Spider Crane — Compact Crawler Lifting Solution for Confined‑Space Works

Traditional large‑size cranes often face access limits on narrow job sites, indoor projects and complex‑terrain locations. The spider crane, also known as mini crawler crane, serves as a practical alternative for such challenging working conditions.
Featuring retractable multi‑leg outriggers and rubber crawler chassis, this machine can pass through narrow doorways and elevators when folded. Adjustable outriggers offer stable support on uneven ground, while rubber tracks help lower ground pressure to protect finished floors or pavement surfaces.
Equipped with hydraulic telescopic booms, spider cranes support diverse lifting heights and working radii. Dual‑power options (diesel and electric) allow flexible deployment: electric mode fits indoor low‑emission operation, and diesel mode suits outdoor field jobs. Wireless remote control enables operators to observe loads from proper viewing positions for convenient handling.
Common applications include glass curtain wall installation, indoor building renovation, factory equipment mounting, rooftop maintenance and municipal‑site lifting tasks. Multiple capacity options are available to match different project requirements.
If you need a lifting device for space‑restricted sites, spider cranes are worth your consideration.
