The test mast truck is modified on a HOWO ZZ5357TXFV464MF5 Type II truck chassis manufactured by China National Heavy Duty Truck Group Jinan Truck Co., Ltd. It adopts a 6×4 drive configuration. The main specialized equipment includes a winch, an engine power take-off (PTO) system, and other auxiliary facilities.
A rear-mounted truck-mounted crane is used in place of a conventional mast. Based on the actual operating conditions of testing operations, a rational power transmission system is designed to ensure that the chassis engine power can be simultaneously transmitted to the winch, hydraulic generator, truck-mounted crane, and circulation pump.
