Uses
The Allison HT 750 Transmission with Deep Reduction Drive (DRD) is designed for versatility and reliability, offering both automatic hydraulic 5-speed forward and 1 reverse gear as well as a manual hydraulic power shift system. This dual-mode application is ideal for road and work mode, specifically in oil and gas applications where safety necessitates automatic over the road operation while the power shift system is reserved for workover operations that require on-demand gear shifting. Constructed with high-grade aluminum main housings and equipped with the Allison 400 series converter, this transmission offers a range of stall to torque ratios. The standout feature is the Deep Reduction Drive, which is highly sought after for its efficiency and performance.
The HT 750 DRD is a critical component in the oil and gas industry, particularly for well service pumps, mud pumps, workover rigs, and pulling units. This model also supports PTOs off the converter housing, adding to its functionality and appeal for demanding industrial applications.
