Most demolition and scrap work in Ontario runs on an excavator or material handler with one of four attachments on the end.
Grapples pick up, sort and load. A demolition grapple has a wide jaw for rubble and timber; a scrap grapple, often with four or five tines, loads mixed ferrous into trucks and shears. Rotation is worth paying for; it saves the carrier from repositioning on every pick.
Shears cut steel. Mobile shears on an excavator process structural steel, pipe, rail and car bodies into furnace-ready sizes. They are heavy and hydraulically demanding, so the carrier has to be sized for the shear, not the other way around. Ask the dealer which shear class their carrier is set up for.
Pulverizers and crushers break concrete and separate rebar. A fixed pulverizer uses the excavator's stick and bucket cylinder; a rotating one has its own cylinder and jaws. Secondary crushing on site turns demolition concrete into fill and saves hauling.
Hammers and breakers do the primary breaking on heavy concrete and foundations. They are the hardest attachment on a carrier, so look closely at the boom and the hydraulics on any used machine that ran one.
Matching to the carrier. Every attachment has a carrier weight range and a flow and pressure requirement. Give the dealer your machine model and what you want to process, and ask for the attachment they would run on it, with the mounting and hydraulic kit included in the quote.
