Caterpillar introduces new mini-hydraulic excavators Cat "C" series weighing from 1,7 to 2,8 tons of high strength design and good performance characteristics. The new mini-hydraulic excavators series "C - 301.6C, 301.8C and 302.5C - have increased, as compared to previous models, the stress of digging stick (10%) and bucket digging force (22%). Changes in the design of machines to prolong their service life on the site. Machines of new models also have higher productivity due to the flow and pressure of hydraulic fluid in the hydraulic system and increased engine power by about 4% - to 13,5 kW (18,1 PS) on the machines 301.6C and 301.8C and up 18,6 kW (24,9 hp) car 302.5C. Make improvements helped reduce the duration of cycles and increase productivity while simultaneously meeting the requirements of the second phase of European standards on toxic emissions (EU Stage II). New hydraulic pump with a regulated supply eliminates machine stops due to overload and allows the excavator to work in very difficult circumstances. To reduce the cost of running the machines are equipped with side panels with increased strength 5 mm thick and large intact opened outside the back door. As the rear corner of protective structures used solid casting for protection against shock impacts on the site. In the model 302.5C installed lifting side panel providing access to the tanks and the hydraulic valve actuator of the working equipment. The increased in all three models up to 500 hours of motor-oil change intervals and filter helps to reduce operating costs. Front lever mechanism made of box-section profile, which provides the necessary performance and increased resource. Arrow with an independent turn allows the machine to work closely with the walls and obstacles, and shovel with a rotation angle of 200 ° provides improved retention of raised soil and the flatness of the execution of the bottom tranches. Choice handles the increased length, in addition to the standard handle, as well as working tools from an extensive range of machines increases the versatility 301.6C, 301.8C and 302.5C. Cabin series machines C is spacious and provides all-round view and good air circulation. Unlike previous models, the cabin has a large floor area, the size of the door increased. To improve ventilation cab window, easily retractable roof space. 302.5C model comes with the factory air conditioning. Seat with suspension, controls the working equipment installed on the remote control, joysticks, operated by small effort, and adjustable wrist supports help the operator to work without fatigue throughout the day. In addition, switches, built-in joystick machine model 302.5C, facilitate the management of turn arrows and accessories. Switch located on the lever blade control and managing system-speed motion control makes the machine speed during bulldozing work, and installs a standard system for the floating regime Blade facilitates the execution of works on profiling. The system control machine is closer to the axis of the review sites, making it easier to view the readings and the warning indicators. Operator's cab is also equipped with mobile phone holder and a source of power 12 V.
