Operating Instructions
Load Management System
The Load Management System (LMS) is a safety
system designed to monitor the telehandlers
stability condition during the loading/unloading
cycle when the machine has stopped travel
(Figure 1). The LMS is integral with the machine
electronics and boom movement commands. The
LMS restricts further de-stabilizing movements
when the rated capacity of the machine is reached.
This system continuously monitors the actual
load, load position, configuration and geometry
of the telehandler. The graphical interface shows
the actual load on the attachment, rated capacity
based on boom position and a load chart showing
the position of the load reference point of the
load being handled. When the telehandler rated
capacity is reached, the following movements are
disabled: Boom raise/lower, boom extend and
attachment tilt forward.
The LMS is designed to warn when the rated
capacity is being reached and restrict de-
stabilizing movements of the load only during the
loading/unloading cycle, it does not address the
risks associated with pick and carry operations.
The LMS is an electronic system including several
sensing components and may be subject to
component failure. These electronic components
are constantly monitored by the LMS, so the
system is able to notify the operator when a fault
occurs; alarms and warnings describing the type
of fault are communicated to the operator via the
display unit.
The risks associated with the following hazards
are not controlled by the LMS:
•
Overtuning due to set up outside the operating
limits specified on the load chart.
•
Incorrect attachment selection.
•
Pick and carry operations
Functionality
The LMS is a system designed to assist the
operator during the loading/unloading cycle.
However, the LMS is not intended as a substitute
for the guidelines esablished in this manual
relating to the proper use of the machine. When
the telehandler is first started, boom operations
are disabled and can only be enabled by selecting
an attachment from the LMS's display unit.
The operator is responsible for the selection
of the attachment from the display unit.
The operator must ensure the attachment
description shown on the LMS's display
screen matches the attachment fitted on the
telehandler.
