Implementation example
JUNTTAN HHKA series hydraulic pile hammers. Ram mass: 3 – 14 tonnes пример внедрения

HHK4A hydraulic pile hammer attached to Junttan PM23 pile driving rig. Project: warehouse construction (London, the UK). Pile type: 15-meter concrete pile. The project contractor: ‘We were satisfied with our working efficiency and performance when using the HHK4A. The hammer contributed to the actual production of up to 40 piles a day’.

JUNTTAN HHK A series hammers (Finland) are applied to drive different piles: precast concrete piles, steel piles, sheet piles, and wooden piles.

Pile driving is energy, time and cost efficient as up to 95 per cent of JUNTTAN hydraulic hammer energy is transferred to installed pile.

Efficiency.

JUNTTAN hammers contribute to up to 20 per cent higher productivity than traditional hammers with similar mass.

Applicability.

HHK A series hammers are applied to drive different piles: precast concrete piles, steel piles, sheet piles, and wooden piles.

Performance.

The hammer and pile cap design ensures low noise and vibration during operation.

User friendliness.

The hammers can be easily connected to different hydraulic systems. They are able to be operated from inside the cab and using remote control.
