  • How to Build the Perfect DIY Gantry Crane

    Load capacities usually fall into four different categories: up to 500 pounds, up to 1,000 pounds, from 1,000 to 2,000 pounds, and a full two tons plus. Generally, the higher the load capacity, the higher the price tag of building a gantry crane, so keep that in mind when balancing your lifting needs and your budget.
