New Swellex Bolt Tool with Improved Grip Strength Available

Safety and reliability are crucial in the demanding world of mining and tunneling. When it comes to Swellex rock bolt expansion, choosing the right tools can significantly impact your operations. For decades, the DYNASET HEU Hydraulic Expansion Unit has been the trusted choice for tunneling professionals, offering a powerful and versatile solution for even the most challenging projects. Dynaset now expands its offering with a revolutionary new rock bolt expansion tool that uses hydraulic oil pressure for bolt gripping, further enhancing safety, efficiency, and productivity.

What is the HEU Hydraulic Expansion Unit?

The DYNASET HEU Hydraulic Expansion Unit is used as a swellex bolt installation pump. It utilizes the hydraulic power of mobile machinery to expand Swellex rock bolts securely. Generating up to 300 bar of water pressure with the sequence-controlled patented DYNASET HPW High Pressure Water Pump, its adjustable pressure level and easy operation make it compatible with various bolt sizes. Also, the automatic pressure monitoring guarantees optimal expansion for each bolt. Previously paired with a pressurized water-based bolt tool, the Dynaset now offers the advanced option for even more outstanding performance. The new bolt tool uses hydraulic oil pressure for bolt gripping, which it gets from the base machine with a Dynaset-made valve combination.

The new tool uses hydraulic oil pressure to grip the swellex bolts and is used with expansion bolt installation rigs. The selection covers 30 and 40-millimeter tools. The tool has ports for high-pressure water for expanding the bolts and hydraulic oil from gripping them.

The New Hydraulic Rock Bolt Expansion Tool:

Dynaset presents a game-changing rock bolt expansion tool, complementing the existing water-based option. While the existing tool remains available, the new hydraulic-oil-powered version elevates bolt installation to a whole new level. Designed for use with rock bolt expansion robots, this innovative tool utilizes hydraulic systems’ oil pressure to grasp the bolt firmly, reaching an impressive 350 bar of hydraulic oil pressure. This translates to unparalleled reliability and unprecedented adhesion. Furthermore, like the previous tool, the new one seamlessly works with 30- and 40-millimeter Swellex bolts, offering broad compatibility.

New Tool to Supplement HEU Hydraulic Expansion Unit

The DYNASET HEU Hydraulic Expansion Unit and the new rock bolt expansion tool represent a powerful combination for improved safety, efficiency, and productivity in mining and tunneling operations. This robust, safe, and reliable solution ensures secure and consistent bolt installation, even in demanding conditions.
