i4000 Lattice Crane
Instruction Manual
The i4000 « Multifunction indicator» is a computerized system designed to provide the operator
with the necessary information to operate the crane safely, and within the nominal load limits
authorized by the crane manufacturer.
The indicator works by indicating to the operator the load applied to the crane, so that he may
compare this load with the nominal load authorized for each lifting position.
The system’s display unit provides the operator
continuous information regarding the crane’s
current load. It also warns the operator whenever
he approaches or exceeds the maximum load limit.
The system includes sensors installed on the crane
that measure or verify:
•the weight on the hook,
•the boom angle (optional),
•the boom length (optional),
•the position of the A2B block (optional).
When the above options are included, the system uses the information provided by the sensors
to calculate the operational radius, allowing the operator to assess the crane’s current capacity,
and to verify the overload conditions.
A rotation sensor (optional) can also be installed to measure the boom position within 360
degrees and provide the operator with additional information.
The system display is located inside the cabin, close to the operator controls for easy access to the
information. All sensors are connected through a CAN bus network.
The allowed capacity is assessed by the operator. With the measures provided by the i4000 system,
he will be able to identify the allowed load in the manufacturer’s chart.
The actual load is expressed as a percentage of the allowed capacity. This becomes the nominal
load or ‘safe working load’ - % SWL. If this percentage exceeds a predetermined value, the
alarms and safety functions will be activated.
The crane’s parameters and calibration data will be saved in a separate non-volatile memory.
