What is the working principle and basic composition of a truck-mounted drilling rig?
1 Answers
Truck-mounted drilling rig's working principle and basic composition are as follows: 1. Composition: A type of mobile drilling unit. All drilling equipment (drill rig, water pump or air compressor, derrick, and sometimes power unit) is assembled on various types of vehicles to form an integrated system. Based on mounting methods, it can be divided into self-propelled and trailer-mounted types. 2. Principle: For self-propelled truck-mounted rigs, all equipment is installed on a truck or tractor chassis. During operation, the vehicle's own power drives the drill rig and water pump (or air compressor). Trailer-mounted rigs have all drilling equipment including the power unit installed on various types of trailers (such as wheeled trailers or sled trailers). During operation, the power unit on the trailer provides energy, while transportation is achieved by towing with trucks or tractors. Both types allow the derrick to be laid down on the vehicle or trailer frame for integrated relocation, significantly reducing installation and dismantling time.
