80 t · 160 t · 200 t — hydraulic pile pressing inside existing factory buildings, renovation projects and tight urban sites. No noise, no vibration, no spoil.
The CFZYJ series is a compact hydraulic static pile press built for jobs conventional rigs cannot enter: inside existing workshops, between plant equipment, next to occupied buildings. It clamps the pile and pushes it into the ground with pure hydraulic force — silent, vibration-free and with zero spoil.

All three models share the same low-headroom philosophy: short clamp stroke, built-in pile crane and a walking chassis that repositions itself inside the building.
The most compact unit — drives Ø350–400 mm piles with only 900 mm side clearance. Ideal for reinforcement inside operating factories.
The workhorse of the range — 14 m pile sections, Ø500 mm round piles and a 12 t pile crane, yet still presses 1 m from a wall.
The heavy-duty unit — 2000 kN jacking force and a 16 t crane for large-diameter, deep-foundation work in confined industrial sites.
The CFZYJ press clamps the pile between fixed and moving jaws, then uses long-stroke hydraulic cylinders to press it statically into the ground. Because the load is transferred without impact, surrounding soil is densified rather than disturbed — with minimal noise, vibration and settlement.
A self-walking chassis crawls along the jacking line inside the building, and the built-in crane picks and pitches each pile section, so no external crane is needed in the confined space.

Foundation strengthening inside operating plants — production lines stay in service while piles are pressed between equipment.
New buildings squeezed between existing structures where a conventional piling rig cannot physically fit.
Bridge abutments and approach spans where vibration from impact driving would damage existing structures.
Shaft and cut-and-cover works in built-up districts with strict noise and settlement limits.
Extensions adjacent to occupied, vibration-sensitive buildings — work continues during teaching and treatment hours.
Heavy machine and warehouse-rack foundations added inside existing logistics and industrial buildings.
