Application Scenarios

Where It Is Used

Honest Comparison

How It Compares With the Alternatives

2-axle container trailer	The 3-axle unit handles heavier loads and distributes weight better on poor roads, but has higher purchase and maintenance cost
Air suspension trailer	Leaf spring is more reliable in dusty or high-temperature regions and requires less maintenance, but offers less ride comfort
Low-bed trailer	This skeleton trailer has a higher deck for container clearance, but is less suitable for heavy or oversized cargo that needs lower loading height

Use Guide

Using It Well

Check tyre pressure and twist lock condition before each trip
Lubricate twist lock mechanisms monthly in dusty or humid environments
Verify brake system function before long hauls, especially after long storage
Use supporting legs when uncoupled to prevent frame sagging on soft ground
