Tips for keeping your vacuum excavator in peak winter condition
When cold weather conditions set in, regular maintenance and a heightened awareness of how to keep vacuum excavation equipment operating properly is required to avoid costly repair expenses. In the oil and gas market alone, there are thousands of vacuum excavators at work in oil fields across North America, and a majority of these units are working through the winter in extremely cold conditions.
It’s important to follow all winter maintenance recommendations as outlined in the operator’s manual. These will generally include the following tips:
The service technicians at your equipment dealer can also provide helpful advice. Beyond the basic winter maintenance tips, Vactor Manufacturing offers some additional recommendations to keep your vacuum excavation equipment operating efficiently throughout the winter.
Consider cold weather truck options
For vacuum excavators, digging in extremely cold temperatures or air excavation can provide the most stress on the equipment. Not all equipment is designed to operate in cold temperatures. Vactor vacuum excavation trucks are designed to operate efficiently in temperatures as low as minus 40-degrees F (minus 25.5-degrees C).
Vactor offers a number of cold weather options, including heated storage, heated water pump and water heater cabinets, toolbox heaters, and warming cabinets. Vactor vacuum excavators featuring the Kenworth T880 chassis can be equipped with an arctic package including a block and pan heater, heated fuel water separator, coolant tank heater, battery pad heater and arctic hose options for colder extremes.
It’s important to prevent the water system on your vacuum excavator from freezing. The Vactor HXX water tank is manufactured from HDPE which retains heat in the cold winter months better than steel or stainless steel materials traditionally used in other equipment. The tank water can also be preheated through the onboard water heater that is capable of 800,000 BTUs. For extreme applications, the Vactor HXX is also available with a heated debris body to prevent excavated material from freezing up and greatly improving material offloading in the cold winter months.
Before, during and after the job
Visibility is important
For the safety of the operator – and any others on the jobsite, or on the road when traveling to and from the job – good visibility is essential. Keep the windshield wiper fluid tank full with a winter blend to prevent freezing, and install winter weather wiper blades to help keep snow and ice off the windshield.
Proper lighting is also important for enhanced visibility, especially during the winter months when the days are shorter and sunlight is minimal. When driving in snow, vacuum excavators and other vehicles can be hard to see, so it’s important to include additional lighting on the truck beyond the standard clearance lighting to increase visibility. Additional work lights should be installed on vacuum excavators to enhance visibility to the site when working in the early morning or evening hours and when working in snowy conditions. For added visibility and safety, operators should also wear reflective gear over their clothing.
Always be prepared
Depending on the job, a vacuum excavator operator might be working in very remote locations, far from the closest town. They might be facing steadily dropping temperatures, with snow and ice in the forecast. With this scenario in mind, Vactor recommends keeping an emergency survival kit in the truck that includes extra hats, gloves, gaiters and other winter clothing; blankets; food and water; flashlights; batteries; matches; emergency flares and first-aid kit.
Vacuum excavation equipment requires thorough maintenance to keep it running smoothly year-round, and especially during the winter months. Winterizing equipment – and taking the necessary steps before, during and after operating in winter conditions – ensures efficient performance and maximum uptime, and protects your investment. CUI
