Product Details And Working Principle of Diesel-powered & Hydraulic System Highway Guardrail Pile Driver

Equipment Purposes

The guardrail pile driver can be used for pile driving, pile extraction and drilling, and is applicable to various scenarios where pile driving, drilling and pile extraction are needed, such as highway guardrails, expressways, photovoltaic power plants, farms, ranches and orchards.

Three systems

I mainly use three systems to understand this pile driving equipment, namely the power system, the control system and the working system. Now, please allow me to explain them one by one. 

I. Power System

The power system consists of a diesel engine, an gear pump and a hydraulic system, just like the heart and blood in a human body. The diesel engine adopts the National Standard II Changchai 490-B four-cylinder engine with a power of 38Kw and can provide a maximum of 52 horsepower. The gear pump is driven by the diesel engine to pressurize the hydraulic oil. Finally, taking the hydraulic oil as the medium, it provides power for the whole pile driver to carry out operations. This is how the hydraulic system works.And this product of wheel-mounted guardrail pile driver adopts the right-handed 540 gear pump.

II. Control System 

The control system uses the multi-way valve and also takes the hydraulic oil as the medium. It controls the valves of the hydraulic oil to achieve the control of the working system. The brake, throttle and air cut-off brake lever can also be regarded as part of the control system. Operations are carried out through proper manipulation.

III. Working System

The working system includes that the plum blossom frame controls the forward and backward tilting, the slide rail controls the left and right movement, the large arm and the small arm control the up and down movement of the hydraulic hammer, the pushing frame and the hammer splint fix the hydraulic hammer on the vertical guide rail to work up and down. 

Product Highlights:

1.The 4.2m high vertical guide rail can handle the columns with a height below 3.2m. Meanwhile, it is applicable to three models of round piles (114mm and 140mm) and square piles (130mm). It can meet the needs of all application scenarios in China. For various pile types abroad, they can be handled just by customizing the hammer head.

2.The Guolier Changchai 490-B four-cylinder diesel engine is powerful and diesel is cost-effective. Meanwhile, engines of various brands and with different emission standards can be customized according to customers' needs.

3.The wheelbase is 1.78m. In China, most of them are still 1.65m. The lengthened wheelbase of 1.78 meters makes the pile driver more stable when working, driving, pile driving and drilling.

4.A three-way valve is set up to accelerate the oil return speed and improve the working efficiency of the guardrail pile driver.

5.The brake is upgraded. The front wheels adopt disc brakes and the rear wheels adopt air cut-off brakes. Among them, the air cut-off brake is equipped with an air dryer and an air storage tank.

6.The easily worn parts of the pile driver are all quenched to make them more durable. The easily damaged parts are thickened and strengthened, so their service life is longer.

7.Durable Chaoyang tires are selected.

8. The explosion-proof resin fuel tank eliminates the risks of the fuel tank and is safer.

Finally, the working principle of the guardrail pile driver I've expounded applies to the vast majority of guardrail pile drivers/drilling machines that use diesel engines and hydraulic systems. If there are any inappropriate expressions, you can discuss with me at any time.Thanks for your reading.
