Lightweight Manhole Box
A lightweight trench support system for forming a concrete manhole.
The Conquip Lightweight Manhole Box is a simple to assemble, two sided trench lining support system designed to be installed by an excavator using the ‘dig and push’ technique, or by simply carrying out the excavation and then lowering each box into place.
It is for use with smaller excavators or potentially backhoe excavators. The manhole box is available in approximately 3 metres length and is is generally suitable for trench depths of up to 3 metres.
Using a large excavator, or digging a bigger trench? Our Lightweight Manhole Box may suit your requirements better.
