A guardrail pile driver is designed for installing steel posts used in highway guardrails and roadside safety barriers. It helps road construction contractors carry out post installation for highway projects, roadside protection systems, and road maintenance work.
YG offers two types of self-propelled guardrail pile drivers: four-wheel models and crawler models. Both are designed for guardrail installation, but their chassis configurations and technical specifications differ to meet different project requirements.
Whether you need a wheeled guardrail pile driver or a crawler-type machine with drilling capabilities, YG can help you evaluate a suitable configuration based on your post specifications, ground conditions, and installation requirements.

YG Guardrail Pile Driver Models
YG provides two main chassis options for guardrail post installation.
1. Four-Wheel Self-Propelled Guardrail Pile Driver
The four-wheel self-propelled guardrail pile driver combines a vehicle-style chassis with a hydraulic working system. Its four-wheel structure, rear-wheel drive, and dual hydraulic walking motors allow the machine to move independently between working positions.
Powered by a Yunnei 490 diesel engine rated at 37 kW, this model features a dual oil pump, dual-fan cooling system, and air braking system.
Key Features
- Four-wheel chassis: Supports independent movement between working positions.
- 37 kW diesel engine: Equipped with a Yunnei 490 engine.
- Hydraulic travel system: Uses rear-wheel drive and dual hydraulic walking motors.
- Dual oil pump: Supplies hydraulic power for machine operation.
- Dual-fan cooling: Helps manage operating temperatures.
- Air braking system: Provides braking support during machine movement.

Wheeled vs. Crawler Guardrail Pile Driver
YG offers two chassis configurations for different guardrail installation requirements. The main differences are their travel systems, working configurations, and technical specifications.
| Comparison | Four-Wheel Model | Crawler Model |
|---|---|---|
| Chassis | Four-wheel vehicle-style chassis | Tracked chassis |
| Travel System | Rear-wheel drive with dual hydraulic walking motors | Crawler travel system |
| Engine | Yunnei 490 | Yuchai 4-cylinder |
| Rated Power | 37 kW | To be confirmed |
| Operating Weight | Approx. 3.5 tons | 3.9 tons |
| Drilling Capability | To be confirmed | Up to 400 mm diameter and 6 m standard depth |
| Main Selection Factors | Road access and movement requirements | Ground conditions, drilling requirements, and site accessibility |
Which model should you choose?
Choose the four-wheel model when its vehicle-style chassis and travel configuration match your road construction site.
Consider the crawler model when you need a tracked chassis and its drilling configuration is suitable for your post installation method and ground conditions.
The final selection should also consider post dimensions, required installation depth, ground resistance, and compatible working equipment.
Applications of Guardrail Pile Drivers
YG guardrail pile drivers are intended for projects involving steel post installation for roadside safety barrier systems.
Typical applications include:
- Highway guardrail installation: Installing steel posts that support highway safety barriers.
- Roadside barrier construction: Supporting guardrail installation along national highways, provincial roads, and rural roads.
- Road maintenance: Assisting with new guardrail post installation and roadside barrier replacement.
- Transportation infrastructure: Supporting roadside protection projects during road construction and improvement.
The appropriate piling or drilling method depends on the post specifications, ground conditions, and machine configuration.
