Kales 5 Axle Tipper Trailer | 100 Ton U-Shape Mining Dumper

Key Specifications Overview

These are represented configuration values rather than a declaration of road legality. The signed technical agreement controls the final dimensions, payload envelope, component brands, material thicknesses and inspection scope.

African Mining and Route Fit

This 5-axle dumper is intended for high-volume, high-mass bulk cycles where a standard three- or four-axle trailer does not provide the required off-road payload envelope. Typical routes include pit-to-crusher, mine-to-plant, quarry-to-stockyard, private mine-to-port corridors and major earthmoving projects.

Best-fit cargo and operating conditions

• DRC and Zambia Copperbelt: copper-bearing ore, cobalt material, aggregate and mine-development spoil on controlled private routes.
• Guinea and West African bauxite operations: abrasive bauxite, wet laterite and high-rainfall mine-road cycles where body release and corrosion control matter.
• East African infrastructure corridors: clinker, limestone, coal, excavated material and aggregates, with axle-load calculations reviewed for the specific country and route.
• Southern African mines and quarries: iron ore, coal, crushed rock and heavy aggregate where tyre availability, brake support and workshop serviceability influence the component choice.

Check before selecting a 100-tonne configuration

• Confirm whether the route is a closed mine/private road or a public highway. The 100-tonne payload reference is not automatically legal under EAC, SADC, ECOWAS or national axle-load rules.
• Provide cargo density, maximum particle size, loading equipment and drop height so the body floor, sidewall and top-rail design can be selected for impact and abrasion.
• Confirm tractor model, axle arrangement, fifth-wheel height, PTO capacity, hydraulic flow, wheelbase and permissible kingpin load.
• Review turning radius, ramp gradient, cross-slope, dumping pad condition, overhead clearance and recovery access before approving an 11-meter body.

Why Choose the 5-Axle Configuration

• Higher represented mining payload: the 5-axle platform provides an engineering basis for a 100-tonne off-road payload, compared with up to 80 tonnes for the represented 4-axle model.
• Long U-shape body: curved floor-to-side transitions help reduce material retention when unloading clay, fines and mineral concentrates, while the longer body supports higher-volume cargo profiles.
• Dual front lift-axle option: the first two axles can be configured for pneumatic lifting during approved unladen operation, reducing tyre contact and rolling resistance. Actual fuel and tyre savings depend on route and control strategy.
• Rear mechanical tridem: the three rear axles use a field-serviceable mechanical suspension concept for heavy mine-road duty and straightforward workshop maintenance.
• Component choice for regional support: axle, brake, landing-gear and hydraulic brands can be aligned with parts availability in the destination market.

4-axle versus 5-axle mining tipper

Engineering, Hydraulic Safety and Quality Control

T700 chassis and NM500 dump-body architecture

The chassis uses a T700 high-strength steel concept with reinforced load paths around the kingpin plate, main beams, suspension hangers, hydraulic trunnion area and rear tipping pivots. The body uses an NM500 wear-steel concept in the abrasion zone. Material certificates, plate thickness and welding consumables should be listed in the confirmed production documents.

The U-shaped cross-section avoids the sharp internal floor corners found in a traditional rectangular body. That geometry can improve discharge of sticky or fine material and distribute local side impact differently, but it does not remove the need for correct loading practice or a level dumping surface.

Hyva FC A238-5 front-end hoist

The represented Hyva FC A238-5-07630-009-K0486 multi-stage cylinder is positioned at the front of the body to provide the stroke needed for an approximately 11-meter dump box. Before production, Kales checks cylinder stroke, closed length, tipping angle, mounting geometry, tractor PTO flow and hydraulic reservoir capacity as one system.

• The valve package can include limit and controlled-lowering functions according to the approved hydraulic schematic.
• An anti-rollover or body-angle protection function can support the operating procedure, but no valve makes tipping on soft, cross-sloped or unstable ground safe.
• Hyva, Binotto or another agreed package can be reviewed against local service coverage, seals, hoses and replacement-part availability.

Hybrid five-axle suspension logic

The represented layout combines two front air-suspension lift axles with a three-axle mechanical leaf-spring group at the rear. The lift axles are intended for approved empty-running conditions. They must be lowered when the load, speed, braking requirement or local rule demands full axle contact.

The rear tridem uses a heavy mechanical suspension concept that is familiar to many mining workshops. Final spring packs, equalizers, axle ratings, wheel-end seals and brake chamber sizes are selected around the intended duty cycle rather than treated as universal values.

Manufacturing and inspection plan

• Main-beam and body welding can use automated or robotic processes where the joint design and production batch make them appropriate. Welding procedure and welder qualification records can be included in the order inspection plan.
• Critical welds around the kingpin, suspension hangers, cylinder support and tipping pivots can be assigned ultrasonic or magnetic-particle inspection. The percentage, acceptance standard and reporting format must be agreed before production.
• Dimensional inspection, brake pressure/leak checks, hydraulic function tests and controlled tipping trials are completed according to the confirmed factory quality plan.
• Axle-load calculation, kingpin load, centre-of-gravity review and finite-element analysis can be supplied when the buyer provides complete tractor, cargo and route inputs.

Corrosion protection and ocean shipping

Export preparation can include abrasive blasting, an epoxy zinc-rich primer and a compatible topcoat or powder-coating system. The agreed surface preparation grade, dry-film thickness, colour and repair procedure should be recorded in the purchase specification.

• Hydraulic rods, landing-gear screws, kingpins, electrical connectors and exposed brake components receive shipment protection appropriate to the transport method.
• Marine wax, wrapping and desiccant can be specified for long ocean transit or high-salinity destinations.
• Stacking or semi-knocked-down shipment can be evaluated against trailer geometry, port handling capability and reassembly resources. Freight savings vary by vessel, route and quantity.
