Liebherr Container Cranes Ltd. recently supplied two units of the SC350T Straddle Carrier to Peel Ports in Liverpool. The Port has also reserved the option to purchase additional Liebherr Straddles later this year.
The development of the Liebherr Straddle Carrier is based upon the extensive knowledge and experience gained in over 40 years manufacturing container handling equipment. The Straddle Carrier complements the existing product range of Liebherr Port Equipment. The Port of Liverpool currently operates seven Liebherr Ship to Shore Cranes.
In keeping with the Liebherr design philosophy the Straddle Carriers are diesel electric and the electrical drive and control system has been developed by Liebherr. The design is based on well proven technology and high quality components as with the STS/RMG and RTG cranes produced by Liebherr. The Liebherr design brings new and innovative features to the Straddle Carrier market such as four axle steering and brake by wire. The use of proven container crane technology such as its electrical hoist winch design featuring external disc brakes is typical of the design approach. With the Hydraulics located at ground level it offers a more dynamic response to Steering and braking inputs from the driver which are independent of Engine Speed. The four axle Steering system with cylinder mounted sensors ensures a higher accuracy of the Steering system in both 2 and 4 wheel steering modes leading to reduced tyre wear. By removing the hydraulics from the Engine compartment and top platform the Fire Risk is also substantially reduced in this area. The driver’s cabin is ergonomically arranged to provide a comfortable and productive environment with intuitive graphical displays for monitoring all major components along with statistical information for operations.
The stability of the machine while cornering and the smooth control of the long travel drive while box positioning as well as the ability of the Liebherr machine to handle damaged boxes effectively are among some of the features well received by operators.
