Stability - Vanguard CPW 125-4-S Series Operation And Maintenance Manual

Report any needed repairs that were noted during operation.

Stability

A well trained operator that follows the instructions in the Operation and Maintenance Manual has the greatest impact on
stability. Operator training provides a person with the following abilities: observation of working and environmental
conditions, feel for the machine, identification of potential hazards, and operating the machine safely by making appropriate
decisions.
When you work on side hills and when you work on slopes, consider the following important points:
Speed of travel - At higher speeds, forces of inertia tend to make the machine less stable.
Roughness of terrain or surface - The machine may be less stable with uneven terrain.
Direction of travel - Avoid operating the machine across the slope. When possible, operate the machine up the slopes and
operate the machine down the slopes. Place the heaviest end of the machine uphill when you are working on an incline.
Mounted equipment - Balance of the machine may be impeded by the following components: equipment that is mounted
on the machine, machine configuration, weights, and counterweights.
Nature of surface - Ground that has been newly filled with earth may collapse from the weight of the machine.
Surface material - Rocks and moisture of the surface material may drastically affect the machine's traction and machine's
stability. Rocky surfaces may promote side slipping of the machine.
Slippage due to excessive loads - This may cause downhill tracks to dig into the ground, which will increase the angle of
the machine.
Height of the working load of the machine - When the working loads are in higher positions, the stability of the machine
is reduced.
Operated equipment - Be aware of performance features of the equipment in operation and the effects on machine stability.
Operating techniques - Keep all attachments or pulled loads low to the ground for optimum stability.
Machine systems have limitations on slopes - Slopes can affect the proper function and operation of the various machine
systems. These machine systems are needed for machine control on slopes.
Note: Safe operation on steep slopes may require special machine maintenance. Excellent skill of the operator and proper
equipment for specific applications are also required. Consult the Operation and Maintenance Manual sections for the proper
fluid level requirements and intended machine use.
Note: Refer to the carrier's operation and maintenance manual for further specific requirements for safe operation on steep
slopes.
Additional counterweight added to the vehicle may be required to ensure the carrier vehicle is stable, contact the carrier
vehicle dealer for more information.
Load Capacities
Maintain control of the machine. Do not overload the machine beyond the machine capacity. Ensure that the correct load
capacity indication film is referenced. The supported load must be within the capabilities of the machine to ensure that the
carrier vehicle does not become unstable. Load capacity decreases as the load is moved further from the machine.
Wire rope limitations, soil conditions, and slope of terrain reduce actual capacity. All lifts must be made with the load line
vertical, and the boom centerline directed toward the load.
To prevent cable from slipping off the drum, a minimum of five full-wraps of cable must remain on the winch drum at
maximum working extension of the hook or boom
The machine may tip and personal injury may occur if the maximum load capacities are exceeded. Load capacities assume
that the machine is stationary on a level concrete surface. Lift capabilities/capacities will decrease on slopes or soft ground.
