2014 VDMA MINING SUPPLEMENT | VDMA 61 The concrete spray machine BSG 8 is equipped with a Deutz diesel engine with an output of 115 kW at 2,300 rpm. The speed of the vehicle can be infinitely adjusted in both directions (0-12 km/h) by means of a hydrostatic drive. The core of the spraying train is the concrete spray manipulator consisting of a rotating column, a telescopic boom and a spray manip- ulator. The rotating column is positioned on a pivot table and can be hydraulically pivoted laterally together with the telescopic boom and manipulator alongside the catenary. The rotating column at the front end of the machine operates hydraulically, permitting 360° rotation and worm drive. A three-stage telescopic boom (2.9-m telescopic length) is attached at the upper end of the rotating column, which can be extended, raised and lowered wit h the aid of a hydraulic cylinder. The manipulator, with a spray capacity of 7.5 m," consists of two hy- draulic pivoting drives, which move the spray nozzle into the required position. The nozzle has a pivoting range of 360° along its longitudinal axis and 240° around its transverse axis. The hydraulically driven rotary vane compressor with an air flow of 7.5 m 3 per minute (operating pressure 8 bar) ensures that the concrete is sprayed by compressed air from the nozzle to the rock face. An ad- justable liquid metering system enables a range of different additives, such as curing accelerators, to be used. What is more, the BSG 8 has an accelerator tank for liquid additives with a volume of around 100 liters. The degree of liquidity of the concrete can be adjusted by the 24- volt electric pump. The B SG 8's integral cleaning system consists of a hydraulically driven high-pressure cleaning unit with an output of 200 bar and a tank that holds 200 liters of water. To improve its stability, the BTG's pivot table can be supported by hydraulic supports on the floor adjacent to the track vehicle or between the rails. The concrete mixer and concrete pump are positioned on the trailer. The concrete mixer, with a drum volume of 5 m 3 , works by the post-mix- ing method, whereby finished concrete is kept mixed. The mixing drum is hydrostatically driven by the spray machine's diesel engine. The sta- tionary drum is charged through the upper manhole and the closing lid plate is opened to unload. The concrete pump is located underneath the reopening plate and works as a piston pump, which is also hydraulical ly driven by the spray machine's diesel engine. A concrete hose connects the spray nozzle to the spray manipulator. The rail vehicle's mixing drum can also be charged by a mobile concrete mixer truck, by driving the mobile mixer to the con- crete pump and transferring concrete into the concrete pump. The quality of the machine components makes the vehicle ideal for use in extremely damp and seriously wet environments. The rail vehicle is equipped with an open and comfortable cab located in the center of the concrete spray vehicle. All steering and control equipment is clearly arranged in the cab. Convenient access is possible from both sides and a cushioned driver's seat and comfortable and easily reachable controls continue to win over users. VDMA The Paus PFL8 now operates with Canbus, a z-linkage and a new engine.
