A spider crane is a compact tracked mini-crane whose outriggers fold out like legs, so it passes through a standard doorway, fits in an elevator and then lifts far more than its size suggests on stable footing. It is the answer for glass installation, indoor steel, atriums, restoration and any lift sealed off from a road. Kranes arranges spider crane rental, operated or bare, matched to the load and the access route. Tell us the weight, the final position and the tightest opening it must pass, and we return a quote with the right machine, rigging and the certified operation to complete the pick.
A spider crane (also spelled spyder crane) is a compact tracked mini-crane whose four outriggers fold out like legs to create a stable lifting base far wider than its travel footprint. Folded, it passes through a standard doorway, fits in a goods lift and crawls over finished floors on rubber or non-marking tracks; deployed, it lifts far more than its size suggests. Electric and bi-energy models run emission-free indoors, which is why spider crane rental opens up lifts no truck-mounted crane can reach.
The spider crane exists for access-restricted work. It handles glass and curtain-wall installation, interior structural steel, atrium and skylight glazing, plant and machinery moves, restoration and heritage work, and any pick sealed off from a road or a yard. Where the only way in is a corridor, a lift car or a temporary opening, the spider crane is often the single machine that can get to the load and place it precisely — without dismantling part of the building to bring a bigger crane in.
Specifying a spider crane means the load, the final position and — critically — the tightest opening and the floor loading on the route in. Kranes matches the machine capacity and dimensions to that access, operated or bare, and confirms outrigger spread and ground or floor protection at the pick. Spider crane rental runs by the day, the week or the project, with the route planned in advance so the machine reaches the work and lifts safely once it is there.
A small crane in a finished or occupied building still demands full certification and care. Kranes supplies spider cranes inspected and documented to CSA and provincial standards, with certified operators experienced in tight indoor picks and the rigging suited to delicate loads like glass. Tell us the weight, the destination and the narrowest point on the way in, and we return a quote with the right spider crane and the plan to complete the lift.
