Load handling equipment (10) has a longitudinally extending beam (11) supported by four legs (12, 13) each of which is joined to the beam by insertion into a sleeve (14), and there is a fifth sleeve (35) at one end which is hinged with respect to the beam (11), the arrangement being such that, upon erection of the equipment, the upper ends of the legs (12) of one of the pairs of legs may be inserted into sleeves (14) at one end of the beam (11), a third of the legs (13) being inserted into the fifth sleeve (35) at the other end of the beam (11) and being utilized to elevate that other end of the beam while the fourth leg (13) is inserted, the third leg (13) then being transferred from the fifth sleeve (35) to the third sleeve (14) so that the beam is then supported by two legs at one end and one leg at the other, and when in that position, the fourth leg being inserted into one of the fixed sleeves at the fifth component end of the beam, whereupon the fifth component can be hinged out again, the leg which has temporarily supported the beam end can be removed from the fifth component sleeve, and its upper end can be reinserted into the remaining fixed sleeve at the fifth sleeve end of the beam.
