Abstract
A portable gantry crane formed of composite members includes a composite material I-beam. Two or more support members are formed of a composite material and each support member supports the I-beam when the portable gantry crane is in an upright position. Two or more end housings are included, each end housing enclosing a top end of one of the two or more support members and coupled thereto using adhesive. A plurality of latch structures are coupled with the I-beam, each latch structure including a latch, and each end housing having a latch receiver, each latch in combination with a latch receiver allowing one of the latch structures to be releasably fixedly coupled with an end housing. In implementations a plurality of latch structures are coupled with the I-beam, each latch structure having a latch structure enclosure and each latch structure enclosure at least partially enclosing one of the end housings.
