The SZA and SZM manhole clamps automatically adjust to the manhole cover – without the need for adjustments or risks. Ideal for contractors looking to work efficiently and safely.
From compact models to heavy-duty 4-clamp systems: our manhole clamps lift up to 4,000 kg, with built-in safety features like spring pressure closure and safety locking.
For coated, painted, or smooth concrete elements, the RSVG series offers rubber-coated clamps that prevent damage during lifting.
