Description

The Chieftain SB18 Dump Trailer is designed to handle intensive transport applications where strength, flexibility, and reliability are essential. Offering an 18 tonne carrying capacity, the SB18 provides operators with the ability to efficiently transport both machinery and materials while maintaining exceptional towing performance and operator comfort across challenging working conditions.

Built on heavy-duty commercial fast-tow running gear, the SB18 features robust 10 stud commercial axles, powerful 420 x 180 braking systems with automatic slack adjusters, and a combined air and hydraulic braking system with load-sensing technology for enhanced safety and braking control under load. Its parabolic spring suspension with adjustable torque arms, combined with a four-spring sprung drawbar system, delivers smoother towing, improved load distribution, and increased stability during high-speed road transport and demanding site work.

The trailer's heavy-duty square body construction incorporates a 10mm steel floor and 6mm steel sides, making it ideal for transporting aggregates, soil, silage, machinery, demolition waste, and general site materials. Galvanised ramp storage trays positioned beneath the body provide practical storage for loading ramps, allowing operators to safely transport excavators, dumpers, telehandlers, and other plant equipment when required.

Designed with durability, usability, and long-term performance in mind, the SB18 comes equipped with flotation tyres, full LED lighting with flashing strobes, an invisible drop-down hydraulic tail door, stainless steel toolbox, galvanised components, aluminium crash barriers, adjustable hitch, and multiple integrated safety features as standard.

Optional upgrades including Hardox 450 floor and side packages, aluminium clip-on ramps, tyre upgrades, reversing camera systems, and front-to-rear sheeting systems allow the SB18 to be customised for specialist applications and intensive daily operation.

Positioned as a larger-capacity model within the SB range, the Chieftain SB18 Dump Trailer delivers the ideal combination of versatility, durability, and commercial-spec performance for professional operators working across agriculture, plant transport, construction, and contracting industries.
