1. Integral rotation type adopts hydraulic and machinery driving, realizes the stepless speed for the workover device and substructure model of carrier; Caterpillar motor matched with Allision transmission is reasonable ,safe ,high efficiency, steady and increases the power ratio of motor. 2. Drilling and workover equipments are equipped on the carrier increases the movability of equipment, shortens the installation readiness time of rigs and raises the efficiency of drilling. 3. Integral hydraulic air driving operation system and double crown block saver have worker’s intensity labor relieved and raise the operation safety. 4. Adopting integral forging brake drum ,force internal recycle cooling, raise the braking safety and service life and is favor of protecting the environment 5. Air and flameout protection device and galloping protection device satisfy the special requirements in oil and gas well.
