Mali's landlocked position in West Africa relies heavily on cross-border highway logistics to move essential supplies from maritime ports to urban centers. Traversing long distances over variable road surfaces requires transport chassis built with high structural stability and heavy payload endurance.
To strengthen freight throughput, West African logistics client Joseph Manyanga acquired three customized 3 axle flatbed semi trailer units from ZW Group. Engineered to transport either intermodal containers or general break-bulk cargo, these 40ft semi trailers deliver dependable productivity across demanding regional transit routes.
ZW Group customizes vehicle parameters to match target payload limits and ground conditions. Key technical details for this delivery include:

The longitudinal main beams utilize high-tensile Q345B steel assembled through automated submerged arc welding. This fabrication technique provides complete weld penetration, eliminating structural weak points and protecting the chassis frame against sagging under max loads.
Featuring 12 retractable ISO twist locks, the 40ft flatbed deck easily transitions between container transport and general cargo. Fleet managers can haul a single 40ft container, two 20ft containers, or retract all locks flush to load bagged cement, timber, and heavy equipment onto the 3mm diamond plate floor.
Equipped with three 13-ton FUWA axles and heavy-duty multi-leaf spring suspension, the vehicle handles rough terrain with minimal stress. High axle load ratings keep chassis movement stable across unpaved roadways.
Protection against environmental wear starts with automated shot-blasting to clean the raw steel. Subsequent layers of zinc-rich anti-rust primer and polyurethane topcoats guard against ocean spray during transit and tropical weathering during service.

ZW Group controls every manufacturing phase, utilizing high-precision cutting and automated welding to deliver structural consistency and superior chassis durability across all models.
Our engineering team modifies beam dimensions, axle placement, and tie-down configurations to fit regional haulage guidelines and unique payload demands.
Using globally recognized components like FUWA axles and standard braking valves ensures maintenance components are easily accessible in West Africa, reducing equipment downtime.
Before dispatch, every completed chassis undergoes static weight tests, brake responsiveness verification, and alignment testing to guarantee instant operational readiness.
The trailer utilizes Q345B high-tensile steel main beams, 13-ton FUWA axles, and heavy leaf spring suspension to absorb severe impact on unpaved West African corridors.
It handles one 40ft container, two 20ft containers, or break-bulk freight such as bagged cement, steel coils, and timber via 12 retractable twist locks.
Q345B steel provides superior yield strength and resistance against frame twisting under maximum 50 to 60-ton payload conditions.
Each chassis undergoes shot-blasting, anti-rust zinc rich primer coating, and a polyurethane topcoat to withstand humid ocean transit and desert dust.
