Goliath Cranes

Goliath Lifting Cranes or Portal Cranes Explained.

Goliath cranes, sometimes called portal cranes, are similar to overhead travelling cranes (OHTC’s), but instead of running on rails at high level, or on a free standing gantry structure, they run on rails on the floor. One of the advantages of a goliath crane is the lack of support gantry rails can save money.

For better access, it is often preferred to use a goliath than have crane columns every 6 meters for traditional OTC’s, but you will have a floor rail to consider when purchasing your goliath crane. Crane floor rails are sometimes seen as a disadvantage, as fork trucks cannot drive over them, and people may occasionally trip on them. To prevent this, rails for goliath cranes are sometimes sunk into the floor. This involves digging out a small channel for the rail to be dropped into, and fastened down securely. We usually leave the top of the rail at floor level, to assist vehicle movement over the tracks and prevent the raised rail becoming a tripping hazard.

Sunken floor rails (image below) helps to reduce the trip hazard, and can be driven over with fork lift trucks. with sunken rail it can occasionally get contaminated with stones, leaves and other debris. Regular cleaning and inspections can avoid this as part of a maintenance program.

In addition, staff and visitors to site will need to be wary as a moving goliath crane can cause serious injury to pedestrians. Your site should have walkways and staff should wear high visibility clothing at the very least. Your safety officer will be able to advise you, and will know about restrictions you need to implement locally.

We purchased the goliath below and the client added a safety barrier, to prevent injury as people walked though a side door.
