Abstract:
The lift has dual-screw lifting assembly (A) installed inside the three-modular telescopic column (B). Lifting assembly (A) has spindle drive screw (1) coupled via gear (6) with electric motor (5) and threaded part driven into sleeve screw (2), and its external thread engages with nut of actuator (9) of telescopic column (B). Actuator (9) and embracing it central module (8), are run coaxially and along the fixed external module (7). Bracket (C) of lifted object (20) is fitted to actuator (9). The cross-section of the wall of external (7) and central (8) module is in the shape of regular polygonal geometric figures, similar to each other and actuator (9) is similar to them in shape or is round. Module guides (7, 8, 9) are made up of linear double-row, ball bearings (10), mounted on axes of symmetry of cross-sections and accordingly with external (11) raceway and internal (12) raceway rail to the neighboring wall surfaces.
Abstract:
A telescopic multistage lifter (1) is disclosed comprising a fixed tubular element (2) closed at one end by a flange (3) and a number of mobile tubular elements (4, 6, 8), each closed at one end by a respective flange (5, 7, 9) and arranged coaxial one inside the other and within the fixed tubular element (2). Screw like means (10, 11, 12) are connected to each one of the flanges (5, 7, 9) of the mobile tubular elements (4, 6, 8) belonging to a corresponding kinematic chain (C1, C2, C3) coupled to a motorized unit (13), which are suitable for telescopically and simultaneously extracting each mobile tubular element (4, 6, 8) from the matching tubular element which contains it.

Die Erfindung betrifft auch ein Transportfahrzeug, insbesondere ein fahrerloses Transportfahrzeug, umfassend eine Antriebseinrichtung, einen elektrischen Energiespeicher zur Versorgung der Antriebseinrichtung sowie eine Steuereinrichtung zur Steuerung der Antriebseinrichtung und eine erfindungsgemäße Hubvorrichtung (10).
Abstract:
Wagenheber, dessen Hubelement (11) gegenüber einem Ständer (8) verfahrbar ist, und mit einem Gewindetrieb, der eine Gewindespindel (2, 15) und eine auf der Gewindespindel (2, 15) angeordnete Spindelmutter (4, 16) aufweist, wobei eine Relativdrehung zwischen der Gewindespindel (2, 15) und der Spindelmutter (4, 16) in eine Längsverschiebung zwischen der Gewindespindel (2, 15) und der Spindelmutter (4, 16) entlang einer Spindelachse für eine Hubbewegung des Hubelelementes (11) umgewandelt wird, wobei als Gewindetrieb ein Planetenwälzgewindetrieb (1, 14) vorgesehen ist, dessen zwischen der Spindelmutter (4, 16) und der Gewindespindel (2, 15) angeordnete Planeten (6, 17) in Wälzeingriff mit der Gewindespindel (2, 15) und der Spindelmutter (4, 16) stehen.
Abstract:
A supporting device includes an upper tube (10A), an inner tube (20A), a transmitting system (30A) and a shoe (40A). Said transmitting system (30A) is mounted on the top of the upper tube (10A). Said inner tube (20A) is cover-placed inside the upper tube (10A), the top of the inner tube (20A) is connected to the transmission (30A) and the bottom of that is connected to the shoe (40A). The transmitting system (30A) is mainly composed of at least one less teeth difference transmission (1A), a cone gear pair and a screw (6A). The less teeth difference transmission (1A) is connected to a cone gear (31A), and the cone gear (31A) is connected to the screw (6A).
Abstract:
A linear jack includes a first outer sleeve, an inner sleeve disposed at least partially within the first outer sleeve, a second outer sleeve disposed at least partially within the inner sleeve, a translating screw disposed at least partially within the second outer sleeve, and a cover sleeve coupled to the translating screw. The first outer sleeve is threadedly coupled to the inner sleeve. The second outer sleeve is threadedly coupled to the translating screw. The translating screw is disposed at least partially within the cover sleeve. The cover sleeve is configured to translate with the translating screw.
Abstract:
A pipe jack or jack mechanism. The jack mechanism can include a base structure that can include a substantially vertical support member and a plurality of legs angularly disposed therefrom. An elevation member can be configured to move within the substantially vertical support member. A safety ring that can be generally circular can be disposed about an outer perimeter of the elevation member and can extend outwardly therefrom. An annular lock can be adjustably disposed about the outer perimeter of the elevation member and can be positioned below the safety ring. A stop gap can be positioned between the safety ring and the annular lock. A block cap can be disposed on a bottom portion of the substantially vertical support member to prevent the elevation member from extending beyond an end of the substantially vertical support member.
Abstract:
A windshield installation device for replacing automobile windshields. The device includes a stabilizing assembly, an adjustable shaft assembly, and a foot assembly. The stabilizing assembly includes a suction member configured to be removably coupled to the windshield. The adjustable shaft assembly extends between the stabilizing assembly and the foot assembly and includes an outer tube configured to receive an inner tube. The inner tube is slidable relative to the outer tube to adjust a distance between the stabilizing assembly and the foot assembly. The inner tube is rotatable relative to the outer tube to secure the inner tube to the outer tube. The foot assembly includes a foot body and a threaded shaft coupled to the foot body and the inner tube for further adjustment of the distance between the stabilizing assembly and the foot assembly.
