For years now, Nemag has worked with the largest steel plants and dry bulk handling companies in the world. This cooperation enables us to continue to develop our products. A good example of this process is the Nemag Scissors grab, specifically suited for the large-scale handling of coal, ore, minerals, biomass, concentrates and bauxite. This product guarantees high productivity, long life-expectancy and low maintenance costs under all working conditions.

The Nemag Scissors grab combines speed, lightweight and stability on sloping surfaces to ensure the highest average productivity. This makes the use of trimming equipment, such as bulldozers or shovel loaders, practically unnecessary. Especially the excellent cleaning-up capabilities of the Scissors grab lead to considerable savings on the total unloading time and savings on the deployment of people and machines. This does not only lead to the highest average productivity, but also to the lowest cost per unloaded ton of material.

With its extremely efficient design, the Scissors grab combines a favourable distribution of forces in the construction with the advantages of easy operation. Nemag Scissors grabs stand out thanks to their excellent digging and filling capabilities, extremely short cycle times, long life expectancy and very low maintenance costs. While designing the Scissors grab, we took extreme working conditions and high occupancy degree of the installation into account.

Scissors grabs are available with every possible kind of opening direction and with diverse cable patterns: longitudinal, tranversal and diagonally opening in relation to the crane. To combat the emission of dust, the Scissors grab can also be fitted with environmentally friendly shells.

The added value of the scissors grab

  • Highest average productivity because it extends the free digging phase
  • Extremely favourable cleaning-up capabilities, reducing the cleaning-up phase
  • The favourable centre of gravity saves time because the grab does not topple over
  • Reduced risk of ship’s damage thanks to grab design and horizontal digging curve
  • Lower operational costs thanks to reduced deployment of trimming machines and staff
  • Very low maintenance costs per ton material handled
  • Grab can be changed without climbing into the grab
  • Specifically suited for use with automated gantry cranes

Characteristics

The Scissors grab is available with lifting powers up to 120 tons Safe Working Load. Volumes can exceed 60 m3, e.g. for coal. The Scissors grab is very suitable for handling (sticky) coal and ore, minerals, biomass, concentrates and bauxite. The Scissors grab is available with an open or half-closed shell.

Advantages

The Scissors grab has the highest average productivity and is known for its stability on sloping surfaces. It has excellent cleaning-up capabilities, very good digging and filling specifications and extremely short cycle times. The robust design guarantees long life expectancy and low maintenance costs.
