Gully and Manhole Clamps

Our gully and manhole clamps are a three-way mechanical lifting set for precast concrete road gully pots, manhole rings and tapered cones. They grip securely over the top of the concrete rim and can lift sections up to 3 tonnes.

Typical Applications

You can use these clamps with an excavator or crane to offload precast drainage units from lorries and lower them into the trench:

• Trapped and untrapped precast concrete road gully pots
• Eccentric and concentric tapered manhole cones and reducer slabs
• Precast concrete manhole rings from 800mm to 2,000mm internal diameter
• Cut ring sections or chamber units supplied without cast-in lifting pin holes

Three-Way Camlock System

Our gully and manhole clamps comprise three C-shaped clamp heads hanging on flexible legs from a central master link. Because each clamp hangs on its own leg, you can fit them onto sloped or offset manhole cones that a rigid internal ring grab cannot hold.

There are no screw threads to wind in or out by hand. To attach, you simply slip the three open clamps over the concrete lip. As the operator takes up the weight on the machine, the camlock teeth close against both the outer and inner wall, gripping the section tightly.

Once the operator lowers the gully pot or manhole section onto its bedding and slacks off the slings, the latch on each head holds the jaws open. The operator can then lift the clamps straight off the rim. This differs from lifting with chains where a worker would be required to enter the trench in order to unhook things.

1.5 Tonne and 3 Tonne Models

We stock two sizes to match the weight and wall thickness of your concrete units:

• The 1.5 tonne (1,500kg) set fits wall thicknesses from 40mm to 120mm and weighs around 28kg, suitable for road gully pots, cones and standard DIN 4034 Part 2 manhole rings.
• The 3 tonne (3,000kg) set fits thicker walls from 60mm to 180mm and weighs around 40kg, built for heavy chamber bases, deep manhole rings (DIN 4034 Parts 1 and 2) and thick-walled cones.

Clamps, Ring Lifters or Lifting Pins?

If you are lifting gullies, tapered cones or concrete rings without pre-cast holes, these top-rim clamps are the right choice. Because the jaws grip over the top lip, there are no through-wall pin holes left to mortar up once the chamber is built.

For straight-sided cylindrical rings between 900mm and 1,500mm internal diameter, we also supply 2,500kg manhole ring lifters. If your rings already have cast-in side holes, we also sell manhole ring lifting pins in 25mm, 32mm and 35mm sets for loads up to 1,500kg, used with standard lifting chains.
