1. the featuresof

the drilling rig adopts the automatic Telescopic style with two high strength oil cylinder support, a set of hydraulic valve control rigs operating supine, which is time-saving, safe and reliable to maximize the benefits for users.

the chassis adopts rubber track, light weight and low life cycle cost, which can reduce noise of vehicle running mechanism, reduce car body vibration, and reduce fuel consumption greatly. It can walk on urban roads without hurting the road surface.

the chassis is equipped with four high strength threaded legs (or hydraulic high leg). the installation and adjustment is fast and convenient. It can be used for leveling of work plane, loading and unloading vehicle, which reduces the hoisting cost and improves efficiency and works as auxiliary support.
