Abstract:
A lightweight winch suitable for industrial applications has the motor assembly self-centered with a housing within the winch drum where it may be easily accessed and removed from the winch drum. The winch drum is supported by a bearing means capable of bearing heavy loads in addition to contributing to a compact profile of the winch. The winch comprises an improved, non-load bearing levelwind mechanism for evenly winding cable about the winch drum.
Abstract:
A wireless remote forms a two-way radiofrequency (RF) communication network with a winch control module that allows the wireless remote to control both the winch and additional vehicle accessories through the winch control module. Further accessory control modules allow the control of more accessories utilizing the wireless remote by way of RF communication. Feedback from either the winch control module or the accessory control module is sent back to the wireless remote to allow the operator to view the current operating conditions of the winch or accessories.
Abstract:
A winch drive assembly includes a drum having a cylindrical spool located axially between a first hollow annular flange and a second substantially circular flange having a central axle. A hydraulic motor has an inner stator and an outer rotor, the outer rotor of which releasably engages the first hollow annular flange of the drum. A braking system is positioned adjacent the outer rotor of the hydraulic motor and a support member releasably engages the central axle of the second flange of the drum.
Abstract:
A hoist (210, 334) includes a platform, a drum (214, 328), and a motor (212). The drum (214, 328) is supported by and configured to rotate with respect to the platform, and the motor (212) is coupled to the drum (214, 328) and configured to rotate the drum (214, 328). The hoist (210, 334) further includes a shaft (216) having a splined section (240) and an interlock system (228, 330) configured to constrain rotation of the shaft (216). The shaft (216) is coupled to at least one of the drum (214, 328) and the motor (212), and communicates torque between the drum (214, 328) and the motor (212). The interlock system (228, 330) includes a keyed ring (236) and an arm. The keyed ring (236) is configured to slide onto and engage the splined section (240) of the shaft (216). The arm extends from the keyed ring (236) and is configured to provide leverage to limit rotation of the keyed ring (236), thereby interlocking rotation of the shaft (216) when the keyed ring (236) is engaged with the splined section (240) of the shaft (216).

According to the invention, said assembly (1) also comprises: -a splined shaft (15) secured to one end of the worm (6); -a pocketed wheel (21) with inner and outer splines, engaged on the splined shaft (15); -an elastic member (22)between the pocketed wheel (21)and a stop piece(23); -a drive wheel (20) with a splined hub, with which the pocketed wheel (21) is capable of engaging rotationally; -a back-up motor (35), capable of rotating the drive wheel (20).
Abstract:
A winch includes a rotatable drum. A cable is wound onto the drum in one rotative direction and off the drum in a second rotative direction. A sealed axial flux permanent magnet drive motor includes a drive shaft selectively rotated by the motor in either direction of rotation. A gear train interconnects the drive shaft and the drum for rotatably driving the drum at a reduced rotative speed relative to the motor shaft. The motor can apply regenerative braking. A spring- applied electric release brake is connected to the drive shaft to apply a braking force to prevent rotation of the drum. A connecting shaft connects the gear train to the rotatable drum. The connecting shaft includes axially spaced splines that reduce the disparity in the gear train and drum centerlines to thereby reduce gyration therebetween. The drum can be made partially from carbon fiber to reduce the weight thereof.
Abstract:
Ein Portalhubwagen (1) zum Einsatz in Containerterminals und für allgemeine Transportaufgaben hat ein Rahmengestell (2), ein Lastaufnahmemittel (4), das zwischen dem Rahmengestell (2) hängt und mit einer Last, vorzugsweise einem Container (7), verriegelbar ist, Fahrträger (3), die am unteren Bereich des Rahmengestells (2) angeordnet sind und jeweils eine Vielzahl in einer Reihe angeordneter Räder (11) aufweisen, und ein Hubwerk (8), mittels dem das Lastaufnahmemittel (4) vertikal bewegbar ist und das Hubwinden und zumindest eine Antriebseinheit aufweist, wobei zwischen den Hubwinden und der zumindest einen Antriebseinheit eine Bremsvorrichtung angeordnet ist. Um zu ermöglichen, daß für die Bremsvorrichtung in Großserien herstellbare Standardbauteile mit hoher Betriebssicherheit eingesetzt werden können, wird vorgeschlagen, daß die Bremsvorrichtung als luftgekühlte Trockenbremse ausgebildet ist und auf der schnellen Seite eines zwischen der Antriebseinheit und der Hubwinde angeordneten Getriebes sitzt.
Abstract:
Изобретение относится к области гидрологии и рыбоводства и может быт использовано в различных акваториях озер, морей и океанов для погружения подъема научно-исследовательской аппаратуры и оборудования для выращивани морепродуктов в натурных условиях. Существо изобретения заключается в том что в СПУ, содержащее барабаны большого и малого диаметров, установлен обра тимый редуктор. Работа редуктора обеспечивает, необходимое для заданной глу бины, передаточное отношение между быстроходным и тихоходным валами, н которых жестко закреплены соответственно барабаны большого и малого диамет ров. Это позволяет увеличить скорость вращения быстроходного вала с барабано большого диаметра и уменьшить скорость вращения тихоходного вала с барабано малого диаметра. При погружении СПУ редуктор работает в режиме мультиплика тора, при этом функцию двигателя выполняет перемещаемый груз. При всплыти редуктор работает в обычном режиме, при этом функцию двигателя выполняе поднимающееся к поверхности СПУ, имеющее избыточную положительную пла вучесть.
Abstract:
Hydraulic assembly for controlling and driven of small hydraulic units, especially clutch and brake cylinders (551, 552) of a forestry winch (99), comprises at least a reservoir (510) for hydraulic media, a pump (500) for producing a required pressure of said hydraulic media as well as a control unit (550) consisting of a control valve 8555) as well as of at least one cylinder (551, 552). According to the invention a hydraulic circuit of the hydraulic assembly includes a piston pump (500), which is at the one hand via a non-return valve (540), which allows flowing in a direction away from the pump (500) but not also towards said pump (500), hydraulically connected with a control unit (550) and a reservoir (510 ) of hydraulic media, and on the other hand either via a switching valve (530) with integrated non-return valve (535), which allows flowing towards the pump (500) but not also in the opposite direction, in a serial manner into a hydraulic circuit together with a pressure storage tank (520) and the non-return valve (540), or by exceeding a pre-defined pressure by means of automatically shifting of the switching value (530) into a hydraulic circuit, which includes said pump (500), a switching valve (530), a control unit (550) and said non-return valve (540), which are hydraulically interconnected in a serial manner. Such assembly excels in extremely small overall dimensions, small quantity of a hydraulic fluid and low hydraulic loss.
