Change to Heil Front Loaders Helps Haulers Save Fuel
"Gear pumps have been standard on front loaders for decades," explains Nate Davis, Heil product manager. "Upgrading to a single vane pump is part of Heil's continuous improvement efforts. This new vane pump, coupled with Heil's industry-leading 3 µ filtration system, gives our customers significant advantages over the gear pump still common on other brands of front loaders." Although Heil has used tandem vane pumps in its operate-at-idle system for years, the company still spent a year fully testing the new single vane pump before making it standard on the Half/Pack and Half/Pack Sierra front loaders. The vane pump has fewer leak points, which reduces the potential of hydraulic oil leaks. It also has serviceability advantages. The vane pump's internal cartridge can be replaced without removing the entire pump from the truck. The Heil Half/Pack front loader offers payloads up to 712 kg/m3, a packer cycle time of 22 to 26 seconds and arm cycle times of 18 to 20 seconds. It has the largest front loader hopper in the industry (9,17 m3), to better handle large or over-filled containers. Its exclusive Service Smart clamp-on arms reduce maintenance requirements and make it possible to change arms in a fraction of the time required for bolt-on or welded arms. The Half/Pack is built on Heil's unique interlaced subframe to help the body withstand the stresses of large payloads and rough landfill terrain. Heil's exclusive Shur-Lock hydraulic tailgate lock system enables the vehicle operator to unlock the tailgate, discharge the load and then secure the tailgate, all without leaving the security of the vehicle cab. The system, combined with a 173 cm vertical seal, reduces the chance of leakage from the tailgate while the Half/Pack front loader is on the route. The Half/Pack® Sierra Western U.S. front loader offers all the features and benefits of the Half/Pack front loader, with 13% less weight - thus improving fuel economy even further.

Heil Environmental has made additional improvements to the full line
of Half/Pack® front loaders by upgrading the standard hydraulic pump
offering from a gear pump to a single vane pump. Vane pumps provide a number
of significant benefits, including efficiency increases of up to 20%, lower
system temperatures, greater reliability, improved serviceability, overall
quieter operation, and - most importantly in today's climate of rising fuel
costs - reduced fuel consumption.
