Hydraulic Cranes
Maintainer’s hydraulic‑powered crane family ranges from compact 3,500‑lb units to 14,000‑lb heavy lifters, all designed around the industry‑standard 14.75" × 14.75" bolt pattern for easy body integration. Every model pairs dependable planetary winches with proportional wireless control, delivering smooth, precise handling in construction, maintenance, municipal and utility applications.
Maintainer hydraulic cranes combine long‑reach booms (16 ft – 34 ft) with high foot‑pound ratings (15,000 – 90,000 ft‑lb) to give crews more capacity without adding excess weight. Short‑tower H‑Series models serve service‑truck envelopes, while the numerically‑named 65‑, 75‑, 85‑ and 100‑Series expand lifting power up to 14,000 lb. A standard 12 V self‑contained power pack (3 gpm) and thermal‑protected motor keep cycle times quick and components safe.
