Telescoping rigid frame/scissor conveyors. Such conveyors are formed of a plurality of telescoping frame segments which may be positioned at any number of desired nested/unnested configurations. The frame segments bear a lazy tong or scissors conveyor structure which assures uniform roller spacing, and rollers positioned at one height along the conveyor rather than at different heights for each frame segment. Counterintuitively, the increased structural complexity is more than outweighed by the benefits resulting from the uniformly positioned rollers of a uniform height, which are thus adapted to convey articles in a reliable and jam-free fashion unlike previous expandable rigid frame conveyors. Conveyors according to the present invention may contain automatic locks to prevent overextension, powered rollers and motive devices for automatic and reliable extension and retraction.

Expandable powered conveyors featuring a number of roller power motors located externally of the rollers. The conveyors include a pair of lazy tong trusses which may be supplemented, as desired, by telescoping rigid frames, leg structures or other structures. The motors are mounted between the trusses so that their drive pulleys are located substantially coaxial to the middle connection points of the scissor bars in the trusses and thus maintain a substantially constant distance from rollers connected to those scissor bars. Drive belts connect the motor drive pulleys to power such rollers. The conveyors also include a number of transfer pulleys which are also mounted substantially coaxial to corresponding middle connection points of the trusses. A single motor may thus power one or more rollers directly, and other rollers indirectly via motor drive belts and transfer drive belts. Use of a number of motors allows grouping of rollers into zones with the same advantages enjoyed in more expensive internally powered roller conveyors, but with greater reliability, ease of maintenance and savings and expense.

Power modules for expandable conveyors. The power modules contain motor driven rollers whose operation may be speed, direction and otherwise controlled as desired. The module connects to the end of an expandable conveyor, such as a conventional scissors conveyor, to allow repositioning, expansion and contraction of the conveyor with minimum risk of overexertion, strain and injury. Rollers may be positioned along the top surface of the power module as an extension of the conveyor for conveying items to ultimate destination. Gripping surfaces may be provided which act in combination with swivel mounted wheels to allow efficient and effective steering of the power module and the conveyor. The gripping surfaces may be located conveniently in the vicinity of a control panel for controlling actuation of the motor and the drive wheels. The power module accordingly allows efficient and effective repositioning, expansion and contraction of expandable roller conveyors that help meet increasing ergonomic and worker welfare considerations being entertained and implemented by enlightened employers.

Telescoping rigid frame/scissor conveyors with suspension structures to accommodate less than totally flat surfaces, and for easy and ergonomic repositioning. Such conveyors are formed of a plurality of telescoping frame segments which may be positioned at any number of desired nested/unnested configurations. The frame segments bear a lazy tong or scissors conveyor structure which assures uniform roller spacing, and rollers positioned at one height along the conveyor rather than at different heights for each frame segment. The conveyors are adapted to bear greater weight than conventional lazy tongs conveyors, but contain suspension systems in order to conform to irregularities in factory and warehouse floors and slabs and for easy movement. The suspension systems may include motorized drive units, swivel mounted roller units, jacking roller units and more conventional rigid legs that contain springs or other suspension members to distribute the loads of and borne by the conveyors evenly and efficiently, and to allow the conveyors to positioned, expanded and retracted easily and efficiently.
