Force Control dynamometers featuring Positorq Oil Shear Load Brakes absorb extreme torque at very low speed (down to 0 rpm) so that they can accurately capture data at these critical junctures when dynos equipped with traditional load brakes cannot.
Oil shear technology can provide instant load spikes and static lock-up of up to 3x the continuous load rating. High cycle counts (up to 300 torque changes per minute) allow tests with a hammering effect on the tested product.
Quick, controllable response allows virtually unlimited test capabilities, while their extremely quiet operation allows gearbox, transmission, or final drive noise testing. High-torque, low-speed testing is commonly used for testing life cycles, shock loading, overall machine life/performance, and more for snowmobiles, forklifts, 2-wheel/4-wheel/6-wheel drive tractors or tracked vehicles, commercial truck axles, helicopter transmissions, gun turrets, winches, hoists, and more.
Proven oil shear technology eliminates wear for service-free endurance testing. A variety of sizes and arrangements for shaft mounting, flange mounting, coupled, and vertical/horizontal mounting. Units can be supplied with torque arm and load cell, all controls for the cooling system, and actuation.
