Me thinks you need to provide more information first.

1. You did not mentioned what type of Crown units you bought, the voltage of the units and what mast , etc. the untis were equipped with.. This needs to be clarified

2. What speeds are you talking about - lifting speeds, travel speeds, reach speeds or what? Some folks that have replied are assuming travel speeds. This also needs to be clarified.

3. Were the units equipped with cold or freezer storage protection - was the correct fluid installed for the operating temperation & time in the cold enviroment. Oil viscosity can have an effect on travel, lift, reach, etc. speeds. Don't assume it was - remember this is 2007 & people to build the units. This should be verified.

4. What is the actual temp. of the cold/freezer operating enviroment - not the freezer rating.

Once this information is definedd then more accurate rresponses can be provided.
