Abstract: A crawler-mounted remote-controlled tractor to control and recover spillage of pipeline is presented. This machinery is composed of 2 major systems: actuating system and remote-controlled operating platform system, which is applicable for control and recovery of leakage oil under various terrains in case of pipeline leaking accident. The machine is self-developed on the design principle of guaranteeing personal safety and environmental protection, and on the technical thinking "to change blocking into guiding". With this kind of machine, the safety of the workers involved in pipeline rush-repair can be guaranteed effectively, in addition to increase recovery rate and decrease extent and degree of leaking oil contamination. The machine has a high security, reliability and practicability.
