A winch (100) with integrated lighting can include a frame 102, a cable drum 104 rotatably supported by the frame, a drive motor 106 operatively connected to the cable drum, and an electrical module 108. The electrical module can include a housing with first and second end caps 122 coupled to the housing. An elongate light guide 124 can be mounted to the housing between the housing and the cable drum with one or more drum light sources 138 connected to the elongate light guide.
摘要:
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.

A system arrangement for the drive train of lifting mechanisms, such as crane lifting mechanisms, is disclosed. The system arrangement includes at least one drive motor (1, 1′), at least one cable drum (2, 2′) connected thereto, a reduction transmission (3) arranged between the drive motor (1, 1′) and the cable drum (2, 2′), an automatic overrun shutdown freewheel (6), and at least one safety brake (4, 4′). To optimize such a drive train, at least one active motor locking assembly (5, 5′) is utilized to hold the load when the drive motor (1, 1′) is decelerated electrically to a rotary speed of zero. The active motor locking assembly is utilized instead of at least one passive operating brake.

A system for hoisting a load on a drilling rig includes: a hoisting means having an elongated hoisting member and an elongated hoisting member drive means; a drill string rotation means suspended from an end of the elongated hoisting member; a support structure having a first side and a second side and being adapted to support at least a portion of the weight the drill string rotation means; a first elongated hoisting member guiding means connected to the support structure; and a counterweight connected to the elongated hoisting member at the second side of the support structure. The elongated hoisting member is reeved over the first elongated hoisting member guiding means from the first to the second side of the support structure. The drill string rotation means is suspended from the elongated hoisting member at the first side of the support structure
摘要:
Die Erfindung betrifft eine Winde (10) zum Auf- und Abwickeln eines Zugstranges (12), mit einer Wickeltrommel (22), die um ihre Mittelachse (A) derart drehbar ist, dass der Zugstrang (12) in um die Wickeltrommel (22) herum verlaufenden Windungen auf- und abwickelbar ist, und mit einem Drehaktor (20) zum Antreiben einer Drehung der Wickeltrommel (22), wobei die Wickeltrommel (22) in Bezug auf eine Basis (52) der Winde (10) längsbewegbar entlang ihrer Mittelachse (A) angeordnet ist. Es ist eine sich in der Mittelachse (A) erstreckende Gewindestange (28) mit einem Außengewinde (30) vorgesehen, wobei die Wickeltrommel (22) mittels eines Gegengewindes (36), welches in das Außengewinde (30) eingreift, um die Gewindestange (28) verdrehbar angeordnet ist.
摘要:
A motor assembly includes a three-phase asynchronous machine equipped with three stator phases, a capacitor assembly to establish self-excited generator operation of the asynchronous machine, a load resistor assembly to establish resistive load for self-excited generator operation of the asynchronous machine, and a load resistor switch which is arranged to connect the load resistor assembly to the stator phases. The load resistor assembly is asymmetrical.
