FUNCTIONAL DESCRIPTION
The EZ Loader is a pneumatic pallet positioner designed to assist the operator when manually loading or unloading
a palletized load. As the load weight increases or decreases the EZ Loader gradually lowers or raises to maintain the
top of the load at a comfortable working height, eliminating operator strain due to bending and stretching.
The EZ Loader is completely variable in capacity. Load support is provided by a Firestone Airstroke Actuator in a
captive air system. Load capacity and height is initially determined by the initial system pressure in the fully raised
position. The initial pressure varies from approximately 10 psi (0.7 Bar) to 60 psi (4.1 Bar). This corresponds to a
collapsed capacity range from approximately 250 lbs (113 kgs) to a maximum of 2700 lbs (1225 kgs). In addition
to the initial system pressure, the EZ Loader has the EZ Adjust capacity adjustment feature which is independent of
the system air pressure. For any initial air pressure setting, the EZ Loader has three (3) collapsed capacity settings;
light, medium and heavy. A capacity change can be made at any time without the need to add or remove air and is
as easy as turning a knob. All additional load above the collapsed capacity is added to the EZ Loader while it is in the
collapsed position. The maximum load capacity is 4000 lbs (1814 kgs).
