Spider Cranes for Confined Space Operations

Spider cranes excel in environments where space is severely limited. Their folding boom and retractable outriggers allow them to pass through narrow corridors, elevators, and rooftop access hatches. Once on site, the outriggers extend wide to create a stable lifting base without requiring excessive surrounding clearance. This makes them ideal for tasks such as placing HVAC units on rooftops or lifting machinery inside existing buildings.

The primary benefits include low ground pressure and zero tail swing, which prevent damage to finished floors and nearby structures. Unlike heavy truck cranes, spider cranes can be operated by a single person via a radio remote, reducing labor costs. They are frequently used in plant maintenance, bridge inspection, and cemetery monument setting. Their ability to lift precisely in cramped spots minimizes downtime and improves job site safety.
