Drive chains on the F series mechanical VRC, through a series of a shaft and
sprockets allow the carriage to be raised and lowered.
The action of a lift carriage slowly dropping, usually due to slight internal
leaks in a hydraulic system or mechanical slippage of a motor brake.
An electrically powered bi-panel vertical acting gate.
Refers to usable space for the materials load on the carriage, not the overall
dimensions which includes space allowed for carriage side guards and
snap chains.
Electrical cables consist of at least two conductors contained within a
protective outer cover.
Structure surrounding a VRC to prevent outside interference with its normal
operation and to safeguard personnel. Typically 8' (2438mm) high panels
composed of expanded metal or other materials that will prevent a 2" (51mm)
diameter ball from passing through (ASME B20.1 requirement).
Abrasion-resistant, two-part industrial-strength protective coating system
applied over sandblasted and primed steel or direct to metal. The epoxy
coating is ideal for outdoor, chemical, or caustic wash-down environments or
applications where standard alkyd enamel is viewed as insufficient.
An electrically powered single panel vertical acting gate.
A sheet of metal uniformly slit and stretched, forming diamond-shaped
openings in the metal sheet. Expanded metal is a one piece construction
that will not unravel under normal circumstances and will hold its shape.
Expanded metal comes in a standard (raised) or flattened diamond pattern in a
variety of gauges, opening sizes, materials and sheet sizes.
Electrical devices (e.g., control panels, motors, limit switches) that are
designed to operate safely in a specific location or area where potentially
explosive environments can or do exist.
The distance from one operating floor level to the adjacent operating floor
level (see Vertical travel).
Structure surrounding the full height of a VRC to prevent outside interference
with its normal operation and to safeguard personnel. Typically panels
composed of expanded metal or other materials that will prevent a 2" (51mm)
diameter ball from passing through (ASME B20.1 requirement).
A device that opens and closes manually or automatically to allow access
to the carriage for loading and unloading. The gate is normally a swing,
sliding, or vertical acting device constructed of similar expanded metal as the
enclosure (see specific gate type).
