Volvo Construction Equipment introduces the BL70 backhoe loader that features a patented safety feature to help reduce risks of downtime and the loss of revenue from overheating problems. VHSS, the Volvo Hydraulic Safeguard System, monitors the hydraulic oil temperature to prevent overheating. If the oil temperature rises above 207 degrees F, the hydraulic functions automatically go into “loader mode”: 40 hydraulic hp instead of the normal 62 hydraulic hp. Operators can continue to work without stopping the machine and a white VHSS light will illuminate during this phase. The onboard computer continues to monitor status every seven minutes and automatically adjusts the power to optimize the cooling performance. When the temperature falls below 207 degrees F, hydraulic functions return to “backhoe mode” at 62 hydraulic hp. If the temperature continues to rise, a separate high-hydraulic temperature (red) light illuminates and a buzzer sounds, telling the operator to stop using the hydraulics immediately but keep the engine running. The benefits of this system include longer oil and seals life, the machine never stops working, reducing the risk of overheating and it gives operators the ability to work in high-ambient, high-altitude and high-humidity conditions.
