WHY APPI:
Local PUD engineers rejected a hoist design for lifting 15,000-pound pumps. As a result, Billy Ball, the Sales Manager for Lafollette Mining Supply, began searching for a reliable solution provider. He told us he chose APPI because of our strong customer reviews and our wide range of successful applications.
Lafollette Mining Supply clearly outlined their needs. First, they wanted a barge-mounted hoist system to lift heavy pumps from depths up to 125 feet. Additionally, the system needed to work in a marine setting. Furthermore, it had to fit within their existing crane frame’s limited headroom. Finally, the design needed to move pumps fore and aft during maintenance.
After detailed discussions, Lafollette Mining Supply and APPI together crafted an effective solution. We agreed on a system using two Columbia HL12000 Hoists paired with two motorized 15-ton hammerhead trolleys. This setup delivers up to 30,000 pounds of line pull to free pumps from depth. Moreover, it keeps pumps at a steady height while the trolley moves across the deck.
This jointly developed pump hoist system offers several key benefits:
- The high-efficiency planetary reductions create a compact design
- The 5 HP TEFC UL-listed brake motors ensure reliable operation
- Synchronized controls allow for precise handling of heavy pumps
Billy happily reported that PUD engineers quickly approved our solution. Subsequently, the team has been impressed with the system’s performance in daily operations.
