Abstract: A blondin cableway installation, comprises a pair of carrying cables extending between the two ends of the installation; a carriage provided with a lifting tackle and supported movably on the carrying cables; a lifting cable for operating the lifting tackle, extending between the two ends of the installation; an outward haulage cable for conveying the carriage along the pair of carrying cables, said outward haulage cable being connected via tackle to the carriage so as to have a pair of outward haulage sections which extend between the carriage and each end of the installation; and a plurality of cradles arranged along the pair of carrying cables and suspended from them in a stationary manner and designed to support the lifting cable and outward haulage cable, each of the cradles comprising, on each side, a pair of support rollers able to receive by means of gravity, alternately, the outward haulage cable or the lifting cable, and a corresponding pair of retaining rollers able to bias the lifting cable and ha

Abstract: A wire rope reeving support system for a cargo container handling crane having a transport trolley mounted for reciprocation along a horizontal gantry thereof and having a wire rope load hoisting system for the transport trolley wherein a mechanism is provided mid span of said gantry for supporting the wire ropes of at least the load hoisting system and permitting the transport trolley to actuate the rope system to let the trolley pass there by without mechanical interference.

Abstract: An intermediate supporting device for a logging cable for supporting the cable above ground at an intermediate location. The device is arranged to permit a logging carriage to travel past the intermediate location substantially without being obstructed by the device. The device consists of a supporting sheave assembly supported on a transverse line extending between two intermediate spars or spar trees. A first horizontal shaft is swivelly connected to the lower end of the sheave assembly. A normally vertical link bar is pivotally connected at its top end to the first shaft and is pivotally connected at its bottom end to a second horizontal shaft which is parallel to the first shaft. Rigidly secured perpendicularly to the second shaft beneath the supporting sheave assembly is a support body member having spaced transverse vertical flanges with horizontally aligned peripherally grooved pulleys journalled therebetween, the flanges having holes to receive a haulback line engaged in the grooves of the pulleys.

Abstract: A yarder is employed with a running skyline provided with a carriage. The running skyline has an intermediate suspended support consisting of a hanger bar with a shoe pivotally connected to the lower end of the hanger bar by a transverse shaft. The shoe has supporting sheaves and an enclosure rail, with the skyline haulback line supportingly received between the rail and the sheaves. The carriage is open on one side so as to be able to pass the transverse shaft of the intermediate suspended support. The open side of the carriage has a yieldable safety gate which allows the carriage to pass the transverse shaft but which retains the haulback line within the carriage. The lower portion of the carriage has respective sheaves for a slack pulling line and a log suspension line to which logs to be transported are connected. A mainline extends between the yarder and a junction member connected to both the slack pulling line and the log suspension line.
