Idler roller

A conveyor includes an endless belt, a boot end supporting a portion of the endless belt, a support structure, and a bridge. The endless belt includes a first run and a second run, and the first run extends along a conveyor axis. The support structure includes an end spaced apart from the boot end, a plurality of frames, and a plurality of idler rolls. The frames are spaced apart from one another and aligned with one another in a direction parallel to the conveyor axis. The idler rolls support another portion of the endless belt. The bridge extends between the boot end and the end of the support structure. The bridge is movable in a direction parallel to the conveyor axis relative to at least one of the boot end and the support structure.

Conveyor bridge

A tensioning mechanism for a conveyor system includes a first end including a drive unit, an anchor structure, a continuous belt extending at least partially between the drive unit and the anchor structure, a first carriage, and a second carriage. The first carriage is coupled to the drive unit and supports a portion of the belt. The first carriage is supported for movement relative to the drive unit to adjust a tension in the belt, and the first carriage is movable between the drive unit and an intermediate position. The second carriage is releasably secured to the anchor structure and supports another portion of the belt. The second carriage is supported for movement relative to the anchor structure between a first position and a second position. A distance between the first end and the second carriage defining a take-up length, and movement of the second carriage changes the take-up length.

Take-up mechanism for conveyor system

A tensioning mechanism for a conveyor system includes a support structure, a first carriage, a second carriage, and a brake mechanism. The first carriage is positioned proximate a first end of the support structure and is supported for movement relative to the support structure. The first carriage includes first rolls for receiving the belt such that movement of the first carriage modifies a tension in the belt. The second carriage is supported for movement relative to the support structure and includes second rolls and at least one return pulley. The second rolls are configured to support a portion of the belt extending between the first carriage and the second carriage. The brake mechanism is positioned proximate a second end of the support structure and includes a brake pulley and a brake selectively retarding rotation of the brake pulley. The brake pulley supports a portion of the belt extending between the brake mechanism and the return pulley.

Brake system for conveyor take-up mechanism

Systems, methods, and computer-readable medium containing instructions for operating a conveyor. One method includes receiving, by a controller, a signal from each of a plurality of substations. Each of the plurality of substations provides power to a motor drive unit driving a conveyor belt of the conveyor. The signal received by the controller indicates whether an isolation switch associated with each substation has been manually operated. The method also includes, when the signal received from one of the plurality of substations indicates that the isolation switch associated with the one of the plurality of substations has been manually operated, transmitting, by the controller, a signal to each of the plurality of substations, the signal instructing each of the plurality of substations to isolate the motor drive unit from a power source.

Drive isolation systems and methods for conveyors

A winch drum tension isolation system includes a winch drum including an outwardly extending flange, the flange including a plurality of holes spaced along the flange. The winch drum tension isolation system also includes a locking mechanism positioned proximate the winch drum and including a locking member engageable with the flange. The locking member is movable between a first position, in which the locking member is received in one of the plurality of holes to prevent rotation of the winch drum, and a second position, in which the locking member is spaced apart from the flange to permit rotation of the winch drum.

Winch drum tension isolation system

A storage platform is incorporated into the main conveyor. The machine is movable, and incorporates space for the storage of main conveyor structure. The machine also includes a mechanism for raising the top of the endless belt, and for permitting the lower or return portion of the endless belt to pass through the mobile machine.
