The new corrugated guardrail pile driver is a specialized driving and pressing equipment developed specifically for the construction corrugated guardrail steel pipe posts on high-speed roads, national and provincial highways, rural roads, ramps, and slopes. It features a fully hydraulic hammer drive and integrates three functions pile driving, pile extraction, and auger drilling. It is standardized to adapt to Φ114/Φ140/Φ130mm highway guardrail galvanized pipe posts and C-shaped steel posts. Requiring no concrete foundation, it is driven directly into the soil layer, making it the core construction equipment for new highway construction, expansion and old guardrail maintenance and emergency repairs. The four-wheel model offers fast transit speed and does not damage asphalt road surfaces, making it suitable for plain high-speed main; the crawler model has low ground pressure and strong climbing and off-road capabilities, adapting to mountainous areas, muddy slopes, and soft ground sections. Compared to traditional manual pile driving and excavatormounted hammers, construction efficiency is improved by more than 5 times, the verticality compliance rate of posts is nearly 100%, and labor and rework costs are significantly reduced.The diesel engine drives a high-pressure hydraulic main pump to provide power for the high-frequency hydraulic impact hammer; the hammer head reciprocates with strong impact along vertical guide rails to the pile head, relying on continuous impact potential energy to drive the guardrail steel pipe post into the design burial depth in one go; the post does not deviate or tilt throughout the driving process. For hard soil, gravel, and frozen ground, the auger drilling power head can be switched to pre-drill holes before driving the pile; for old guard removal and road renovation, the pile extraction clamp can be replaced to directly pull out the old steel pipe posts, covering the entire process with a single machine. Mainstream 7585/100 models of hammer heads feature adjustable impact energy of 600–1400J and an impact frequency of 240–20 times/minute, allowing for light frequency in soft soil and strong impact in hard soil to avoid compression deformation and mouth curling of the steel pipe posts; The pile cap is and customizable, adapting to national standard Φ114 and 140 guardrail round pipes and rectangular posts; The main hammer body is made of thickened wear-resistant steel, heat-treated for reinforcement to resist impact cracking, with easily replaceable wear parts, extending the service life by 60%; The dual shock-absorbing structure reduces the of the entire machine and extends the service life of the hydraulic system. Standard hammer stroke is 3.2–3.8m, meeting the 1.2–.5m burial depth construction requirements for national standard guardrail posts; The mast can slide left and right by 0–450mm and tilt forward and backward by0–20°, eliminating the need for frequent machine repositioning on narrow shoulders; The four-wheel tire model is equipped with 20.5-16 deep-t wire-reinforced wear-resistant tires, featuring four-wheel air-loss braking for stable and safe driving; Fully hydraulic steering allows a maximum transit speed of 30kmh, enabling direct driving on high-speed roads and reducing trailer transport costs; The entire machine weighs 4 tons with low ground pressure, leaving no scratches or damage on asphalt road surfaces Standard equipment includes a simple sunshade, with optional enclosed cabs, fans, or air conditioning. The centralized multi-way control valve, pressure gauge, and depth scale are into the control console, allowing beginners to become proficient in operation within half an hour; Overload pressure relief protection and an emergency stop button eliminate the risks of hammer stalling and bursting; The dual-pump merging energy-saving hydraulic system automatically reduces power when idling, with a comprehensive fuel consumption of 3.5–4.5L/h, 30% more fuel than older models; Hydraulic seals are high-temperature resistant and leak-proof, ensuring continuous and stable operation in high and low-temperature regions Standard driving function: Rapidly drives corrugated guardrail steel pipe posts into the ground; Optional auger drilling head: Pre-drills holes in hard soil, gravel, frozen soil to protect the pile body; Optional hydraulic pile extraction clamp: Used for old guardrail renovation and road widening to remove and recycle steel pipes; Reserved air compressor interface Can be fitted with a down-the-hole hammer to handle shallow rock layers.
