KAISER — walking excavators: history, models, spare parts
KAISER — walking excavators: history, models, spare parts
Brand history
Country of origin: Liechtenstein / Austria
Founded: 1913
Since the mid-1960s KAISER has engineered walking excavators (“spiders”) designed for extreme sites: steep alpine slopes, riverbeds and wetlands. The 1965 pioneers evolved into today’s benchmark machines for off-road earthmoving and water engineering.
Products & engines
– Focus: walking (spider) excavators.
– Engines: primarily Perkins and Cummins, configured for high torque, steep-angle work and high altitude operation.
– Undercarriage: telescopic legs, auxiliary wheels/tracks, powerful hydraulics and superior stability on slopes.
Market size & position
KAISER stands among the two global leaders of the walking excavator niche (alongside Menzi Muck), being a de-facto standard for alpine, river and swamp applications.
Affiliations & acquisitions
Organic growth within the KAISER group (Liechtenstein/Austria manufacturing footprint). The brand built its position through continuous product improvements and partnerships with mountain and riverwork contractors.
Highlights
– Wading up to ~2.5 m and working on ~100% slopes (~45°).
– Modular legs and accessories (winches, auxiliary tracks/wheels, raised cabs, flotation kits) for extreme access and safety.
– Allroad configurations enable road travel in selected regions/variants.
Types & models (overview)
S-series (walking excavators):
– S1 — ~6.5 t: ultra-compact spider for streams and steep slopes.
– S2 — ~7.5 t: versatile all-rounder for mountain, forestry and drainage jobs.
– S10 — ~10 t: higher hydraulic output for heavy tools (hammers, shears, drills).
– S12 Allroad — 10–12 t: flagship, high-mobility variant for mixed on-/off-road travel; broad option packs for river and alpine work.
– Options: boom/arm lengths, telescopic/rotating legs, auxiliary tracks/wheels, winches, raised cabs.
Spare parts
Kaiser spare parts — matching by model/VIN/SN. Parts for Kaiser walking excavators (S1/S2/S10/S12): cab glass, hydraulics (hoses, valves, cylinder seal kits), leg system components (pins, bushings, bearings), electrics/controls, attachments and REDX filters.
