Earth-moving trailers

TUHTI earth-moving trailers are designed for challenging applications.
High-quality materials, meticulous manufacturing techniques and modifications made on the basis of customer feedback ensure that our earth-moving trailers will last for years.

  • KCapacity 11,000 kg–18,000 kg
  • Tubular beam frame with high torsional strength
  • High-quality FAD hubs
  • Backboard with hydraulic control (WS 150 D3 drop gate)
  • High backboard opening height (WS 150 D3 no limitations)
  • Front wall higher than the sides
  • 6 mm bottom plate made of abrasion-resistant steel
  • 4 mm side walls made of abrasion-resistant steel
  • WS 180 D3 with a drawbar with springs
  • 2-wheel brakes a standard option
  • Grain walls as an accessory

FRAME AND TRAILER BED

  • All earth-moving trailers have a multi-axle chassis
  • The frame and trailer beds are dip-painted allowing paint to penetrate the frame bars
  • The trailers have a tubular beam frame with high torsional strength, the frame beams are also made of tubular beam
  • The long drawbar (approx. 1.5 m) makes the trailer easy to manoeuvre even with twin tyres
  • The WS180D3 trailer has a drawbar with springs (mechanical leaf spring)

WALLS PANELS AND BOTTOM

  • The front wall is 150 mm higher than the side walls
  • Bottom plate made of 6 mm abrasion-resistant steel, 8 mm abrasion-resistant steel in N110D3 and N130D3 models
  • In the WS120D2 and WS180D3 trailers, the inner corners are angled by 150 mm
  • The N110D3, N130D3 and WS150D3 trailers have sharp inner corners
  • The long sides of the bed are equipped with box girders to support the bottom corners
  • The side walls have no vertical support structures, which allows them to yield under pressure, preventing permanent deformation.
  • The top edge has a solid bar that ensures the edge retains its shape
  • The bottom has the minimum of traverse support structures, allowing it to yield under pressure, preventing permanent deformation.

MULTI-AXLE CHASSIS

  • PHigh-quality wheel hubs manufactured by FAD/li>
  • Symmetrical bogie with lowered pivot points.
  • The bogie’s middle axle is lower than the hub axles and the trailer climbs over obstacles easily whether moving forward or backward.
  • In all our dumpster trailers, the rocker mechanism is equipped with round roller bearings

BACKBOARD

  • Backboard made of 4 mm abrasion-resistant steel
  • The WS120D2 and WS180D3 trailers are equipped with a backboard that opens upwards with a hydraulic cylinder, also when the grain cassette is mounted
  • In the WS120D2 and WS180D3 models, the backboard automatically locks behind fixtures in the corner column when closed, preventing the weight of the load from opening it
  • To ensure safety, in the WS120D2 trailer the backboard is equipped with a hose break valve and with a double-lock valve in the WS180D3 trailer
  • The N110D3, N130D3 and WS150D3 trailers are equipped with a drop-down gate that is operated with a hydraulic system
  • The drop-down gate’s operating cylinder is equipped with a double-lock valve to ensure that the gate remains secure
  • In the model with a drop-down gate, the weight of the load opens the gravel backboard when the drop-down gate is opened, and closing the drop-down gate also causes the gravel panel to close
  • Trailers with a drop-down gate do not have any overhead structures that would hinder unloading (unless a separate gravel panel is used), and the drop-down gate can be turned down to extend the bed length by 40 cm, enabling longer items to be transported.
  • The backboard has no bars inside that would make loading or unloading more difficult
  • Backboard stopper chains as a standard feature (gravel panel stopper chains in models with a drop-down gate)

BACKBOARD OPENING MECHANISM

  • In the WS120D2 and WS180D3 models, the grain cassette’s backboard opens with a hydraulic cylinder when the trailer’s own backboard is opened
  • In the N110D3, N130D3 and WS150D3 models with a drop-down gate, the grain cassette’s backboard is opened by the weight of the load and closed when the drop-down gate is closed
  • The grain cassette can be mounted and detached ready-assembled

GRAIN CASSETTE

  • Grain cassette thickness 3 mm, wall height 750 mm
  • In the WS120D2 and WS180D3 trailers, the grain cassette is fixed with 8 M12 hex head screws (side and front walls) and 2 fastening pins (backboard)
  • In the N110D3 and N130D3 trailers, the grain cassette is fixed with 8 M12 hex head screws (side and front walls) and 2 pivots (top of the side walls)
  • In the WS150D3 trailer, the cassette is secured with clamps on the side
