HS2 revealed the final designs for the North Portal of the Chiltern Tunnel – the last of seven key structures for the high speed rail project’s longest tunnels. Once construction is complete, the seven ‘Key Design Elements’ will be the only parts of the tunnel visible to the local community.
Sandvik has decided to invest in a new production unit in Malaysia for manufacturing underground loaders and trucks. Equipment production is planned to begin in the fourth quarter of 2023 following factory upgrades and other site improvements. The investment is expected to total SEK 350 million over the coming three years.
Normet defines the future of underground transportation by launching the innovative Normet ElectroDynamic (ED) architecture and the XL ED platform
Normet is excited to announce the expansion of its product offering by introducing the XL platform together with the company’s latest technology innovation, the Normet ElectroDynamic® powertrain architecture, specifically designed to complement our new high-capacity platform and pave the way to the future of more sustainable underground operations.

Haver & Boecker Niagara adds the Cap & Slide and Pin & Anchor deck frame systems to its expanding line of lock-bolted deck frame technology. The new deck frames offer the availability of bolt-on convenience for pin and sleeve and groove style modular screen media. The innovative design of the lock-bolted deck frames was introduced at CONEXPO-CON/AGG 2023 and underscores Haver & Boecker Niagara’s ongoing commitment to being a total solutions provider for mining, aggregate and fertilizer processing operations by increasing efficiency and reducing operational expenses.
“The deck frames, whether Pin & Sleeve or Cap & Slide, provide the first line of defense against wear and can be exchanged individually,” said Duncan High, Haver & Boecker Niagara’s division manager of processing and equipment technology. “Beyond that, the rails can be replaced in 4-foot sections, allowing our customers to target and replace only those areas with high wear. This saves not only time but also expense.”
The narrow configuration of the new deck frames increases the open area for more throughput.
Lock bolts are used to provide a secure, weld-free connection that minimizes cost and wear. The rails require no special tools to repair or replace and can be installed 50% faster than traditional rail systems. Eliminating welding removes the need for a skilled welder, as well as the potential for accidents from cutting or grinding, and the chance of fire.
The Pin & Anchor deck frame incorporates laser-cut rails with polyurethane pins and anchors to secure the screen media to the deck rail. Designed to hold the media firmly in place, the pins and anchors can be individually removed and replaced as wear occurs, extending wear life and reducing downtime. The Pin & Anchor deck frame system accommodates any pin and sleeve style modular screen media.
Designed to work with any groove-style screen media panel, the Cap & Slide deck frame offers the same ease of installation and extended wear life as the Pin & Anchor design. The system features 8-inch-long polyurethane sections that cover the top and sides of the rail providing a barrier against abrasion and corrosion. The sleeve locks into the rail and is held in place with a polyurethane key. As individual sections show wear, they can be removed and replaced in small sections rather than changing the entire deck frame, minimizing cost and repair time.
