Pins are used to make the cylinder connections from the pin eyes to the A-frame bearings at the top and the base bearing to the cylinder bases at the bottom. Pivot pins connect the main truck dumper platform to the pivot bearing at the main pivot.  Pin eyes thread into the plunger or final stage of our telescoping hydraulic cylinders. They make the connection to the A-frame bearings which link the cylinder to the Airoflex dumper or tipper. Airoflex Equipment’s spare parts inventory also includes A-frame bearings, which make the connection from the cylinder to the dumper. Airoflex spare parts are durably constructed with quality components for maximum lifespan and performance and undergo quality inspection and rigorous testing before approval for sale. Additionally, OEM spares are designed to retrofit on equipment built in the 1960’s while having the benefit of innovative construction techniques and modern engineering used on contemporary truck dumper and trailer tipper designs.

Routine Inspections

Routine inspection of bearings and shafts for proper lubrication, cracks, scoring, or wear is critical to the safe operation of any equipment.  Cylinders, nuts, bolts, connection points, hoses, piping, alignments, filters, foundations, limit switches and all wear points. These should be examined monthly and changed or repaired if necessary.  When needed, replace these items with certified Airoflex OEM parts at the first sign of wear.

All spare parts are covered under the Airoflex standard warranty.
