YC-21 Hydraulic Impact Pile Driving Hammer

Operating Principle

The operating cycle consists of a few parts ram, cylinder, powerpack. It begins with the lifting part of hydraulic cylinder through the energy transmitted from the hydraulic power system. When the hammer ram lifted by the hydraulic cylinder reaches the preset stroke position, the part of piston automatically allows the ram to freely fall under the acceleration of gravity.

And then the hammer ram produces the hitting energy to complete the pile driving process. After impact, the cycle is repeated automatically.

Detailed Introduction

Product Features

ROBUST AND RELIABLE

Solid and simple frame design is the basis for a long working lifetime. Vibration and noise reduction levels are achieved through a special and innovative frame design. Optimal frame weight and balance guarantee high efficiency of the hammer.

STRONG BUT GENTLE

Accurate strokes and balanced hammer block acceleration prevent pile head damage and guarantee a long working lifetime of the hammer.

EASY CONTROL

The ingenious hydraulic and electrical system design allows the impact energy, blow rate and frequency to be easily adjusted according to soil conditions and pile type. YONGAN hammers can also be crane suspended. Different accessories make crane suspension an easy process.

YONGAN HAMMERS ARE GREEN

Hammers are equipped with shut-off valves which prevent oil leakages. Biodegradable oils can be used. All exhaust gas is filtered when YONGAN power packs are used.

NOISE REDUCTION

As a result of sustainable development for a safer and more efficient solution to reduce noise demands, YONGAN has improved structural solutions and accessories, including special drive caps, insulation skirts to significantly reduce noise pollution.

VERSATILITY AND SITES

YONGAN hammers can drive concrete piles, steel piles, straight piles, batter piles, and marine pilings. They are also fit for onshore, offshore, underwater and Wind Power base, bridge construction projects and adapted for all kinds of conditions
