Junttan OY is a Finnish company specialising in the design, manufacture and marketing of hydraulic piling equipment. Founded in 1976 and located in Kuopio, Finland, Junttan developed the world's first concept of fully hydraulic piling machine in 1979. Since then Junttan has remained an industry leader in hydraulic piling machinery, whose product development is based on in depth co-operation with piling contractors around the world, ensuring industry needs are met.
Junttan's worldwide success is a result of both reliable products and effective after sales service. The latest HHK-A and HHK-S series hammers are designed to provide contractors with with highly efficient , environmentally friendly, exceptionally reliable hammers at relatively low cost.
Current industry trends are towards increasingly larger and more heavily loaded driven piles, hand-in-hand with even greater demands for efficiency. Greater performance must also be delivered with smaller environmental impact, governed by even tighter national and international regulations that have lead to the phasing out of diesel hammers.
Junttan HHK-A & HHK-S series hammers utilize a unique hydraulic differential on the downstoke to “assist” the ram block overcome losses that reduce efficiency in traditional “free-fall” hammers, resulting in 100% efficiency.
The Junttan HHK-A & HHK-S series of hydraulic hammers also utilise a large ram block mass with large end area to ensure highest possible “transfer ratio’ of potential energy into the pile being driven, resulting in greater efficiency.
