Product Detail
HYZ750-2C Hydraulic coupling 
Type: Ahead Air cooled
Present point: 0
Point offset: 0.0

The HYZ750-2C hydraulic coupling ahead reducer we produced can match with the diesel engine of different models, such as

mestic 190 series, and CAT 3500, MTU 4000 series produced by America, which is suitable for mechanical drilling rig or

compound drive rig.

  The HYZ750-2C hydraulic coupling ahead reducer can be linked with the diesel engine through pins or linked with it directly.

It shares the same foundation with the diesel engine. Diesel-coupling device combination cooling system or individual wind cooling system can be adopted according to user’s

proposal and actual demands. With the application of CAD optimized gearbox structure and advanced modern CAM processing technology, it owns advanced economic technology index and compact structure; is convenient in repairing, maintaining and transporting, and can cope with all kinds of atrocious operational environment.

  The HYZ750-2C hydraulic coupling ahead reducer adopts hydraulic transmission oil as its working medium. The whole

transmissionsystem is soft and well balanced with the merits of good buffer action and damping effect ion. In addition, the hydraulic transmission provides over-load protection for the diesel engine, which will extend the diesel’s service life..
