Load lifting device 10 with platform 18, extendible support means 16 and at least one gas strut 30. The actuation means 24 for enabling extension of the support means 16 may be a pulley system (figure 5), which may be manually operable. The at least one gas strut 30 may tend to urge the support means into its extended position, and may be located within the support means. There may be two gas struts 30, 30 fixed relative to one another, and engaging in a common guide means 31. The support means may be vertically extendible, potentially comprising at least two elements, which may be concentrically nested housings 20, 22, linearly slidable relative to each other in telescopic manner. A portion of the actuation means 24 may be permanently fixed to one of the housings 20, 22 and to the platform 18. Figures 12 and 13 show an alternate embodiment using a scissor lift.
