Liebherr calls its new battery-powered LB 30 is identical to the conventional version, with the added advantage of zero emissions. It says the LB 30 can be used in all common deep foundation applications, but operation is extremely quiet with no exhaust fumes, making it ideal for work in noise-sensitive regions. Charges with conventional jobsite electric supply and operation can continue as normal during charging. Designed for working time of 4 hours in Kelly operation.
