Liebherr unveiled a new piling rig to its leading customers from across the world last Friday night at its factory in Nenzing, Austria.
The unveiling of the LRB 355 piling rig was the finale to the company’s customer day that also saw the launch of two new duty cycle cranes – the HS 8130 HD and HS 8300 HD – and the LV20 sheet pile vibrator attachment.
“The focus of the development of the new piling rig was fuel efficiency,” explained Liebherr-Werk Nenzing managing director for design and development Holger Streiz. “The new design also features longer tracks for improved stability and direct mounting of the winches on the leader gives the operator a clearer view and helps to prevent cable issues during leader adjustment.”
According to Streiz, the rig is an all-rounder. “It is designed for any piling application, including full displacement piles,” he said.
Liebherr also said that the rig has bigger kinematics that allows it to operate over a wider area from one location. Another new feature on the rig is the ability to add counterweights to improve efficiency.
The 100t LRB 355 rig can be configured to give a maximum height of 33.5m. The standard rig comes with a 600kW Liebherr engine but this can be upgraded to 750kW to provide additional power to the BAT rotary drive, which delivers 450kNm of torque.
Another option on the LRB 355 is an elevating working platform for safe and easy access to the attachments and to the rotary.
