Zusammenfassung:A lifting apparatus (100) for lifting vacuum pumping and/or abatement equipment, the lifting apparatus comprising: a plurality of rams (110a-110d) for engaging with equipment; a plurality of pumps (130a-130d) for pumping fluid to the plurality of rams to cause the plurality of rams to move equipment engaged with the plurality of rams; and a plurality of valves (120a-120k) for controlling the flow of fluid between the plurality of rams and the plurality of pumps, wherein the plurality of rams are connected to the plurality of pumps via the plurality of valves, wherein the lifting apparatus is operable in a first mode in which the plurality of valves are configured such that each of the plurality of rams is in fluid communication with each other ram, and wherein the lifting apparatus is operable in a second mode in which the plurality of valves are configured such that each of the plurality of rams is fluidly isolated from each other ram.
