Manhole Ring Lifting Pins

Manhole ring lifting pins allow you to lift precast concrete manhole rings with pre-formed holes using chain slings. We supply lifting pins for sale in 25mm, 32mm and 35mm sets, with Safe Working Loads up to 1,500kg.

Typical Applications

You can use manhole ring lifting pins with an excavator or crane to:

• Offload precast concrete manhole rings from delivery lorries
• Lower and bed chamber rings inside shored manhole excavations
• Handle BS EN 1917 and BS 5911 concrete rings cast with through-wall pin holes
• Build foul and surface-water sewer chambers, catchpits and deep drainage shafts

Gravity Toggle Lock and Release

Each pin has a steel shaft with an offset lifting eye at one end and a pivoted toggle bar at the other. To attach the lifting pins to a ring, align the toggle bar with the pin and push the pin from the inside of the ring outwards through the cast-in hole. Once the end of the toggle bar shaft clears the outside of the concrete wall, the bar drops under gravity and locks across the hole.

Once you have placed the ring and slackened the chains, simply flip each toggle bar so it is inline with the shaft and slide the pins back out.

Sizing and Chain Sling Pairing

Precast concrete manhole rings vary in wall thickness and pin-hole diameter according to the ring bore. You need a pin diameter that fits the cast-in hole closely, with a shaft long enough for the toggle bar to clear the outside of the wall completely:

• We supply 25mm pins as a set of 3 (750kg SWL) for walls up to 120mm thick, to fit a 3-leg chain sling
• We supply 32mm pins as a set of 3 (1,000kg SWL) for walls up to 150mm thick, to fit a 3-leg chain sling
• We supply 35mm pins as a set of 4 (1,500kg SWL) for walls up to 175mm thick, to fit a 4-leg chain sling

Always use the full set of three or four pins together (never lift on a single pin or two pins), and keep the chain sling legs within 60° of vertical. Only use the pins to offload and place one ring at a time, never to lift stacked rings together or travel suspended loads across site.

Lifting Pins vs Mechanical Ring Lifters

Manhole ring lifting pins are for concrete manhole rings with pre-cast through-wall pin holes. If your rings do not have pin holes, use our self-clamping manhole ring lifters or gully and manhole clamps instead.
