    Dongyu Hydraulic Press

1. Environmental protection and energy saving, compared with traditional diesel hammers, no oil fume pollutes the atmosphere

2. Strong penetrating power, more penetrating power to sand and cobblestone layer than traditional diesel hammer,

3. Simple operation, easier to operate than traditional diesel hammer construction

4. Low noise, 70db smaller than traditional diesel hammer construction

Dongyu hydraulic hammer currently has 11 models, ranging from y-3 to dh-40, with impact energy from 24Km to 600knm. Our company can customize different types of equipment according to customer needs to meet the needs of various working conditions.

The hydraulic hammer can be applied to different types of piles and meet the requirements of various working conditions, such as: cement round piles, cement square piles, cement sheet piles, steel sheet piles H-type piles, steel pipe piles, etc.

This equipment can be used for fixed pile frame or crane hoisting method, and can be adjusted according to the host owned by the customer to make it suitable. Our equipment can also be used to pull out piles or modify them slightly for rapid foundation consolidation.

The hydraulic hammer can use the pile driver's own power system or be equipped with Dongyu special power station, and we have a series of supporting power stations for customers to choose.

All circuits and hydraulic systems can be easily operated by a control panel or a portable controller. The whole machine adopts a closed oil circuit. By adjusting the speed and oil pressure, the equipment is reliable and environmentally friendly, as well as efficient and safe.

Dongyu Pile Hammer---Provide customers with the best piling plan!

    Working principle

First, it is powered by the hydraulic power system, which is delivered to the pile hammer through a high-pressure hydraulic hose, and the hammer core is lifted. When the hydraulic cylinder lifts the hammer core to a certain height, the hydraulic reversing valve makes the upper and lower parts of the hydraulic cylinder piston at the same pressure. At this time, the piston falls freely under the action of gravity, and the hammer core produces a striking effect to complete the piling process.

02Accumulator

It functions high and low pressure. It reduces the shock pressure, and control the ramto drop in a speed 130 % of free acceleration .

03Piston rod

04Ram strocke range

Operator can see ram drop height easily and can adjust ram stroke height during pile driving through remote control box .

05Ram

It is comprised of one or more ram segments and stands complicated physical and chemical tests before application.

06Drive Cap

All the cushions are inserted in it. They could protect the hammer structure,components and piles, reducing the noisy

    Features

“Dongyu” hydraulic hammer is suitable for bridge piling, offshore wind power piles, and building pile foundation construction. The hydraulic hammer can be used for fixed pile frames, and can also be used for crane lifting and can be adjusted according to the host owned by the customer to make it suitable . All the circuits and hydraulic systems of the Dongyu impact hammer can be easily operated by the control panel or remote control. The whole machine adopts a closed oil circuit. By adjusting the speed and oil pressure, the equipment is reliable and environmentally friendly, as well as efficient and safe. The key parts of the "Dongyu" hydraulic hammer are made of internationally renowned brands, and the shell is sprayed with nano anti-corrosion materials. From small screws of grade 12.9 to imported engines, "Dongyu" treats every product like a handicraft. Impact hammer Using humanized design, it can automatically piling and accurately control the stroke, and it also has the function of "anti-driving". Different from other manufacturers. The core of the "Dongyu" hydraulic impact hammer is forged, which not only guarantees Long-term piling operations can also penetrate the soil layer to the elevation strongly and forcefully drive the piles to the strong weathered layer. "Dongyu" power station can also use imported frequency conversion motors, stable performance, no noise and no pollution during work , Green and environmental protection. Compared with traditional diesel hammers, hydraulic hammers are environmentally friendly, pollution-free, and low noise are more popular with start-up masters. In construction operations, hydraulic hammers not only drive faster, but also have higher efficiency at the same impact energy.
