The SD30H is our company's newly developed four-linkage structure rotary drilling rig, designed to closely meet market demands and address issues such as difficult construction in complex strata and slow rock penetration efficiency. The four-linkage structure of this machine has been redesigned and re-laid out with an optimized structure, greatly improving construction stability. Meanwhile, while ensuring convenient transportation, it adopts a centrally positioned sunken main winch layout, effectively extending the service life of the wire rope. The reasonable layout of the main machine facilitates maintenance and servicing of the upper carriage.
