With the breakthrough of the last two tunnel boring machines into the target pit in Oberhausen-Biefang on June 12, 2017 the tunnel and pipe jacking work for the Emscher sewer has been completed. Over a period of 25 years numerous Herrenknecht tunnelling machines and a wide range of additional equipment were successfully used in the Europe-wide unique environmental and sewage project of Emschergenossenschaft.
The Vermeer MEGA VAC VXT truck series by McLaughlin is a highly productive vacuum excavator designed to meet increasingly strict weight restrictions and regulations. Ideal for utility and distribution contractors, the VXT Series is a reliable, cost-effective solution for high-production potholing crews. The new 6-inch (15.2 cm) PTO-driven series comes in three standard spoil capacities ranging from 1,200 to 2,000 gallons (4542.5 to 7570.8 L). The VXT series is powered by the industry-proven OMSI Gearbox and a ROOTS 3200 CFM (91 m3/min) blower. The new CAN Control system allows for two-way communication between the remote control and the vacuum excavator, which helps contractors increase jobsite productivity. The new Vacuum Neutral feature allows the blower to breathe free air and stop suction without the need to close the hydraulic gate valve in the boom.
