Proper Operational Procedures Improves Dumper Performance

Depending on the complexity of the equipment and controls, there are a few options for production personnel to learn how to operate the equipment. The manual explains the operation of the equipment and its components. The customer can visit Apache for training and testing or contract with Mepaco Field Services for on-site training.

In one example, the production staff did not understand how to operate the HD3000 Dumper, causing the carriage to bind-up where cylinders weren't lifting in tandem. The issue was caused by incorrect operation.

Due to the operational configuration of the hydraulic cylinders, the HD300 dumper must be fully cycled (complete cylinder extension and retraction) each time it is used. The production staff was not fully retracting the dumper leaving the carriage 12 - 18" off the ground. This allowed the cylinders to start up unevenly and compounded if the staff did not fully extend the dumper. This caused the dumper carriage to misalign and bind against the dumper frame.

Once the carriage binds against the frame the only way to safely correct the situation is to lock out the hydraulic power unit, disconnect the hydraulic line from the overextended cylinder and allow the carriage to drift down until it is re-timed. Once the cylinders are re-timed the power unit can be operated to bring the carriage to the fully down position. Air will need to be bled from the cylinder that had the hydraulic lines removed.

Please call Joe Hertel, Field Services Manager, at 920-219-2286 if you have any questions about the operation of Mepaco equipment or if a training visit is necessary for new personnel.
