SBSH-250/270-60KP FRAME PLATFORM DRILLING RIG

The frame platform it drills inclined holes with depth 55 meters. It is designed for working in hard mining and geological conditions at high abrasive rocks with hardness 6-20 units according to prof. Protodeaconov scale.

It has high speed lifting an lowering the drilling tool which is executed with electric hoists allowing to reach high speed at dismantling and building-up the drilling tool. The engine room is divided into two compartments: the compartment for electric equipment and the compartment for oil station and compressor which improves maintenance conditions and excludes possible negative consequences in emergency situations.

The mast, besides hydraulic clutch, is additionally fixed by braces with hydraulic clutches which provides stability of the mast while drilling in inclined position.

The feeding drive, instead of traditional hydraulic cylinders, is executed from two hoists with the drive from electric engines of alternating current with frequency regulation which provides stepless regulation of feeding speed while drilling and quick raising and lowering of the drilling tool.

The operator's cabin is equipped with control panels which make it easier to operate the drilling rig and provide all necessary information about the conditions of the parts of the drilling rig and parameters of drilling. The hydraulic drive of the drilling rig is based on the mobile hydraulics of "Bosch Rexroth". The control and distributing blocks provide the reverse connection with the pump which serves only that quantity of oil which is necessary for the executive pump to accomplish the operation with the established speed.

The level of block protection (JP67-69) provides their high reliability and work ability in any weather conditions.

The present drilling rig has united in itself all the main design decisions, checked by the multi-year exploitation at drilling rigs of our manufacture РД-10 and СБШ-250МНА-32, namely:

•     reliability, provided by the quality ofthe components and technology of manufacturing the drilling rig;

•     maintainability, which completely atisfies requirements ofthe customer;

•     efficiency of exploitation, especially at after warranty period;

•     life length before the major repair is over 40 000 hours;

•     ergonomics which unites easiness of control, awareness of the condition of different parts of the drilling rig and of parameters of drilling and comfortable conditions ofthe operator's work.
