CATERPILLAR has introduced the new Cat® 301 Compact Radius (CR) micro hydraulic excavator, designed to deliver improved performance in confined spaces. Announced on October 7, 2026, the new model is developed for contractors who need a compact, versatile machine capable of handling demanding tasks in restricted working environments.   Compact Design for Confined Spaces   The Cat 301 CR is designed for indoor demolition, landscaping, agricultural work and other applications where access is limited. Its compact radius design minimizes machine overhang, allowing operators to work closer to fixed structures. The excavator can pass through doorways measuring just 762 mm wide and 1,981 mm high, with its rollover protective structure folded.   The expandable undercarriage provides flexibility when moving through narrow access points and helps improve stability during operation. Compared with the Cat 300.9D, the new model features an undercarriage that is 26% wider when fully expanded and offers more than 80% greater lift capacity.     Enhanced Performance and Operator Convenience   The Cat 301 CR combines practical design features with improvements in digging, lifting and travel performance. Its maximum operating weight is 1,230 kg, while its travel speed reaches up to 3.6 km/h. The machine also features a maximum bucket force of 9.6 kN and a stick force of 6.2 kN.   Operator-focused features include a simplified instrument display, side-mounted joystick controls and a standard LED boom work light. The foldable ROPS supports access through height-restricted openings, while the tilt-up seat provides easier access to the engine compartment and key service points.   A closed-loop swing system is designed to support faster cycle times and improved energy efficiency. In addition, the machine's auxiliary hydraulics and attachment options allow it to handle a variety of tasks, including trenching, drilling and breaking concrete or asphalt.   Versatility for Different Jobsite Requirements   The Cat 301 CR is compatible with a range of purpose-built attachments, helping contractors adapt the machine to changing jobsite requirements. Its quick attachment-change system is designed to simplify tool changes and reduce downtime between tasks.   As construction projects increasingly require equipment that can operate in restricted spaces without sacrificing versatility, compact excavators remain an important solution for contractors, landscaping professionals and utility crews. With its expandable undercarriage, improved lifting capability and operator-friendly features, the new Cat 301 CR expands CATERPILLAR's compact equipment offering.   For further information about specifications, attachments and regional availability, customers can contact an authorized CATERPILLAR dealer or visit the company's official website.  

Winter mornings bring a familiar frustration to construction sites: the excavator turns over but won't fire. The battery is charged, the starter works, but the engine refuses to catch. In most cases, the problem isn't electrical—it's the fuel in the tank.   Diesel fuel contains paraffin wax that crystallizes as temperatures drop. When diesel cools below its cloud point, wax crystals begin to form. Below the pour point, the fuel thickens enough to stop flowing through filters and fuel lines entirely. For 0# diesel, the pour point sits around 0°C, and gelling can begin at temperatures as mild as 5°C.   Manufacturer winter maintenance guidelines from SHANTUI and industry practice recommend selecting diesel grades based on local minimum temperatures, not average conditions. The pour point of the fuel should sit 4-6°C below the lowest expected temperature. In southern regions with mild winters, -10# diesel provides adequate protection. In northern China and severe cold zones, -20# or -35# grades are required.     Fuel system care extends beyond grade selection. Filling the tank at the end of each shift reduces the air space inside, which limits condensation on the tank's inner walls. Water accumulation in the fuel system accelerates filter clogging and corrosion. Operators should also check water separators daily and drain any accumulated moisture before it reaches the injection system.   A final consideration is fuel filter replacement. Cold fuel is thicker and passes through filters more slowly. A partially clogged filter that performs adequately in summer can restrict flow enough to prevent starting in winter. Replacing fuel filters before the cold season begins is cheap insurance against a no-start morning.   For fleet managers, winter diesel management is a planning exercise. Match the fuel grade to the forecast, fill tanks at shift end, and replace filters before the first freeze. None of these steps takes more than a few minutes, but together they keep machines starting on the coldest mornings.
