Invalid lifting trolley - has separate control box for all functions, e.g. lifting out of bed, operated by invalid

摘要

The separate control box, accessible by the invalid enables him to control all operations such as lifting him out of the bed, transporting him and lifting him over and into a bath, for example. The spacing of the prongs of the form forming the base of the motorised invalid trolley is adjustable to prevent tipping during lifting. The control box contains all the switches and push buttons to control all possible operations such as drive forward or reverse, turn left or right, raise or lower a jib arm holding the invalid, widening or narrowing the forked base or sounding an alarm signal. The max. voltage in the box is 12V. Three 12V batteries provide the power and are in the detachable drive unit. A possible development is radio control for calling the trolley by the invalid.
