MD-7500 - Mustang's premier diesel fleet maintenance chassis dynamometer

Today’s Fleet Managers are faced with many challenges – most important of which if maintaining a healthy bottom line. With fuel costs at an all-time high, these challenges have become increasing difficult. To help combat these problems and others facing fleet managers today, Mustang Dynamometer offers the MD-7500 Series Chassis Dynamometer – which features the most advanced diagnostic capabilities in the industry. The MD-7500 is designed to simulate the driving conditions that fleet vehicles encounter on the road everyday in a safe and controlled shop floor environment so that critical engine and drivetrain systems can be evaluated to insure vehicles are performing properly and at maximum efficiency. What’s more, the MD-7500 offers several levels of testing capabilities in a modular, compact package and with capabilities that can be upgraded in the future as your needs change.

Every vehicles in your fleet can now be tested and validated before and after a repair to insure proper diagnosis and repairs have been performed. In addition to testing repaired vehicles, the MD-7500 can be used to test vehicles on a regular basis as a preventative maintenance measure; which decreases unexpected breakdowns, and allows fleet management to control fuel costs while reducing repair costs. Periodic testing keeps fuel consumption to a minimum and helps technicians identify suspect components before they fail. A proactive approach to Fleet Service can prevent unexpected engine and or drive-train failure; which saves Fleets thousands of dollars in lost fair revenues.

At the heart of the MD-7500 is a set of three air-cooled eddy current power absorbers. Each absorber, or brake, can hold up to 600-hp (total power of 1,800-hp) – more than enough to simulate a fully loaded transit bus. As the systems PAU’s (brakes) are air-cooled, no water is required to or from the device – eliminating the high cost of water consumption and/or the cost of an expensive water recovery system – which can sometimes exceed the cost of the dynamometer system itself. Mustang is the only company that offers a Universal Fleet Test Bed without water supply requirements. All that is required to run the system is 208-240VAC, three-phase, 40-Amp power.

Each of the MD-7500’s rollers measures 19.75-inches in diameter, which increases tire-roller contact area and decreasing tire wear and tire temperature. Each roller surface is knurled for maximum traction, whilst a belt-drive connects the primary roller set to the secondary roller set – minimizing “rocking” on the rollers and keeping wheels safely centered between the two sturdy roller sets. The MD-7500’s stout frame is fabricated from structural steel for maximum life and durability, while the bearings, couplings, and related mechanical components are machined and over-engineered to insure years of trouble-free operation. Every MD-7500 series dynamometer is individually tested and inspected to insure the highest degree of quality and performance.
