Pumps and Function Speeds
The pumps used on the Load King 80-160 Series of cranes are one (1) variable displacement piston
pump, and two (2) gear pump. To produce the proper amount of flow to run the functions at full speed,
the engine with run @1650 RPM with an Allison 4500 Auto Transmission.
The required speed for the pump is very important when testing the unit speeds and checking or handling
maximum loads. Remember also that pump speed and engine speed are not always the same. For
instance, if the truck transmission is equipped with a PTO, the required engine speed to achieve the
desired pump RPM would be approximately 1,650 RPM. It is very important that you know what the ratio
of the PTO is on the unit being serviced.
When involved in troubleshooting a unit that is believed to have slow functions, it is important to know
the pump is receiving the proper RPM and how much flow to expect from the pump. The following charts
will allow you to accurately test the flow of the pump, as well as determine what is the proper speed of
the functions on the unit. Oil temperature below 140 degrees F. may result in slower functions.

The following chart is a list of the speeds you can expect from the Load King Stinger Boom Truck which
are an approximate value. All speeds are one complete cycle. For instance, the swing time is for one
complete 360° rotation.
