HDY5 - hydraulic impact hammer with impact energy 60 kNm | Impact weight 5000 kg for driving reinforced concrete and steel tubular piles with a frequency of 30–80 beats/min
Description:
HDY5 is a hydraulic impact hammer with impact energy60 kNm, designed for driving reinforced concrete and steel tubular piles in cohesive soils, dense sands and soft rocks. Unlike vibratory hammers, which reduce soil resistance through vibration, the HDY5 delivers powerful discrete shock pulses to the pile, making it the optimal choice for rack piles operating on solid foundations, as well as for objects located near vibration-sensitive structures.
The basis of the HDY5 design isimpact weight 5000 kgfree falling from a controlled height. Thanks to the working stroke of the striking part up to1200 mm, the hammer provides maximum impact energy60 kNm in one cycle. Adjustable beat frequency range30–80 beats/min allows the operator to adapt the operating mode to different types of soil.
Low frequency (30-40 bpm) provides maximum energy transfer in dense layers, while higher frequency (60-80 bpm) improves performance in softer soils.
HDY5 hydraulic impact hammer works together with series hydraulic power stationE, it is recommended to use the modelE125. The hydraulic station supplies oil under pressure25 MPa into the hydraulic cylinder of the hammer, lifting the impact mass through a pilot-controlled cartridge valve. After opening the valve, the impact part is accelerated by gravity and transfers energy to the pile through a special damped impact transmission system.
This system includes an impact pad and a pile head damping ring. This solution protects both the impact mechanism and the top of the pile from cracks and damage, while ensuring the transfer of more95% of impact energy directly at the tip of the pile.
The advantage of impact technology compared to vibratory driving is the ability to effectively overcome high soil resistance at the end of the pile. This makes HDY5 particularly effective at reaching dense load-bearing layers at significant depths.
The status of a specialized solution for reinforced concrete and tubular piles is confirmed by the ability to work with various types of pile structures:
square reinforced concrete piles;
prestressed piles type PHC;
exposed steel tubular piles;
large-sized pile elements for industrial use.
The shock damping system includes a replaceable shock pad and polyurethane shock-absorbing ring that can be easily replaced on site without complex service equipment.
The total mass of the hammer together with the impact block and body is9450 kg, additionally provided with supporting equipment weighing200 kg.
Hydro stationE125 equipped with:
electric motor with a power of 90 kW;
maximum productivity 188 l/min;
hydraulic tank with a volume of 800 l.
The hammer is connected using lightweight aluminum power cables with a cross-section120–150 mm² and operating current200–250 A, which greatly simplifies transportation and installation compared to diesel impact hammers.
For contractors constructing bridge piers, foundations of high-rise buildings, industrial facilities and other structures that require driving reinforced concrete piles,HDY5 Ensures precise and repeatable impact energy transfer60 kNm.
Thanks to the shock mass5000 kg, working progress1200 mm, adjustable frequency30–80 beats/min and damped power transmission system, the HDY5 hydraulic hammer transforms a standard E-series hydraulic power pack into a highly efficient, low-noise and environmentally friendly piling machine. This makes it an ideal solution for urban construction and sites with increased environmental requirements.
