ZW Trailer 4-axle 40CBM hydraulic side dump trailer delivers heavy-duty capacity, robust construction and precise side-tipping hydraulics for efficient bulk material transport. Made in Shandong, China; delivery 20–30 days.
Detailed Description
Designed for heavy-haul fleets and contractors who demand reliable cycle times and minimal downtime, this 40CBM hydraulic side dump trailer combines large volume capability with robust engineering. The trailer’s 35–40 CBM body is configured as a full drawbar assembly to deliver excellent longitudinal rigidity and lateral stability while operating on busy sites or public roads. With a solid hydraulic tipping system and purpose-built frame sections, the trailer supports efficient side discharge of bulk materials with controlled, predictable motion and high operator confidence.

Structural Integrity and Materials
Structural decisions—such as the 500mm beam height, 18# channel side beams, and heavy-gauge wing plates—are selected to resist deformation under repeated heavy loads. The upper wing plate (16mm), lower wing plate (18mm) and web (10mm) combine to provide a stiff, durable body shell. ZW Trailer offers multiple steel grades (Q235, Q345, T700) so purchasers can balance cost and tensile requirements according to application demands.
Safety and Braking
Safety systems are specified to commercial standards: WABCO braking components provide dependable stopping power and modulation under load. A robust king pin (90#), JOST landing gear and a 24V LED electrical system improve connection reliability and nighttime visibility. The full drawbar layout contributes to tracking stability and predictable handling when cornering or reversing.
Operational Efficiency
The 40CBM capacity enables the transport of larger volumes per trip, reducing the number of runs required for bulk materials such as sand, gravel, demolition waste, or specialty aggregates. Typical users include civil contractors, quarry operators, municipal works departments and large logistics firms. When operated as a Side Dump Full trailer or as part of a mixed fleet, the trailer reduces fuel consumption per tonne moved and improves on-site throughput.
Why Choose This Model?*
Proven structural design: engineered beam heights and plate thicknesses for heavy duty cycles.
- Efficient unloading: advanced hydraulic FC202 system for controlled side dumping.
- Operational savings: larger payloads per trip reduce labor and fuel costs.
Reliable components: WABCO brakes, JOST gear and industrial-grade king pin for safe operation.
ZW Group manufactures the trailer in Shandong with a typical lead time of 20–30 days and a monthly capacity of 300 sets. This combination of regional production scale and component quality delivers a competitively priced, dependable solution for demanding haulage tasks. Whether specified as a Side Dump Full trailer or integrated into a fleet of 4 axle full dump trailers, the product supports higher utilization rates and lower per-tonne transport costs.
