales 2-Line 4-Axle Telescopic Lowbed Trailer eliminates the need for multiple specialized trailers. Designed specifically for the rugged road conditions of Africa, Latin America, and Central Asia, this trailer combines a hydraulic detachable gooseneck (RGN) for safety with a telescopic main beam for flexibility.

One Trailer, Two Missions:

• Heavy Mode (Closed): Keep the beam retracted to transport concentrated heavy loads like excavators, transformers, and crushers (up to 80 Tons).
• Long Mode (Extended): Extend the telescopic beam by 4,500mm to transport indivisible long cargo such as wind turbine blades, bridge beams, and long pipes.

Key Features & Manufacturing Excellence

1. Robust Structure: Built with High-Strength Steel

We understand that durability is paramount. This trailer is manufactured using high-strength steel (HG60), offering exceptional durability and service life.

• Maximized Load Bearing: The robust frame and low-profile design ensure it can withstand the heaviest loads (80 tons concentrated), while maintaining strict safety standards.
• Reinforced Stress Points: Structural reinforcements at critical areas—such as the gooseneck connection and suspension mounts—enhance its load-bearing capacity, preventing structural failure under extreme stress.

2. Wide Bed Design: Superior Stability

Safety on uneven terrain is non-negotiable. The trailer is equipped with a wide bed (3,000mm), providing a vast support area for transporting large equipment.

• Even Load Distribution: This feature not only distributes the load evenly, reducing localized pressure on the trailer frame and tires, but also significantly improves stability during transport.
• Rollover Prevention: The wider track and deck protect valuable cargo from damage caused by instability, especially when cornering or navigating rough mining roads.

3. 2-Line 4-Axle Configuration

Unlike standard 3-axle trailers, our 2-line 4-axle design utilizes short axles with a total of 16 tires.

• Low Ground Pressure: This design significantly increases the tire contact area, reducing ground pressure. It is the ideal configuration for soft soil, muddy construction sites, and off-road mining environments.

4. Precision Telescopic Technology

The sliding mechanism is the heart of this trailer. We use precision-machined guide rails and reinforced locking pins.

• Rigidity Guaranteed: Even when fully extended to 4.5m with a 50-ton load, the main beam maintains excellent rigidity without sagging or deformation.

5. Kales Electrostatic Powder Coating

We don’t just paint; we protect. Our trailers undergo a full shot-blasting process followed by electrostatic powder coating and high-temperature baking. This finish is 5x more resistant to corrosion, salt spray, and stone chips than traditional wet paint—perfect for sea freight and coastal operations.

Real-World Applications

This trailer is engineered to serve multiple industries:

• Mining Operations: Ideal for transporting heavy jaw crushers, screeners, and mining dump trucks. The low ground clearance ensures a low center of gravity on uneven terrain.
• Wind Energy Projects: Extend the frame to safely transport wind tower sections or turbine blades.
• Infrastructure Construction: Move long precast concrete beams, steel structures, and piling machinery without renting a second specialized trailer.

Quality Assurance & Testing

120% Overload Test Guarantee: Before delivery, every Kales telescopic trailer undergoes a rigorous static pressure test at 120% of its rated capacity. We simulate extreme loading conditions to ensure the main beam shows zero permanent deformation.

Reliable Hydraulic System: We use top-tier hydraulic cylinders with multi-layer sealing technology. Tested under high pressure for 48 hours to ensure zero leakage. The system operates smoothly even in extreme African heat or Central Asian cold.

Frequently Asked Questions (FAQ)

Q: How does the hydraulic detachable gooseneck work?

A: The trailer includes an independent diesel engine power station. You simply start the engine and use the control levers to lower the deck to the ground and detach the neck. The truck drives away, leaving the deck flat for safe front loading. The process takes less than 15 minutes.

Q: How do you ship this oversized trailer?

A: Due to the 3m width and length, we typically ship via Bulk Cargo Ship or Ro-Ro Ship. We apply a thick wax layer to the entire trailer and cover the engine/hydraulics with waterproof cloth to prevent saltwater corrosion during transit.

Q: Can I customize the extension length?

A: Yes! While the standard extension is 4.5m, we can customize the telescopic length up to 8 meters depending on your cargo requirements and local road regulations.
