Snowplow power unit questions about fit, operation and maintenance

The unit supplies hydraulic functions for truck-mounted skis, including lifting and left-right swing. Different loops and valves can be selected for the hydraulic arrangement. Buyers should match those options to the functions and connections required by the complete snowplow system.

The listed configurations use 12V or 24V motors. The 12V options include motor powers of 1.5 kW, 1.6 kW and 2.1 kW. The 24V options include 2.2 kW, 2.5 kW and 2.7 kW. Pump displacement options range from 1.2 to 2.7 ml/r, and the listed overflow valve pressure is 20 MPa.

Send the truck voltage, required hydraulic functions, pump displacement and pressure requirements when requesting a quotation so the configuration can be matched to the vehicle and snowplow system.

Different pump flow, pressure, motor power and other system parameters can be specified by model. A manual emergency oil release is also available when required, but it should be specified when placing the order. The buyer should provide the truck voltage, hydraulic functions, target flow and pressure, and available installation space.

The power unit should be mounted horizontally. Before installation, clean all hydraulic parts connected to the unit. A buyer planning installation on a truck should also check the mounting surface, hydraulic connections and access for service while keeping the unit in the required horizontal position.

Use clean hydraulic oil free of impurities with a viscosity of 15 to 68 cSt. N46 hydraulic oil is recommended. Picture the first installation as a complete hydraulic-system preparation task: clean the connected parts before mounting, then fill the unit with oil that meets the viscosity range.

The duty is S3: 30 seconds on followed by 270 seconds off. The control schedule for the snowplow system should allow this intermittent operating cycle. It should not be treated as continuous motor operation.

Change the oil after the first 100 hours of operation. After that, change it every 3,000 hours. For fleet maintenance, record the installation or operating hours for each unit so the first change and later intervals are scheduled correctly.

Include the truck's electrical voltage, the lift and swing functions required, the selected or required loops and valves, pump displacement, overflow valve pressure, motor power, tank capacity, mounting orientation and whether a manual emergency oil release is required. The listed tank capacities are 3.5, 5.0, 6.0 and 8.0 liters, depending on configuration, with overall lengths from 411 to 581 mm. Send a hydraulic schematic and available mounting dimensions with the requested quantity for a configuration review.
