International Classification:

B66C 2300

US Classification:

414685, 414700, 414722

Abstract:

A linkage assembly for connecting an implement to a frame of a work machine which provides greater visibility for an operator of the work machine is disclosed. The linkage assembly includes a box-boom lift arm having a frame end portion and an implement end portion, wherein (i) the frame end portion is pivotally coupled to the frame, (ii) the implement end portion is pivotally coupled to the implement, and (iii) the frame end portion includes a first extension and a second extension spaced apart from each other so as to define a first lever space therebetween. The linkage assembly also includes a lift cylinder having a frame end and a lift arm end, wherein (i) the frame end is pivotally coupled to the frame, and (ii) the lift arm end is pivotally coupled to the box boom lift arm. Moreover, the linkage assembly includes a rear tilt link having a first end and a second end, wherein the first end is pivotally coupled to the frame. The linkage assembly further includes a-rear tilt lever having a cylinder end and a link end, wherein (i) the link end is pivotally coupled to the second end of the rear tilt link, (ii) the rear tilt lever is pivotally coupled to the box boom lift arm at a location which is interposed between the cylinder end and the link end, and (iii) the rear tilt lever extends through the first lever space.

Abstract:

A maritime drift control system comprising a vessel movement detection unit, for detecting an actual vessel speed and direction, and a vessel movement control unit with a drift controller for controlling operation of at least one propulsion device of a vessel. The maritime drift control system comprises a drift error generator for generating drift error signals depending on a predetermined speed limit and the actual vessel speed. The drift error generator is connected to the drift controller to transmit the drift error signals to the drift controller. The drift controller uses the drift error signals to compute and transmit propulsion command signals to the at least one propulsion device in order to reduce speed and alter the direction of the vessel to target values.The invention comprises further a maritime vessel with a corresponding maritime drift control system.
