Why APPI: Tower cranes provide an efficient material handling solution for high-lift applications on long duration projects such as new construction and major renovation projects. The high cost associated with renting and setting up a tower crane, or a mobile crane when building heights would allow their use, makes them prohibitively expensive for smaller projects.
Crystal Services, a leading industrial rigging company in Alberta, Canada, turned to APPI while researching for an alternative to the high cost of using a tower crane for high-lift applications. They required a high lift hoist system that could be transported to the top of a building freight elevators that would not sacrifice capacity or speed to ensure their projects came in on time and budget.
Working closely with Crystal Services Operations Manager, Cam Moody, it was determined one of our Columbia HL7000-4A17-L-04 AC electric hoists would meet their performance requirements. By adding one of our proprietary AutoAdvance Line Spoolers – installed in an inverted position – proper line spooling, even with minimal fleet angle, was ensured.
Cam indicated that this high lift hoist system has worked so well as an alternative to using a tower crane they are expanding their business and will be adding additional systems in the near future.
