Three-axle flatbed, 12500*2500*1550mm, 34000kg payload at only 6000kg tare.

Overview

What This Trailer Is Built For

A three-axle flatbed at 12500*2500*1550mm with a 6000kg tare and a 34000kg payload inside a 40000kg gross, all figures plus or minus 5 percent. A 6 tonne tare on a 12.5 metre flatbed is light, and it comes from the kingpost construction: 14mm upper, 16mm lower and 8mm middle plate at 480mm high, with 90mm x 13mm x 10-piece plate springs. Axles are three FUWA 13T sets on reinforced mechanical suspension, landing gear is FUWA 28T, the kingpin is JOST 50# or 90#, braking uses 30/30 chambers on the rear two axles with a WABCO brake valve, and lighting is 24V LED.

Key Benefits

What You Get

  • 6000kg tare on a 12.5 metre flatbed converts directly into 34000kg of payload
  • Graduated kingpost plate at 14mm upper, 16mm lower and 8mm middle puts steel where the stress is
  • 30/30 brake chambers on the rear two axles with a WABCO valve
  • Open flat deck takes containers, machinery, steel and oversize loads
  • 24V LED lighting outlasts filament lamps on rough roads
Problems Solved

What It Fixes

  • Heavy flatbeds waste several tonnes of the gross rating on the trailer itself

Comparison

How It Compares

Compared WithHow This Model Differs
Sidewall cargo trailerThe open deck takes oversize and crane-loaded cargo; side walls contain loose and bagged goods.
Lowbed trailerThe flatbed is lighter and better for containers and steel; a lowbed is needed for tall machines under height limits.
Heavier flatbed buildsA 6000kg tare gives 34000kg payload where a heavier flatbed of the same length gives several tonnes less.
Use Guide

Operating This Trailer

  1. Lash cargo at proper anchor points, since there are no sides to contain it
  2. Spread concentrated loads over the deck rather than onto a single crossmember
  3. Check the 30/30 chambers on the rear axles at every brake service
  4. Verify twist lock engagement before moving a container
  5. Inspect the kingpost plate and mountings at each service
