The drawing produced by PFlow Industries, Inc. which shows the VRC
lift, gates, and enclosures. The drawing may show but does not specify
building details.
Describes moving parts so protected by the parts remoteness from the floor,
platform, walkway, or other working level, or by the parts location with
reference to the frame, foundation, or structure to reduce the foreseeable
risk of accidental contact by persons or objects. The parts remoteness from
foreseeable, regular, or frequent presence of public or employed personnel
may constitute guarding by location in reasonable circumstances. (See ASME
B20.1 standard)
Guide angles are attached to the guide column to help capture and contain the
guide wheels in the columns and guide the carriage.
The structural members connected to the carriage that guide the carriage
travel up and down.
Header refers to the horizontal structure spanning the width of the carriage or
gate. The carriage header defines the load height on straddle units.
The user interface in the control system that provides graphic control of the
VRC. The HMI communicates with the programmable logic controller (PLC).
VRC mechanical shaft of the mechanical drivebase which penetrates the gear
motor rather than coupling to the gear motor. This minimizes wear points.
A device which converts fluid power into linear force and motion. The
hydraulic cylinder usually consists of a movable element such as a piston and
piston rod, plunger or ram, operating within a cylindrical bore.
Refers to motor, pump, and reservoir assembly. The reservoir is shipped with
oil. Most hydraulic power units come with the control panel attached and
pre-wired to the hydraulic pump.
The main voltage being supplied for operation of the equipment.
An electro-mechanical locking system used on the gates or access doors of a
VRC. The system prevents the VRC operation unless all such gates or access
doors are closed. The system also prevents the opening of any such gate or
access door unless the VRC carriage is present at that particular landing
or opening.
A floor level or levels between the uppermost and bottommost operating floor.
An electrical control box used to join, centralize, and distribute wiring from
different locations.
A keyed push button station that prevents unauthorized use of the VRC.
A curb on the outermost edge of the inoperable sides of the carriage deck
which is designed to contain product and is a minimum of 4" (102mm) high.
Lift components shipped in two or more pieces. Typically field welding is
required (e.g., KD carriage, KD headers, KD uprights, KD gates, etc.).
