The Conquip Mechanical Manhole Ring Lifter is an adjustable clamping grab for crane-lifting and placing precast concrete manhole rings, cones, shaft sections and base units. The mechanism is operated entirely by the machine driver from the cab, so ground crew never need to enter the trench or working zone to couple or uncouple the unit. The grab adjusts to suit different ring diameters, covering the full range of standard precast manhole components from a single piece of equipment.
Key Features
- Single-operator placement direct from the machine cab
- Removes the need for ground crew to enter the trench during placement
- Adjustable jaws cover the full standard range of precast manhole rings
- Automatic release mechanism for hands-free uncoupling at depth
- 2500kg capacity covers full-height precast rings and base units
- Heavy-duty welded steel construction for repeated site use

Suitable Applications
The Mechanical Manhole Ring Lifter is standard equipment for drainage and utilities works requiring precast manhole construction. Common applications include surface water drainage, foul drainage, deep drainage chambers, pumping station shaft construction and sewerage projects. For lighter-duty applications using webbing slings rather than mechanical clamping, see the manual Manhole Ring Lifter; for individual ring lifts the steel-pin Manhole Ring Lifting Pin range may also be appropriate.
