The Spider Excavator
A machine that walks where others can’t roll.
Four hydraulic legs, 157 horsepower and a footprint light enough for alpine meadows. This is the Kaiser walking excavator at the heart of everything we do.
Wheel-and-leg design
Built to stand level on ground that isn’t.
Each of the spider’s four legs ends in a wheel, paw or claw and is planted independently. The machine levels itself on slopes, straddles ditches and grips rock — then digs, lifts and reaches like a conventional excavator from a platform nothing else could hold.
A 157-horsepower Perkins turbo diesel drives it all, with up to 8.2 metres of reach and six metres of digging depth. It’s precise enough for finished landscaping and strong enough to set power poles and place rip-rap — all while running on fully biodegradable hydraulic fluid.
