A horizontal conveyor that is driven by separate loops of chain or a continuous
chain. The chain contacts all roller sprockets, depending on the type and
function of the horizontal conveyor. Either double or single sprockets are
fitted to the horizontal conveyor rollers.
A tube welded to the back side of the VRC column that encloses the lift chain
and tensioner chain.
A device that monitors the lift chain tension. If the lift chain is too tight,
becomes slack, or breaks, the limit switch mounted on the chain tensioner will
trip and remove control power.
The vertical structural members in which the wheelblocks attached to the
carriage travel up and/or down.
Columns shipped in more than one piece must be joined in the field during
installation. Field assembly and welding is required.
A push button which must remain pressed and maintained by the operator
in order to perform a desired operation. If the push button is released, the
desired operation will stop.
Any combination of electrical devices used to control the operation of a VRC.
This normally includes push buttons, relays, limit switches, interlocks, etc.
An enclosure housing various electrical components that control the VRC.
The control voltage is typically provided by the control transformer and is
used to energize the various low voltage electrical devices.
See Vertical Reciprocating Conveyor (VRC).
A static load that is a permanent force, acting on a structure (see Platform).
The floor of the carriage (can be smooth plate, tread plate, or open).
An added measure of safety to prevent uncontrolled descent of the carriage.
Load-defining bar and snap chain across operating end(s) of the carriage to
define the load area on the platform which may minimize load movement.
The diagonal drop bar is hinged at the base and swings down. This is not a
load stop.
The cylinder which transmits lifting force directly to the carriage rather than
through the use of cables, pulley, or chains.
Gear reducer, brake motor and mechanical components that power the chain
that lifts and lowers the carriage for mechanical VRCs. This assembly is
typically mounted at the top of the lift guide columns.
