days like these are why I would deff recommend a gripper with your tilty,
had to replace a failed filter bed - tank had never been maintained, prefilter in tank had been taken out and so consequently after months or years
of sludge getting in it, sand filter was blocked, so with gripper I could sit in a nice splatter free environment and dig to then dismantle old chambers/geotextiles/pipeworks and then later pick it all up and put it into truck for recycling, only the gripper got covered in sludge and not us
checked out @ 2ish - cos it was pretty hot !
