Compact tracked cranes that pass through a standard doorway, set up on four outriggers and lift where a conventional crane cannot reach. The range runs from pop-up minis to the battery powered Eco-UNIC, all from UNIC. Available to buy, or to hire from our partnership fleet as operated or contract lift hire; see spider crane hire. Pair with our spreader beams for long or awkward loads.
Spider cranes are compact and track-mounted, so they can pass through standard doorways, work inside buildings and set up on floors that would not take a mobile crane. That access is the reason to choose one — capacity comes second.
Capacity depends entirely on outrigger configuration and ground conditions. A crane on fully extended outriggers on a prepared surface lifts far more than the same machine on partial spread indoors. Check the load chart for the configuration you can actually achieve on site.
Most models offer both engine and electric drive, so the machine can travel on its engine and then work on mains power indoors where exhaust fumes are a problem. Confirm the electrical supply available before planning on it.

Outrigger spread and ground conditions above all. Always work from the load chart for the configuration you can actually achieve, not the headline rating.
Yes. Most offer electric operation as well as engine drive, so they can work indoors without exhaust emissions. Confirm the power supply available first.
