A trolley wheel assembly for use with an overhead conveyor system. The trolley wheel assembly includes a roller comprising a solid generally cylindrical body with a blind bore opening in the outboard face of the roller; a shaft positioned at one end in the blind bore and having a free end projecting out of the bore for connection to a trolley hanger; a bearing positioned in the blind bore and including an inner race press fit on the shaft and an outer race press fit in the blind bore; and a meta...

A steerable trolley, typically a shopping trolley, comprises two or more pivotable wheels and the steering mechanism comprising communication elements between a driving wheel and corresponding driven wheel, the communication elements being operable such that pivotal movement of the driving wheel about a substantially vertical axis acts to produce a pivotal movement of the corresponding driven wheel, wherein when the driving wheel is a rear wheel the driven wheel is a front wheel and vice versa. ...

The specification discloses a trolley wheel assembly useful in conveyor applications especially in the food processing industry. The assembly includes a plastic wheel, metallic outer and inner races positioned with respect to the wheel and antifriction means such as ball bearings between the races. The outer races include noncircular, circumferential surfaces, preferably flat or rectilinear edges on radial flanges of the annular, contoured rings forming the outer races, engaging corresponding no...

A span trolley detachably connectable to a line suspended between first and second poles to draw an end of a cord from the first pole to the second pole. Two guide wheels and a drive wheel, secured to a chassis, are resiliently urged into engagement with the line extending between the poles. The chassis is moved along the line by a reversible variable speed electric motor to draw a cord having an end connected to the chassis along the line. The resiliently mounted guide wheels are adapted to mov...

The invention provides a table comprising a first and a second set of legs and a table top; the table top being optionally supportable by either the first or the second set of legs and wherein the table top is pivotally attached to the second set of legs whereby, when supported by the second set of legs, the table top may be pivotable from a generally horizontal position to a generally vertical position. It is preferred that the first set of legs is so mounted to the table top to demountably pro...

A trolley includes a track having first and second ends. A pivot is located between the first and second ends of the track so that movement of the first end of the track causes opposite movement of the second end of the track. A counterweight is located near the first end of the track so as to apply downward force. A trolley is movable along a portion of the track located between the pivot and the second end of the track. The trolley has a handle or carriage for a user. The combined weight of th...

Trolley wheels and guide rollers for a monorail trolley system and a method for reducing debris originating from trolley wheels and guide rollers particularly in the production environment of producing iron-sensitive photographic materials.

A wheeled trolley comprising a base chassis which includes a load support platform and a set of ground-contacting wheel elements which may be swivel castors, and an upright support structure fixed to and projecting upwardly from a rear portion of the base chassis, and surmounted by a push-handle assembly. In one aspect an upwardly open supplementary luggage receptacle is mounted on the rear side of the upright structure to permit the receptacle to be made substantially larger than hitherto witho...

A lifting trolley having a main frame supported on ground engaging wheels, a handle pivotally connected to the main frame and a lifting sub-frame which is vertically movable with respect to the main frame is disclosed. The sub-frame has a pair of spaced apart arms, each of which include retractable engagement means in the form of pivoting catch members that are adapted to secure a load, such as a stack of crates, to the sub-frame. Linkage means, such as a pulley and cable assembly between the ha...

A trolley bracket comprises at least one element (3', 3") which comprises a pivot (8) for receiving a wheel (2) movable along a guide (1) and rotatable by way of a bearing (5), and a member (9) hanging down from the pivot and having an element (10) for connecting the element to an object to be carried by the bracket. The pivot (8) and the hanging member (9) are formed as an integral piece from plastic, e.g. injection-moulded, fibre-reinforced polyamide.
