A simplified H-frame construction and finite element analysis have helped us to create the ultimate heavy-duty mini excavator structure. The JCB 90Z therefore combines durability with confidence-inspiring stability.
The fully robot-welded high tensile steel boom and dipper is strengthened with internal baffle plates to offer a long and trouble-free service life. For added structural strength, our clean and elegant dipper design is constructed from just four plates.
With a heavy-duty boom cylinder guard, and the option of dipper and crowd ram guards, the JCB 90Z mini excavators enjoy maximum excavator arm protection, even during the toughest jobs.
Excavator hoses are safely routed through our heavy-duty kingpost, which is made to last using durable re-bushable pivots. By using the very latest O-ring face seals (ORFS) throughout the hydraulic system, we’ve reduced potential leaks too.
Premium componentry comes as standard on the 90Z mini excavators. The spec list includes JCB Diesel by Kohler engines, Nachi and Bosch-Rexroth hydraulics, and Bridgestone tracks.
To help these JCB minis perform anywhere, they’re equipped with high quality 450mm rubber tracks with interlocking links. Optional 450mm/600mm steel tracks are pre-drilled for rubber pads. There’s also the choice of dedicated Road Liner Pads (Bridgestone GeoGrip).
