ZJ30/1700CZ Truck-mounted drilling rig max drilling depth 3000 meter with API standard
Truck Mounted Drilling Rig
Adopting double engine compound power system, the truck mounted drilling rig is a truck-type rig developed independently by LSPE, which is able to operate with either of the two engines or twin-engine incorporation. The gear parallel auxiliary box is reliable in transmission and easy to be maintained. The auxiliary braking system of drawworks adopts air control water cooling plate and reinforced chassis. The load distribution is reasonable, and the real axle is air suspension trailing axles.
Technical Features
The power transmission system uses Caterpillar engine and ALLISON hydraulic mechanical transmission case with reliable performance and low failure rate.
Centralized control of electric, air and hydraulic system, main components adopts international brand.
The main drawworks drum is with an integral type of lebus rope groove, main brake uses band brake or hydraulic disc brake, the auxiliary brake is as air control water cooling plate brake, air clamping brake or electromagnetic eddy current brake, etc. The bailing drum can be provided.
The API is two-section flexible mast type, realizing lifting and expansion by utilizing oil cylinder.
The drilling floor is a folding type floor, lifting by hoist with stable structure and convenient installation.
The power is taken off by auxiliary box from vehicle-bone engine for the operation of chassis adopting overloading wide axle with good cross-country and travel performance, low section tire, high strength girder, steering mechanism assisted by hydraulic power, dual braking system, which is suitable for complex conditions of oil field with long service life.
By modular and humanized design, the rig includes new driving cab, embedded step ladder, automatic lock pin of API, crown block and centralized lubricating system of drawworks as well as electric, air and hydraulic centralized control of engine hood designed according to different climate and district, the main components are imported.
The top drive system can be chosen.
