GETTING STARTED PLEASE READ THIS MANUAL CAREFULLY BEFORE USING THE EZ LOADER. The safety of all persons installing, using or servicing the EZ Loader is of utmost importance to Bishamon. The EZ Loader is capable of supporting heavy loads and is capable of causing SEVERE PERSONAL INJURY if used improperly or if certain safety precautions are not taken. When properly used and maintained, the EZ Loader will provide many years of safe, trouble free service.
10. When removing a loaded pallet, ALWAYS raise the load until the bottom of the pallet clears the top of the EZ Loader before backing up. ALWAYS stay well clear of the load while it is being removed from the EZ Loader. SEVERE PERSONAL INJURY and PROPERTY DAMAGE could result. 11. ALWAYS ensure all safety warning labels are in place and legible. If not, remove the EZ Loader from service and replace the required labels. Refer to Figure 1 for label descriptions and locations. 12.
SPECIFICATIONS AND SPECIFICATION DRAWING Figure 2 Specification Drawing 3
RECOMMENDED FLOOR AREA & CEILING HEIGHT Figure 3 Recommended Floor Area & Ceiling Height The EZ Loader’s recommended floor area, shown in Figure 3, identifies the “Danger Zone” and the “Operating Zone”. The Danger Zone is the area inside the base frame and under the platform structure. The recommended Operating Zone is a distance of 39 inches (1 meter) extending beyond the danger zone on all sides. The EZ Loader also requires a minimum ceiling height to operate within.
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.
SCISSOR BLOCKING INSTRUCTIONS To Engage The Maintenance Bars 1. 2. 3. Remove all load from the platform and allow the EZ Loader to extend to its fully raised position. As detailed in Figure 5, lift each maintenance bar until the bottom of the bar contacts the scissor axle. Ensure both maintenance bars completely engage the axle. Turn the EZ Adjust knob (identified in Figure 6), to the charge/discharge position and slowly open the purge valve to release the air from the system.
INSTALLATION Installation of the EZ Loader is a simple process; however, certain precautions must be taken to ensure years of trouble free service. The EZ Loader requires clean, dry, compressed air to operate properly. A filter and regulator with a pressure gauge should be installed on an air line in the installation area before initially charging the system for use. Before you begin, locate and identify the pneumatic components detailed in Figure 6.
Position also corresponds to the lightest load setting. For any air pressure setting, this position will allow the EZ Loader to completely collapse with the least amount of load. Medium Weight Position - is the medium load capacity setting. At this setting, the EZ Loader will collapse slower and will require more load to completely compress the platform to its collapsed position. Heavy Weight Position - is the high load capacity setting.
Figure 9 Handling the EZ Loader QUICK SET-UP The EZ Loader is complete variable in capacity and very easy to set up. Complete the installation instructions detailed on page 8 Turn the EZ Adjust knob to the Light Weight Position and pressurize the EZ Loader to 60 psi (4.1 bar) in the raised position. Place all or any portion of the load on the EZ Loader, then open the purge valve to release air and set the top of the load at the desired working height. Close the purge valve finger tight.
A diagram of the rotator ring height as it relates to the load weight for the EZ Loader is shown below in Figure 10. Figure 10 illustrates the change in performance due to both changes in initial pressure and changes in the EZ Adjust knob position. Figure 10 EZ Loader Height vs. Load Diagram For most applications, the EZ Loader should be completely collapsed at approximately 75 percent of the total load (load + pallet weight).
Note: The ideal initial pressure setting depends on many factors; including load density, load height, load variability and operator height. Should the desired response require a slightly stiffer spring setting, simply remove the load, turn the EZ Adjust knob to the Light Weight Position and add air. Typically, a 5 psi (0.3 bar) change in initial pressure is adequate. Likewise, if a slightly softer spring setting is desired, simple remove air.
EZ Adjust Knob Operation 1. The EZ Adjust knob provides for quick and easy capacity changes without the need to add or remove air. The amount of capacity change for each knob position is relative to the initial system pressure. However, each knob position changes the collapsed capacity by approximately 40%. 2. The position of the EZ Adjust knob can be changed at any time during the loading or unloading cycle.
WARNING NEVER go under the platform until the load is removed and the scissor mechanism is blocked. SEVERE PERSONAL INJURY could result. WARNING Before servicing any component in the EZ Loader’s pneumatic system, ALWAYS open the purge valve and discharge all air pressure. SEVERE PERSONAL INJURY could result. Monthly inspection should consist of the following: 1. Inspect the snap rings at all rollers and linkage assemblies. If not in place and/or secure, replace or repair at once. 2.
Figure 12 EZ Loader Pneumatic Schematic REPLACEMENT PARTS Bishamon has carefully selected the components used in the manufacture of the EZ Loader. In the event replacement parts are required, ALWAYS use genuine EZ Loader components provided by Bishamon. These parts can be obtained from your Bishamon DEALER or by contacting Bishamon Industries Corp. For detailed exploded views and parts lists contact your dealer, Bishamon Industries Corporation or visit www. bishamon.com.
Chart 2 EZ Loader Performance Notes: 1. The above chart is for reference only to illustrate the capacity variability of the EZ Loader. Other initial pressures may be better suited for a specific loading/unloading application. 2. There are multiple EZ Loader settings for most pallet weights. For example, consider a total pallet load of 1650 lbs.
