SUCCESS STORY: Hawthorne CAT Builds State-of-the-Art Engine Test Center and On-Highway Testing Facility

Founded in 1956, Hawthorne Cat® is an authorized dealer for Caterpillar® construction and power equipment in San Diego, Hawaii, Guam, Saipan and American Samoa. Hawthorne sells, rents, provides parts and service to various industries including general building construction, landscaping, marine, trucking, paving, power generation and other engine-related markets.

State-of-the-Art Engine Test Center
Due to the large hp engines (Cat® 3516) and genset population in their service area, Hawthorne expanded and modernized its corporate campus in Rancho Bernardo by adding a state-of-the-art Engine Test Center and on-highway truck testing facility. The 5,000 square foot facility has separate bays for engine, chassis, and generator testing. The Test Center features 3 dynamometers from Taylor including the DS4012-HS Engine Dyno which allows engine testing up to 4,250 hp (3,169 kW). A TD-3100 Portable Engine Dyno capable of testing engines up to 1,250 hp (932 kW) and a TD-36 Tandem-Axle Chassis Dynamometer 1,100 hp (820 kW). The testing facility also features Taylor’s highly-engineered facility support equipment including cooling, fueling, ventilation, exhaust, water recirculation system and DynPro2 data acquisition and control system.

Keys to Success
Hawthorne Cat® worked with Taylor Dynamometer in the past and has always had good results. This project was no exception. Taylor worked with the construction team to value engineer the building and systems to help meet Hawthorne’s project budget. Building codes and parking restrictions at the new facility required a lot of the support equipment to be roof-mounted. So Taylor’s engineering team went to work on a roof design that would support the weight of the cooling system’s towers.

Another key piece to the successful implementation was involving Taylor’s Test Cell Design Services from the beginning stages of the project, well before any excavating occurred. This helped to reduce risk, costs and deliver a safe, convenient and well-organized testing facility. Throughout the project, Taylor remained in constant communication with Hawthorne Cat®, the engineering team and construction group to resolve problems before they impacted the schedule, keeping the project on track for their open house.

VIDEO: Custom Mower Deck Test Stand Provides Critical Design Features for the Customer

Dyne Systems recently manufactured a custom mower deck test stand. The mower under test is placed on top of the test stand; the test stand features adjustments to allow for variations in mower wheelbase differences.

The mower deck test stand features three 20 hp (15 kW) low profile AC dynamometers. Each of the three dynamometers couples mechanically to an individual mower deck spindle to provide a controllable load. The dynamometers are mounted on a movable cradle which provides fore-and-aft and side-to-side adjustments. This critical design feature allows the customer to test a wide variety of mower deck configurations.

The AC dynamometers are powered by a high performance liquid cooled AC regenerative multi-drive and individually controlled by a single Dyne Systems’ Inter-Loc V multi-loop dynamometer controller.
