The flexible sliding curtain system allows convenient access to cargo from both sides of the trailer. Durable PVC curtain materials help protect transported goods from rain, dust, and external weather conditions.

The sliding rail mechanism enables smooth curtain movement during loading and unloading. Its practical design helps operators open and close the side curtains efficiently, reducing handling time during daily logistics operations.

The cargo restraint system provides secure attachment points for straps and other approved securing equipment. It helps limit cargo movement during transportation, supporting safer delivery of palletized goods and general freight.

The reinforced roof and support structure provides reliable support for the curtain system and upper trailer body. Its durable construction helps maintain structural stability during regular loading and transportation operations.

The three-axle configuration helps distribute cargo weight across the trailer, supporting stable handling and dependable road performance. Mechanical or air suspension options can be selected according to transportation requirements.

The rear door design provides convenient access for loading and unloading operations. Durable hinges and locking mechanisms help keep the doors securely closed during transportation while supporting efficient cargo handling.
