摘要： A trolley 100 for a rail 10 is described. The trolley 100 comprises a frame 110, a set S of wheels 120, including a first wheel 120A and a second wheel 120B, rotatably coupled to the frame 110 and an attachment member 130, coupled to the frame 110, for suspension of a load W therefrom, in use. The first wheel 120A is rotatable in a first plane P1 about a first axis A1 and the second wheel 120B is rotatable in a second plane P2 about a second axis A2. The first plane P1 and the second plane P2 define a line L. The trolley 100 is arrangeable in a first configuration, wherein the attachment member 130 is arranged at a first angular displacement D1 about the line L. The trolley 100 is arrangeable in a second configuration, wherein the attachment member 130 is arranged at a second angular displacement D2 about the line L, wherein the first angular displacement D1 and the second angular displacement D2 are different. A rail assembly 1, including the trolley 100 and the rail 10, is also described.

摘要： A switch is described. The switch is for interconnecting a first rail providing a first portion of a running surface for a wheel and a second rail providing a second portion of the running surface wherein a first end of the first rail and an opposed second end of the second rail are axially mutually spaced apart by a first spacing. The switch comprises a set of rail segments including a first rail segment, having a first end, a second end and a first length therebetween correlating with the first spacing. The switch is arrangeable in a first configuration, wherein the first rail segment is arranged to interconnect the first rail and the second rail, thereby providing an interconnecting portion of the running surface between the first portion and the second portion. The switch is arrangeable in a second configuration, wherein the first rail segment is transversely spaced apart from the first rail and/or the second rail. The switch is arranged to move from the first configuration to the second configuration by a first transverse movement of the first rail segment.

摘要： A stop for stopping a trolley on a rail is described. The trolley comprises a set of wheels, including a first wheel and the rail provides, at least in part, a running surface, including a first portion and a second portion thereof, for the first wheel. The stop comprises an actuator providing a third portion of the running surface between the first portion and the second portion and an arm, coupled to the actuator. The stop is arrangeable in a first configuration, wherein the arm is arranged to block the trolley therepast. The stop is arrangeable in a second configuration, wherein the arm is arranged to allow the trolley therepast. The stop is arranged to move from the first configuration to the second configuration by actuation of the actuator, preferably by a movement of the actuator in a direction transverse to the third portion of the running surface.
