XCMG PRODUCT LIST
K type mast is made of H steel, and has the advantages of wide eyeshot and convenient transportation.
The substructure is Block package type which has good stability; while drawworks and mast adopt low-position installation and being lifted upon drawworks power.
Drawworks is a seal type chain transmission drawworks which has 4 forward gears+2 reverse gears (or 6 forward gears+2 reverse gears), and it equips auxiliary drive device for mast lifting and emergency lifting.
This rig is equipped with an integral driller's cabin, in which a driller can finish major operations and controls.
Between each part of rig transmission system adopt cardan shaft connection, which is convenient to install and disassemble.
Overall layout of the rig is reasonable, while its modularization can meet the requirements of integrally lifting, train and truck transportation.
