What kind of surfaces can these cranes operate on?

Spider Cranes are ideal for uneven, rough, or sloped surfaces thanks to their independently adjustable outriggers. They can set up securely on stairs, rooftops, and even scaffolding platforms if properly supported. Mini Crawler Cranes are designed to operate on firm, level ground, though some models can handle mild inclines. For loose or muddy ground, wider tracks or ground mats may be required.
