Adjust Dock Leveler and Vehicle Restraint Interlock
Dock Leveler & Vehicle Restraint Interlock
Options
There are two options to interlock the dock leveler
and vehicle restraint*:
• Restraint Engage before Leveler Operate (RELO)
Interlock: Dock leveler can be interlocked with
a vehicle restraint to prevent the leveler from
operating until the restraint has engaged the
transport RIG (Rear Impact Guard) when the
OPERATION MODE is NORMAL and has NOT
been switched to BYPASS MODE.
• Leveler Stored before Restraint Release (LSRR)
Interlock: Vehicle restraint is interlocked with
the dock leveler so that the restraint cannot be
operated until the leveler is stored in the cross
traffic position (lip fully folded, inside the keepers,
and the platform level with the dock floor).
Interlocking is overridden when the OPERATION
MODE is in BYPASS. This allows the independent
operation of the leveler (the restraint cannot be
operated in BYPASS MODE).
Pressing the restraint RELEASE button when in
BYPASS mode will return the leveler to NORMAL
operating mode.
Special interlocking options are available upon
request. Call Systems, LLC to discuss interlock
options to meet your specific needs.
*Dock levelers equipped with Auto-Return-To-Dock
have limited interlocking options. Auto-Return-
To-Dock feature is not available for dock levelers
equipped with combination dock leveler/vehicle
restraint control panels.
ADJUSTMENTS
It is recommended and good safety practice to use
an additional means to support the dock platform
and lip anytime when physically working in front of
or under the dock leveler. This additional means
may include, but is not limited to a boom truck, fork
truck, stabilizing bar or equivalent.
Always post safety warnings and barricade the
work area at dock level and ground level to prevent
unauthorized use of the dock leveler before
maintenance is complete.
A hard hat or other applicable head protection
should always be worn when working under or
around a dock leveler.
Always stand clear of platform lip when working in
front of the dock leveler.
