Technical Support and Training
Operating a semi trailer is not the same as operating a truck and the difference shows up in damage.
How This Works in Practice
After purchasing SINOHENG trailers, customers need not worry about technical issues. We provide comprehensive technical support, and every vehicle is supplied with a detailed operation manual presenting each step in an illustrated format, covering engagement and disengagement, use of the braking system and turning technique.
Step by Step
Illustrated operation manual
Supplied with the vehicle so drivers can study coupling, braking and turning before they are under load.
Coupling and uncoupling
The most common source of early damage, covered step by step for the kingpin and landing gear fitted to your trailer.
Braking system familiarisation
Dual line pneumatic systems behave differently from rigid truck brakes, particularly loaded and on descents.
Maintenance schedules
Detailed maintenance recommendations for wear parts, including inspection intervals and replacement cycles.
Ongoing support
A 24-hour after-sales hotline records the problem and puts a technician in contact to agree a repair plan and timing.

Is the manual in English?
Yes, and it is illustrated rather than text only, which matters when the driver and the manual do not share a first language.
What if a driver damages the kingpin?
Most of our trailers use bolt-in kingpins precisely so they can be replaced in the field rather than cut out.
How do I reach support?
WhatsApp or email reaches us fastest. The 24-hour hotline is for breakdowns; routine questions are better in writing so we can send drawings back.
