The new Caterpillar® 938H wheel loader and IT38H with integrated toolcarrier linkage feature the Cat® C6.6 engine with ACERT® Technology for responsive power and low emissions. The new engine, differential lock system, load sensing hydraulics and increased lift and tilt forces deliver high performance in digging and material handling applications while limiting engine emissions to meet U.S. EPA Tier 3 off-highway emissions regulations and worldwide emissions standards.
The new loaders also feature the Cat Fusion™ Coupler System. The coupler design pulls the coupler and work tool closer to the wheel loader for nearly full machine performance with the expanded versatility and flexibility of a coupler. The patented design moves the center of gravity closer to the machine, yet the coupler enables the loader to conveniently pick up and use a wide range of work tools. Also, the new, open frame design gives the operator excellent sight lines to the work tool and load.
The loaders also have new features that aid machine health monitoring and service. The in-cab Messenger display provides real time machine performance, engine and diagnostic data to help maximize productivity and component life. The hydraulic and electrical service centers group service points and offer easy access from ground level to limit service downtime. Cat Product Link is standard on the new loaders. The system provides two-way information flow between the machine and Caterpillar dealer and to the owner’s desktop computer through the online dealer storefront.
Automatic differential lock on-the-go
The 938H and IT38H have a new axle with standard front differential lock or an optional, automatic differential lock for both front and rear. Fully locking differentials on both front and rear is exclusive to Caterpillar among all competitors. Differential lock replaces limited slip and offers the advantage of reduced fuel consumption and less heat generated in the axle while delivering improved traction and reduced tire wear. The automatic differential lock monitors machine operation and locks during the dig cycle and when tires slip. Both manual and automatic differential lock can engage on the go.
The 938H retains the traditional Z-Bar linkage for excellent bucket loading and optimum durability in digging applications. The IT38H features integrated toolcarrier linkage, which is designed for expanded versatility. It has parallel lift for pallet fork use and other material handling tasks. It is ideally suited for applications where different jobs are performed with one machine using a variety of work tools, such as a bucket, pallet forks and a material handling arm. A quick coupler that can be activated from within the cab is available for fast work tool changes. And for expanded versatility, the modular hydraulic valve design allows field retrofit of third and fourth functions for operating hydromechanical work tools, such as rotary brooms.
The 938H and IT38H build on the productive G-Series machines, the 938G II and IT38G II, which the new loaders replace. Both new machines have net engine power of 180 horsepower (134 kW) with peak engine power maintained through a broader engine speed range as compared to the previous models—about 8 percent more power at 2100 rpm. Bucket capacities range from 3.0 to 3.9 cubic yards (2.3-3.0 cu m) for the 938H and up to 3.0-7.0 cu yd (2.3-5.4 cu m) for the IT38H in low-density bulk material handling applications.
