Hydraulic Hammer Interface For Loaders

-Allows to transform standard loader into secondary breaking unit a low investment cost.
-Allows to fragment oversized boulders efficiently, on site, prior to handling.
-Reduce blocking of galleries or draw point due to oversized rock blocks.
-Mitigate risk of damages on loaders and truck due to handling of oversized rock blocks.
-Mitigate risk of jamming and wear and tear of the crusher

-Increase machine versatility
-Increase productivity
-Reduce operating cost


Most underground mines face the challenge of moving oversized rock blocks. Whether that oversize is created from inaccurate drilling, blasting, or just not enough homogeneous grinding in the case of a block cave, large rocks can be very costly and extremely dangerous to deal with.

Oversized rock boulders affect mining operations and increase the cost of operations in many ways like:
• Inefficient loading operations
• Higher cycle time for hauling equipment due to higher waiting time and loading time
• Risk of damages and/or extra wear of loading and hauling equipment.
• Jamming and wear and tear of the crusher.
• Blocking of galleries or draw point.

Even in some mines, the oversize is dispatched to the waste dump, resulting on direct loss of ore.

In order to mitigate this problem, Sandvik has designed an interface system that allows to install an hydraulic hammer (Rammer®) on selected Loaders.

Hydraulic hammer installed on loader allows to efficiently fragment oversized rock blocks.

The Sandvik Hydraulic Hammer interface retrofit kit includes all needed parts to do the adaptation of a Rammer® hydraulic hammer on a loader originally equipped with conventional bucket, including new controls, hydraulic and electric components, hose and electric wiring harness, etc.
