JLG 1644, 1732 Telehandlers
The 1644 and 1732 telehandlers have lift capacities of 15,600 and 16,750 pounds, respectively. SmartLoad Technology includes attachment recognition, which allows a telehandler to identify an attachment and display the appropriate load chart to the operator. A load management information system (LMIS) graphically depicts the location of the load within the load chart, provides the operator with an indication of compliance, and prevents the operator from violating the boundaries of the chart. A load stability indicator (LSI) works in conjunction with the LMIS to limit operation when a load becomes noncompliant.
The precision gravity lowering system uses gravity to lower the boom, providing the operator with more precise control.
