Liebherr presents the new GMZ 180B, its largest clamshell to date. The 8.5 tonne attachment is specially designed for coal handling applications. With a capacity of 16 m³, fast loading and unloading processes are guaranteed.
Kirchdorf an der Iller (Germany), 26 October 2023 – Development of the GMZ 180B clamshell was triggered by an order from a customer in Indonesia for four new Liebherr LH 150 C Port Litronic handling machines. In order to manage the high handling volume in its coal mine, the customer was looking for a larger attachment compatible with the LH 150 C Port Litronic handling machines. The new, powerful combination from Liebherr, will enable the customer to load around 200 tonnes of coal into trucks equipped with large dump trailers in just 14 minutes.
The GMZ 180B grab is specially designed for fast handling of bulk materials. In terms of its dimensions, it is the largest clamshell ever manufactured by Liebherr, with a total weight of 8.5 tonnes and an overall height of 4.7 metres. The bulk shells themselves have a width of 3.2 metres. The capacity of the GMZ 180B is 16 m³ with an opening width of 4.8 metres. In just one loading cycle, large quantities of coal can thus be handled and incoming trucks can be loaded and unloaded more quickly.
The GMZ 180B is equipped with large and powerful cylinders that ensure fast opening and closing of the bulk shells and thus fast working speeds. Due to the pump summation of the LH 150 C Port Litronic, the GMZ 180B was given a flow rate of 570 l/min to ensure the cylinders can always be supplied with sufficient hydraulic oil. Thanks to sealed bearings on the cylinders, work is also possible in dirty environments and underwater. To reduce friction in the bearing points, floating bearings were installed. An optional piston rod guard for the hydraulic cylinders is available in addition to the grab itself.
The bulk shells on the new GMZ 180B are made of solid wear-resistant steel. Thanks to the use of high-quality materials throughout, the grab is extremely stable, durable and thus designed for a long service life. Perfect tolerances and generously dimensioned bearing surfaces result in gentle interactions between the individual components. Regular, automatic lubrication of all lubrication points is carried out by means of an optional central lubrication system.

From dust to top performance: Liebherr impresses at the České Štěrkopísky gravel plant
Dust, demanding operating conditions and extreme material loads: at the sand and gravel pit near Velká Černoc, Liebherr wheel loaders and mining trucks are demonstrating their full capabilities. Abrasive sand, uneven tracks and demanding multi-shift operation place the highest demands on both man and machine. It is not just performance that is crucial here – above all, robustness, reliability and efficient coordination between all machines are essential.
