Leader rigs: precision and power for piling projects

What is a leader rig?

Leader rigs are purpose-built piling machines, designed to install vertical elements into the ground with exceptional precision. They feature a vertical mast (the “leader”) that guides the piling hammer or vibratory driver, ensuring piles are driven accurately to the required depth and alignment.

Applications of leader rigs

Leader rigs are highly versatile and are commonly used for:

• Sheet piling: Ideal for retaining walls, cofferdams, and flood defence structures, leader rigs ensure sheet piles are driven vertically and securely, even in challenging ground conditions.
• King post installation: Used in temporary and permanent retaining systems, leader rigs provide the control needed to install king posts accurately, which are later infilled with precast concrete panels or timber lagging.
• Tubular steel piles: For foundations, marine works, and heavy civil engineering projects, leader rigs can drive large-diameter tubular piles with high precision and minimal deviation.

Key benefits of using leader rigs

• High accuracy: The rigid mast ensures piles are installed plumb and to exact tolerances, reducing the risk of misalignment and structural issues.
• Efficient setup and operation: Leader rigs are self-contained units, allowing for rapid mobilisation and reduced setup time on site.
• Adaptability to ground conditions: Equipped with vibratory hammers, hydraulic impact hammers, or rotary heads, leader rigs can be tailored to suit a variety of soil types and project requirements.
• Improved safety: With integrated handling systems and minimal manual intervention, leader rigs enhance site safety and reduce the risk of injury.
• Reduced environmental impact: Modern rigs are designed to minimise noise and vibration, making them suitable for urban or environmentally sensitive locations.
