Product Introduction 01

Hanfa Group rolls out the HF20+ rotary piling rig, a space-efficient foundation equipment engineered to handle piling tasks across residential building sites, public infrastructure, PV farms, urban municipal jobs and high-speed rail schemes. Fitted with crawler travel assemblies and sophisticated pressure-assisted drilling systems, this unit reaches a maximum bore depth of 20 meters and forms piles with diameters spanning 400mm to 1200mm, suiting diverse ground foundation work scenarios.

Its framework adopts thickened high-tensile steel paired with refined welding craftsmanship, granting great structural sturdiness and extended service cycles. All vital mechanical parts are shaped via precise CNC fabrication to maintain consistent precision even during nonstop heavy-duty work. Equipped with the brand’s exclusive drive transmission setup, this small-sized rig outputs robust drilling force, striking a perfect balance between compact footprint and powerful excavation capacity.

Product Introduction 02
