The gantry crane brings the lifting point to where there is no overhead crane: two uprights, a beam and a hoist. The three main families — fixed steel, mobile steel on wheels, dismountable aluminium — cover very different needs.
Fixed steel gantry crane
This is the answer for a settled workstation: high capacities, height to measure, the option of a travelling trolley on the beam. You choose it when the lifting point will not change over time — for example above an assembly bench or a treatment tank.
Mobile gantry crane on wheels
The wheels — braked, in polyurethane — let you take the crane to the piece rather than the other way round. Attollo models allow travel even with the load suspended, at low speed on a flat floor: ideal for workshops, maintenance and diework.
Catalogue capacities reach 5,000 kg; for special spans or heights the crane is designed to measure, on rails with powered wheels too.
Dismountable aluminium gantry crane
When the crane has to follow the team — sites, installations, work at the customer's premises — weight becomes criterion number one. The aluminium crane comes apart into components that travel in a van and goes back together in minutes with one to three people, with no lifting plant.
Typical capacities run from 250 to 2,000 kg with adjustable height: less than a steel crane, but with a versatility steel cannot offer.
How to choose, in three questions
First: is the lifting point fixed, or does it have to move? Second: do you need to travel the load while suspended, or is lifting on the spot enough? Third: does the crane travel with you or stay in the plant?
Fixed and heavy: steel gantry. In the shop, with the load to be moved: mobile gantry on wheels. On the road: dismountable aluminium. If in doubt, a comparative quotation on two configurations costs nothing.
CE rules and testing
Every gantry crane falls under Machinery Directive 2006/42/EC: CE marking, declaration of conformity, manual and overload testing. Attollo cranes leave the Milan workshop with the complete documentation.
