<p>A Hydraulic lift whose components do not require a separate place for the Machine room. This device consists of a power unit (12) incorporated inside the hoist way (9) and characterised in that the valve (13) placed on the lid of the power unit (16) can shift from its original position by means of a mechanism applicable outside the hoist way (15). Thus, the control panel (17) and the valve shift mechanism (15) can be placed inside one cabinet or more (18) at the landings of the lift. The application of the shift mechanism (15) enables the entry and exit of the valve (13) from the hoist way (9) when carrying out maintenance-monitoring works and when releasing trapped passengers.</p> |
