CASE WX155E SR Wheeled Excavator

The CASE WX155E SR is specifically designed for the demanding needs of road builders, municipalities, infrastructure utilities, and demolition crews. This wheeled excavator offers swift, smooth, and smart features, manufacturer productivity, and efficiency on any jobsite.

Performance

At the heart of the WX155E SR lies a powerful 170 hp engine, free from Exhaust Gas Recirculation (EGR) complexities, ensuring lower maintenance and operational costs. The engine boasts an automatic after-treatment system cleaning feature. It offers four user modes — including a customizable one — allowing operators to fine-tune performance, power, and fuel efficiency to suit specific job requirements.

Mobility

Designed for optimal mobility, the WX155E SR features four lower-frame configurations with various combinations of dozer blades and stabilizers, twin tires for reduced flat tire downtime, heavy-duty axles, and a hydrostatic transmission that allows up to 25 mph speeds. Standard cruise control and Ride Control smooth out travel, while a trailer hitch facilitates easy transport of attachments and materials.

Versatility

The standard two-piece boom enhances the excavator’s agility, enabling operation in tight spaces and close to the machine. An optional monoboom provides a traditional operating experience for tasks requiring greater lift capacity. Joystick steering ensures precise low-speed maneuverability. The high-flow hydraulics support one-way and two-way attachments, with an optional excavator’s circuit for delicate operations. A Leica 2D Precision package and various attachments extend the machine’s utility from asphalt cutters to pallet forks.

Comfort

Operator comfort is prioritized with features like expansive glass for superior visibility, an air-suspension heated seat with extensive adjustability, and an 8″ touchscreen display for easy access to machine controls and camera views. An optional smart ignition key with push-to-start enhances security, and the machine’s Auto-Braking feature boosts confidence and efficiency during repetitive start-stop tasks.

Serviceability: Maintenance is straightforward, with extended service intervals for engine oil, fuel filters, and hydraulic oil. A 3-year/3,000-hour full machine warranty and a 2,000-hour maintenance plan support this. Most consumables are easily accessible for ground-level servicing, simplifying upkeep and minimizing downtime.

Safety

Safety features include standard rear radar object detection and the CASE maximum view monitor system, which offers 360-degree visibility and intelligent object detection to ensure operational safety in all conditions. Hose burst check valves on critical hydraulic cylinders provide an added layer of protection, and optional cab reinforcements are available for heightened operator safety.
