  Chassis: The chassis uses an Actros3332 (Europe Ⅲ) 6x4 type  chassis. The engine utilizes an OM 501LA V6 turbocharged & Inter-cooled intelligently controlled diesel engine with strong power output of 315HP. Its ample cab is comfortable and equipped with double-layer sleeper and air suspension adjustable seats. The gearbox is a synchronous automatic gear shifting type, and chassis load capacity is so high that its allowable total mass can reach 33 tons under full load. With ABS and ASR intelligent control, the brake system is safe and reliable. This type of truck is the optimum choice for deep logging work in domestic oil fields.
 Drawworks: 26000ft drawworks or double type 23000ft drawworks can be installed(with hydraulic elevation, the small drawworks is convenient for operation). Its drum is cast with full-anti-magnetic steel, and dynamic balance tests have been done after machining and heat treatment. Its drive is stable and reliable. Its brake system is a double--belt pneumatic control brake and a tension overload automatic brake device is installed to ensure safety. Its framework is welded using high-grade seamless rectangular tubes and firmly connected to the subsidiary beam to ensure advanced performance, safety and reliability.
 Drawworks Transmission System: the main hydraulic system and hydraulic generator drive are independently controlled. The main system uses engine full-power take-off with output torque that can reach 1217lb.ft. With great power, it is convenient for operation. The hydraulic system utilizes a closed-circulation loop drive and volume variation stepless speed regulation. The hydraulic chain drive system selects the domestic pneumatically controlled large torque gearbox, which is suitable for deep well operations. The drawworks will shut down automatically in case of system overload in order to ensure safe running of the equipment. The full hydraulic transmission system uses a W16T hydraulic shifting gearbox that is originally assembled in the USA with a large speed regulation range and neutral shift. The two transmission ways are applicable for all kinds of working conditions in logging. Its minimum speed can be lower than 98.4ft/h so as to meet super low-speed working requirements. The hydraulic generator is driven by the power output on the gearbox side.
 Carriage: The carriage is using a steel framework and the deck inside the operation cabin is made of straight grain stainless steel plate. After polyurethane foaming treatment, the carriage body has excellent heat conservation performance and is installed with a COLEMAN ceiling-mounted air-conditioner imported from the USA. The operation table and toolbox are made using a 5700 structure to create a comfortable environment. The drawworks cabin floors are 0.15in waved aluminum plate, underneath which are strong and durable steel sheets. The outside deck is processed with aluminum oxidation sand-blasting treatment; the surface is coated with imported Dupont paint so that perfect performance can be permanently maintained in severe environments.
 Rope Guider Device: The upper rope guide is hydraulically controlled. With hydraulic power and an imported control valve, it is convenient for operation. This system also has a servo-buffering function so that it is convenient and reliable for operation.
 Electrical System: This system is equipped with a HARRISON hydraulic generator, imported diesel generator and external power which can be used synchronously or independently to meet the requirements of different electrical devices. The lighting installed on the wellhead can be self-rotated so as to ensure a safe driving environment and convenient logging operation.
 Auxiliary System: Instrument racks have been equipped with rollers with an airbag structure for convenient use.
