A mining shovel (10) is provided with an automatic lubricant system controlled by movement of a portion for the mining shovel (10). The automatic lubrication system includes an actuator (51, 151, 251, 351) and a lubrication supply subsystem (53, 153, 253, 353). The lubrication supply subsystem (53, 153, 253, 353) delivers lubricant to a selected site in response to movement of the actuator (51, 151, 251, 351).

Dipper door actuated lube pumping system

An apparatus for drying a moving web includes an elongate support frame, disposed transverse the web, and a number of heater modules releasably attached thereto. The heater modules each include a housing and an inner panel assembly releasably captured therein. An openable cover, in the housing, provides for ready insertion or removal of the inner panel assembly, which rests on two mutually perpendicular support members and is clamped against one of them by the closed cover. A number of heating elements are operatively supported on the inner panel assembly by means which include a locking member displaceable between a first position, whereat all of the heater elements are locked in position, and a second position, whereat the heater elements may be removed.

Infra-red lamp module

A dockboard having movable cross-traffic legs associated therewith, and a latch mechanism which automatically engages and holds the cross-traffic legs in a retracted position when the dockboard is being actively utilized for loading or unloading a truck. The latch mechanism is automatically unlatched following removal of the truck bed from beneath the ramp so that the legs are returned to their active position for supporting the ramp flush with the dock.

Leg latch for in-pit dock levelers

A dock leveler having a ramp structure hingedly mounted on a support structure for swinging movement about a substantially horizontal hinge axis. A lifting mechanism coacts between the structures for normally urging the ramp structure to swing upwardly about the axis. A releasable holding means coacts between the structures for normally preventing upward swinging movement of the ramp structure. The holding means including a one-way latch device for permitting downward swinging movement of the ramp structure while restricting upward movement thereof. The holding means includes torsion spring means operatively coacting between the latch device and one of the structures for permitting upward swinging movement of the ramp structure through a limited angular extent even when the latch device is in a latched position in response to imposition of an external lifting force on the ramp structure.
