'' Mobile working device with a height-adjustable working

platform »

The Ieueruiig refers to a mobile work device with a height-adjustable work platform _? this serves ₅ high-altitude assemblies, installations ₃ maintenance work on iran systems, painting work on ceilings and. Vaults etc. ireistehena in the space to be able to carry out. The purpose of the hiring was to create a device that is easy to manufacture and does not require any power sources to operate, so that it can be used anywhere.

The construction of the implement according to the hay is characterized by a telescopic rod made of lattice masts of such a cross-section and with such a cross strut arrangement that the hooks at least ε ~ αί one side are to be used as a ladder. For this purpose, a triangular cross-section is preferably chosen for the lattice masts forming the telescopic rod = the extension and retraction of the telescopic rod is carried out by one or more cable pulls ₉ which can be operated, for example, by a hand crank »

3? The! Chassis

Equipped with three extension arms offset by 120 °, their ^ Either has a high-adjustable stand stamp = the 3ΐεηα strength can still dpnn through the extension arms hinged side supports are increased.

The implement according to the innovation is preferred set up in such a way that it can also be moved in a lying position. Aen can be avoided, for example, through low ^ door openings to be disabled in the application. This also makes it easier to park the aerates. To this end if the telescopic pole is equipped with its own ötand base, which is easily detachable attached to the laiirgeKtell in order to As I said, move the structure and be able to move it onto your chassis in a warranted position.

On the drawing, the subject of the inflation in different views shown, for example

The working device shown has three in each other sliding g-ridge masts 1, 2 and 3? the triangular cross-section have and are mounted on a chassis 4 by means of plug-in hinges 5 in order to release the structure from the chassis and to be able to move it in a horizontal position on the chassis »The telescopic frame is supported by three side supports 6 supported on the chassis or its extension arms are hinged *

The work platform 7 is on the inner lattice mast 1 mounted, and projecting in one direction, in order to accommodate every mounting point even with walls hindering the accessibility beciuen to be able to achieve.

The iT.hrge & tell 4 runs on two fixed shoulds 9 and one movable EoHe 1C. The chassis is supported by extendable, i.e. height-adjustable stana stamps 11, with their Help the device set up vertically γ / he can.

Each a separate cable 12 is used for height adjustment, the lower pulleys 14 are each provided with a crank 13 repluggable to use. Mind you, a single cable pull can also be used for the two inner lattice masts. The respective height adjustment is made by Easter 15? as they are common with rope ladders., made. Adjustable runners 8 are used to guide the lattice masts T and 2 »

The design of the implement according to the fire the advantage that the lattice masts as a result of their chosen crossbar At the same time, the arrangement of ladders, which enable the worker to ascend and descend from the platform - above all else even in danger enmoment en - enable-
