クレーンキャリアー社は、ISE社とともに、大部分のトラックシャシーでフレームレールの間に簡単に取り付けられることができる自己充足的なハイブリッドドライブアセンブリを使っていゴミ収集車（HEV）を提案しました。それは、従来のマニュアルまたは自動変速装置アセンブリをクレーンキャリアーLET2シャシーに戻します。提案されたHEVシステムは、重い60フィートのトレーラー式バスアプリケーションで通過市場のためにISEによってすでに開発された部品を使います。HEVは、彼らの通常の活動の間、ゴミ収集車両で経験される制動サイクルの高い数から取り戻されるエネルギーを保存するために、ニッケル水素（NiMH）バッテリーまたはウルトラキャパシタパックを使います。HEVは、能力をリアルタイムパフォーマンス監視と遠いトラブルシューティングに提供している積載されたGPSとRemote Diagnostic Unit（RDU）を使用もします。RDUは、場所、車両ステータスと申し込みウェブに基づくアクセスを伝えます。

Crane Carrier Teams With ISE Corp and Bosch Rexroth to Build Hybrid Trash Trucks to Reduce Fuel Use by 30-50% for NY, Chicago and Houston

PASADENA, Calif.--(BUSINESS WIRE)--CALSTART’s Hybrid Truck Users Forum (HTUF) Refuse Working Group announced today that its members have selected the supplier team of Crane Carrier/ISE/Bosch Rexroth to negotiate with for validation and testing of Class 7 & 8 heavy duty hydraulic hybrid and electric hybrid refuse vehicles.

The hybrid trucks are expected to yield 30 percent to 50 percent reductions in fuel use with an accompanying reduction in emissions, to be demonstrated in chassis dynamometer and field testing. The working group members taking part in the hybrid refuse truck pilot project include the Department of Sanitation, City of New York; Solid Waste Management Department, City of Houston; and the City of Chicago.

"In the pioneering spirit of New York City, the Department of Sanitation is proud to be an early adopter of heavy-duty hybrid technology. We are committed to working with partners in developing new and innovative technologies that will benefit not only our city's environment, but our country's, as well," said Sanitation Commissioner John J. Doherty.

Crane Carrier Company, working in conjunction with ISE Corporation, proposed a series hybrid electric refuse vehicle (HEV) using a self-contained hybrid drive assembly that can be easily mounted between the frame rails in most truck chassis. It replaces the conventional manual or automatic transmission assembly in the Crane Carrier LET2 chassis. The proposed HEV system uses components that have already been developed by ISE for the transit market in heavy 60 ft. articulated bus applications. The HEV will use nickel-metal hydride (NiMH) batteries or ultra-capacitor packs to store energy recovered from the high number of braking cycles experienced by refuse collection vehicles during their normal operation. The HEV will also employ an onboard GPS and Remote Diagnostic Unit (RDU) providing the capability for real time performance monitoring and remote troubleshooting. The RDU conveys location, vehicle status and offers web-based access.

Crane Carrier and Bosch Rexroth Corporation have proposed using Rexroth’s Hydrostatic Regenerative Brake (HRB) parallel hydraulic hybrid system to power their LET2 chassis. The HRB system will be integrated with the Heil refuse body hydraulic system for weight savings and more efficient packaging. The HRB system uses a hydraulic pump/motor, connected to the driveline, to capture kinetic energy during vehicle braking. When braking, the pump/motor acts as a pump, absorbing energy from the driveline and imparting a retarding force on the drive wheels. The absorbed energy pumps hydraulic fluid into a nitrogen-pressurized accumulator. During acceleration the pressurized gas pushes fluid out of the accumulator and the pump/motor now acts as a hydraulic motor, assisting the engine and reducing the fuel required to launch the vehicle.

About CALSTART’s Hybrid Truck Users Forum (HTUF)

The national Hybrid Truck Users Forum (HTUF) program is a partnership between CALSTART and the U.S. Army TARDEC’s National Automotive Center (NAC). HTUF works to speed the commercialization of hybrid drivelines that could be used in both military and commercial vehicles. The HTUF program currently works with more than 80 fleets representing roughly one million trucks. Truck hybrids are emerging as a U.S.-led technology: there are already more than ten leading U.S. manufacturers of heavy-duty hybrid propulsion systems.

The HTUF Refuse Working Group is building on the success of the HTUF Utility Truck Working Group and its deployment of 24 International Truck/Eaton hybrid electric “bucket” trucks, which has led to the early production of Class 6/7 hybrid trucks by International and the development of similar vehicles by Peterbilt, Kenworth and Freightliner.
