Been loading containers with bagged cement for a project up in Fujairah and the old hand pump we've been using to inflate dunnage bags is honestly destroying my shoulders, by the third container of the day I can barely lift my arm to sign the paperwork. The foreman told me to just deal with it but I'm the one who has to face the physio bill so I started poking around for alternatives. Found what looks like a proper dunnage bag inflator on a local supplier's site that runs off compressed air and has one of those trigger controls instead of the bicycle pump style handle we're currently wrestling with, and the idea of just hooking it up to the workshop compressor and filling a bag in ten seconds instead of ten minutes sounds almost too good to be true. My question for anyone who's upgraded is whether these things have a habit of over inflating and popping the bags if you zone out for a second, because the last thing I need is a loud bang inside a container followed by a very awkward explanation to the safety officer. Also does the pressure gauge actually stay accurate with all the dust floating around or does it clog up after a month?
