Jack Stands - PREVOST H3-41 Maintenance Manual

When using the chassis hoisting points to support the vehicle, the tag axle must be unloaded at all
times. To prevent damage to the suspension, always support the drive and front axles using jack
stands when using chassis hoisting points.
CHASSIS HOISTING POINTS
2 hoisting points located aft of the tag axle (Figure3)
2 hoisting points or optional hoisting pads with receptacles located aft of the front axle (Figure4)

JACK STANDS

As a general recommendation, the minimum safe working load (SWL) for any jack stand should be
10 US tons (20 000 lb; 9072 kg). Figure5, Figure6 and Figure7 show general examples of this type of jack
stand.
The vehicle can be supported at the chassis hoisting points (refer to HOISTING AND LIFTING POINTS
diagram). Use a jack stand of 10 US tons (20 000 lb; 9072 kg) capacity at each of the four standard
chassis hoisting points.
WARNING
Hydraulic jacks are intended for lifting only. Do not get under the vehicle while using hydraulic jacks
unless it is properly supported with safety jack stands.
