Loading & Use Instructions:
This steel dumping hopper is suitable for use indoors and outdoors and in most industrial and commercial
settings. However, the hopper should be stored indoors to prevent rusting and corrosion.
Do not exceed the maximum rated load of your hopper (see p. 2 and label 287 in “Label placement diagram” on p.
7) or heap material above the sides of the hopper. Personal injury or permanent damage to the hopper could
result from overloading.
Move the hopper to the desired dump site and orient the hopper so that the chute is positioned appropriately. Lift
the end of the hopper by the handles. As you raise the end of the hopper, the rocker plates contact the ground.
The front of the hopper pivots about the rocker plates until the front of the chute rests on the ground. Clean out
any material that remains in the hopper.
Inspections & Maintenance:
If inspection reveals problems, restore the hopper to normal operating condition BEFORE using it again.
DO NOT use a structurally damaged hopper. Structural damage includes, but is not limited to, cracked welds,
warping or deformation of one or both of the rocker plates, and damaged casters.
Inspections:
Inspect the following components at least once per month and replace any component that is excessively worn or
no longer operates normally. If a component cannot be replaced, remove the hopper from service:
1.) Hopper chute – examine the hopper for damage, deformation, and corroded or excessively rusted
regions;
2.) Rocker plates – look for excessive wear, warping, or other significant damage. The rocker plates
should be symmetrical to allow the hopper to pivot evenly and smoothly.
3.) Casters – check for looseness, excessive wear, or damage to the casters, caster bearings,
mounting brackets on the underside of the hopper, and retaining hardware.
4.) Labels – all labels must be firmly affixed in the locations shown on p. 7.
Maintenance:
The end-user should implement a maintenance program to preserve the hopper in normal operating condition for
as long as possible. The following steps should be applied to complement established maintenance programs.
The end-user is responsible for selecting and training employees to work on the hopper. ONLY
trained, authorized maintenance personnel or contractors should inspect, maintain, or repair the hopper.
Step 1: Tag the hopper, “Out of Service.”
Step 2: Remove any dirt or other matter from all surfaces.
Step 3: Conduct an inspection as described above. If deformity, corrosion, rusting, or excessive wear of structural
members is found, DO NOT use the product.
Step 4: Perform all other necessary adjustments, replacements and/or repairs, but DO NOT modify the hopper.
The reader should understand the significant difference between necessary adjustments and
repairs, and modifications.
An “adjustment” is a simple correction that restores the hopper to normal operating condition, such as
tightening loose fasteners, or removing dirt or other debris from the surface. “Repair” means removing worn parts
and installing new, replacement parts.
DO NOT use the hopper if adjustments and/or repairs are incomplete! Return it to service ONLY after
finishing all necessary repairs and adjustments.
A “modification” is a change that alters the hopper from normal operating condition, like bending the structural
members or removing a part or several parts. NEVER modify the hopper. If the hopper is modified, the limited
warranty is automatically void. Additionally, modification might make the hopper unsafe to use.
Step 5: Make a dated record of all repairs, adjustments and/or replacements performed.
