BEARING ELEMENT WITH WEIGHT MEASUREMENT FOR LIFTING PLATFORMS
The invention relates to a bearing element (5) for lifting platforms, which consists of displaceable part of a bearing arm (1) of a load-receiving element of a lifting platform and on the ends thereof, that protrude from the carrier (3), a vehicle receiving element (8, 13, 19) is disposed. Said invention is characterised in that at least one annular shaped recess (28), in particular in the shape of a groove, is arranged on the upper side (26) of said bearing element (5), in which at least one vertically displaceable transfer element (29), that seals a pressure chamber (30) that is filled with a hydraulic fluid (31) and that is disposed below, is arranged and pressure is produced in the pressure chamber (30), said pressure being characteristic to the weight (11, 16, 33).
Bearing element (1, 2) which is intended for lifting platforms and can be arranged between a carrying member (3, 19) of the lifting platform and a vehicle which is to be raised, wherein the bearing element (1, 2) can be moved away from the carrying element (3, 19), characterized in that the bearing element (1, 2) rests at least on a vertically displaceably arranged transmission element (9) which seals a pressure chamber (10), located above the transmission element (9) and sealed with a hydraulic fluid (11), and generates, within the pressure chamber (10), a pressure which is characteristic of the weight (14) resting on the bearing element (1, 2), and in that the pressure chamber (10) has an annular recess (8), in particular a groove, which is sealed by the likewise annular transmission element (9).
The invention relates to an elevating platform case (1) for underfloor elevating platforms. Said elevating platform case (1), into which parts of elevating platforms are integrated, comprises an opening (9) for tubes, electric wires, control wires, and supply pipes, as well as a receptacle (17) which is directly or indirectly mounted on the opening (9). The opening (9) is preferably located in a sidewall (8) of the elevating platform case (1) such that workshop air (26) that flows through the opening (9) also has to flow through the receptacle (17) to reach the interior of the elevating platform case (1). The receptacle (17) has at least one opening (29) into the elevating platform case (1) and contains at least one type of drying agent (24) and/or at least one type of material, e.g. bonded fabric particles (25), which is suitable for absorbing moisture from the air and/or water.
The invention relates to a built-in box (1) for underfloor lifting platforms in which are mounted parts of lifting platforms, characterized in that a set of drying agent consisting of a drying agent mat (14) and a multi-chamber bag (27) is positioned in free selectable amounts and combinations in the built-in box (1) and is fixed to said built-in box (1) or to parts of the lifting platform by means of a fixing element (17, 31) and can be easily and rapidly exchanged.
