Inspection Pits built for you


For most of us when we see an inspection pit it's already installed in the workshop floor, probably the old style, manufactured of brick or concrete, absolutely filthy, damp and wet with some sort of frame used as steps to get into it. On top of that lead light cables, extension leads and air supply hoses disappear into the pit like strands of spaghetti!!!

An Inspection Pit supplied by Multitune is completely the opposite, usually manufactured in "one-piece" (depending on design & dimensions) from 5mm thick steel having bright white gloss internal walls, walk-in steel staircase, sump for any spillages, compressed air-lines, low voltage power supply and bright LED or low-voltage lighting.

The lighting and high pressure airlines are mounted into a pre-fabricated pressed recess into the wall allowing a clear working area for the technician(s). This simple design eliminates accidental oil and grease spillages from sticking onto the lighting giving the pit a clean bright working environment always.

All our inspection pits will be manufactured and fully marked to the standard :                            BS EN 1090-2:2008 + A1:2011 Exc 2 and CE marked.

We can supply any steel pit to your needs, we are not restricted to the motor-trade only?

Manufactured to order, we have supplied washing pits, cattle watering tubs, chemical dips, cattle crossing tubs etc, etc.
