HKL300R Crawler Solar Pile Driver
The HKL300R is a purpose-built crawler pile driver designed to excel in demanding outdoor environments. Its core function is pile driving, with drilling available as an optional configuration , making it adaptable for a wide range of projects including non-road highway fencing, solar farm construction, and various agricultural applications like fencing in farms, pastures, and orchards .
Power and Performance
At its heart is a high-performance diesel engine with 85kW of power at 2600 r/min, providing a powerful and reliable power source for demanding construction work . This engine is tuned for superior performance and enhanced fuel economy, ensuring long operational hours with lower running costs.
Advanced Hydraulics for Precision Work
The machine features an advanced hydraulic system with a working pressure of 22 Mpa and a total gear pump displacement of 40+40+25 ml/r . It utilizes high-quality hydraulic components and strict assembly processes to guarantee system efficiency and long-term durability . This system powers the optional hydraulic hammers (models AR75/85/100), which operate at a flow of 50-110 L/min and an impact frequency of 350-800 Bpm, allowing operators to match the tool to the ground conditions.
Robust and Flexible Structure
The HKL300R boasts a well-engineered frame constructed from high-strength, fully national standard materials, ensuring excellent stability and a spacious operator environment . The sliding guide rail mast can be adjusted and features a ±5° lateral tilt, while the entire upper carriage can rotate a full 360° for exceptional positioning flexibility. The mast’s working height ranges from 4900mm to 7900mm, and it folds down for transport (4500-7500mm length).
Designed for Tough Terrain
Mounted on robust rubber tracks (350mm wide, 42 sections each), the machine is propelled by powerful (travel motors) with a (reduction ratio) of 1:54.4 and a maximum torque of 11,500 N·m. It achieves a travel speed of 3 km/h, providing reliable mobility on the uneven ground typical of construction and agricultural sites.
Built to Last
Superior manufacturing processes, including heat treatment of wear parts and stress-relieving welding of the main frame, minimize deformation and ensure long-term structural integrity under heavy use. Complete testing equipment validates the quality of each machine.
