Configuration Comparison

5 Axle vs 6 Axle Lowbed Semi Trailer

A six-axle lowbed adds an additional axle position compared with a five-axle configuration. This may provide additional possibilities for distributing supported mass across the trailer axle group.

However, the additional axle also affects trailer tare weight, overall geometry, turning radius, tire scrub, suspension complexity and legal axle-group limits. The final selection must reflect the cargo and intended transport route.

Heavy Transport Engineering

Understanding Six-Axle Lowbed Load Distribution

A semi-trailer transfers supported weight through the kingpin and fifth-wheel connection and the trailer axle group. The resulting reactions depend on the cargo's weight and center of gravity, the trailer's own mass distribution, and the positions of the support points.

Kingpin Reaction Six-Axle Group Cargo Position

Conceptual diagram only. Not a certified engineering drawing or approved loading plan.

Supported Trailer Mass = Kingpin Reaction + Total Axle-Group Reaction Simplified static equilibrium relationship for the supported semi-trailer system.

Moving the cargo forward generally increases the kingpin reaction. Moving it rearward may increase the axle-group reaction. The actual distribution must be calculated for the combined trailer and cargo system.

For ultra-heavy transport, the engineering assessment must also include local platform loading, suspension load sharing, longitudinal bending, torsional effects and dynamic forces.

Capacity Assessment

Can a Six-Axle Lowbed Carry 70, 80, 90 or 100 Tonnes?

The suitability of a six-axle lowbed for a particular cargo weight cannot be determined from the number of axles alone. The trailer must be assessed as part of a complete transport combination.

Permissible Payload = Permissible Supported Trailer Mass − Trailer Tare Weight The permissible supported mass must be established from all applicable structural, component, tractor and legal constraints.

70-Tonne Cargo

Requires calculation of axle-group reactions, kingpin load, structural limits, tractor capacity and applicable road limits.

80-Tonne Cargo

Requires detailed engineering review. A combined nominal axle rating of 72–78 tonnes does not itself authorize an 80-tonne payload.

90-Tonne Cargo

May require a specialized heavy-haul configuration, different axle arrangements or alternative transport equipment.

100-Tonne Cargo

Requires project-specific structural, vehicle-combination and route assessment. Modular or other special transport solutions may need consideration.

These cargo weights are illustrative engineering assessment scenarios. They are not declared payload capacities of the trailer displayed on this page.
Maneuverability

Six-Axle Steering Systems and Turning Performance

With six axle positions, steering geometry becomes particularly important for tight industrial sites, port terminals, mining areas and infrastructure projects.

Fixed Axles

A mechanically straightforward arrangement. Turning behavior and tire scrub must be considered in relation to axle spacing and operating conditions.

Self-Tracking Axles

Selected rear axles may follow the turning path under appropriate conditions. Reversing and axle-locking arrangements require attention.

Hydraulic Steering Axles

Multiple hydraulically steered axles can be evaluated for restricted turning areas and specialized heavy-haul operations.

Why Steering Matters on a Six-Axle Lowbed

A longer axle group can increase lateral tire forces during tight turns. An appropriately engineered steering arrangement may help manage maneuverability and tire scrub, but adds components, controls and maintenance considerations.

The final steering system must be evaluated for forward and reverse operation, locking requirements, suspension geometry, axle loads and applicable approval rules.
Suspension Engineering

Mechanical vs Air Suspension for Six-Axle Lowbeds

Consideration Mechanical Suspension Air Suspension
Operating Principle Mechanical spring and equalization arrangement Air springs with leveling and control equipment
Ride Characteristics Dependent on spring and load design Can offer different ride and leveling characteristics
Maintenance Mechanical wear points and inspection Air lines, valves, air springs and controls
Load Sharing Depends on equalization geometry Depends on pneumatic system and axle arrangement
Selection Project and road dependent Project and road dependent
Structural Design

Reinforced Chassis for Ultra-Heavy and Concentrated Loads

Heavy equipment does not necessarily distribute its weight uniformly across the loading deck. Crawler tracks, machine wheels and industrial support points can create concentrated loading.

Longitudinal Bending

Main beams must be assessed for bending moments generated by cargo weight and support geometry.

Torsional Rigidity

Uneven road conditions and asymmetric cargo loading can introduce significant torsional forces.

Local Deck Reinforcement

Crawler contact areas and concentrated equipment support points may require additional structural reinforcement.

Gooseneck Structure

The gooseneck and kingpin assembly must be designed for the calculated fifth-wheel reaction and operating loads.

Loading Equipment

Hydraulic Ramps, Loading Angles and Machinery Clearance

The loading system must be selected according to the machinery's operating weight, track width, ground clearance, contact pressure and approach angle.

Ramp Angle = arctan (Vertical Rise ÷ Horizontal Run) Simplified ramp geometry. Approach and breakover clearance must be checked separately.

Hydraulic Dual-Cylinder Ramps

  • Powered ramp operation
  • Custom ramp length options
  • Steel grid or other suitable surfaces
  • Project-specific hydraulic and locking systems

Spring-Assisted Ramps

  • Mechanically assisted operation
  • Alternative ramp handling arrangement
  • Requires appropriate locking and balance
  • Must be designed for the loading case
