Electric Crane Start-up and Task Performance
CAUTION
AVOID MO TOR DAMAGE! The DC electric
motor can overheat. Run for short periods to
avoid overheating. The maximum pump
working period depends on the pressure
required, but working periods should never
exceed 5 minutes followed by cool down to
ambient temperature. See the technical
specifications for pump performance charts
and operating intervals.
Prior to lifting a load:
1 Find the weight of the load.
2 Find the weight of any load handling devices.
3 Add the load and load handling device weights. The sum is the total weight of the load being
lifted.
4 Find the distance from the crane rotation centerline to the load centerline.
5 Find the distance from the crane rotation centerline to the centerline of where the load is to
be moved to.
6 The crane reach required is the larger of items 4 and 5 above.
7 Check crane capacity using this distance and the load weight.
