Product Description

3/4" x 30" Expanding Rock Anchor

• Used as a heavy-duty anchor in solid rock.
• Anchor consists of two Malleable castings and a Triple Eye Anchor Rod.
• All components are hot dip galvanized to meet ASTM Specification A153.
• To install anchor, drill a 12" deep hole in solid rock, put anchor in hole, turn rod until anchor expands and wedges in the hole.
• Anchor diameter is 1-3/4".
• Anchor size expanded is 2-3/8".
• Hole diameter is 1-7/8".
• The harder the pull on the rod, the tighter it wedges into the rock.
• Ultimate strength is 23,000 lbs.

Rock Anchor
Expanding rock anchors provide strength and stability to rock and concrete structures, protecting them against problematic movement and collapse.
Inserted directly into the solid mass and expanded once inside, they transfer tension from the exterior to the interior of the structure, providing sturdy reinforcement at its core.
This strong and durable expanding rock anchor is crafted from treated steel and iron, which meets the necessary testing specifications.
expanding rock anchor boasts a triple guy eye, making it suitable for up to 3 guy strands. Its eye grooves are also contoured to minimise wear and tear to slack.
It offers long-lasting and reliable stabilisation against the onslaughts of both nature and man-made machinery. Suitable for use in a range of infrastructure, construction, and telecommunications projects.


Product Features:

• Galvanised steel anchor shaft
• Drop-forged triple guy eye
• Rust-resistant iron wedges
• Meets spec ASTM A15-C
• Contoured eye grooves
• Anti-corrosive materials
• Easy grip, solid handle
• Minimal maintenance

Hot Dip Galvanized (Complete with Rods) The malleable iron expanding rock anchor fits into a hole 1-7/8" or 2-3/8" in diameter, expands and wedges firmly against solid rock. When the anchor is expanded, the greater the pull on the rod, the harder the anchor becomes wedged. No lead, concrete or grouting equipment is necessary. Furnished complete with 3/4" and 1" rods, 15" to 8' in length. Anchors are painted black and the rods are hot dip galvanized.

An expanding rock anchor is an elongated engineering tool, usually made of a sturdy metal such as steel. They are used to transfer tension from the outside to the inside of a solid material such as rock or concrete. The purpose of this is to maximise the stability or the safety of the structure (or both).

Its design is a cross between a bolt and a screw. At the top end, it has a handle and an 'eye' to operate the anchor. At the lower end, it has two wedges, designed to expand outwards and pressurise inside the mass.

expanding rock anchors are utilised in a wide variety of industries that work with materials such as rock and concrete. These include infrastructure (e.g. the construction of bridges, tunnels, and highways), telecommunications (e.g. to support or protect cable suspension), and mining and refinery.
