Colmar hydraulic shear specifically designed to cut rails, high productivity. The RP2000 Rail Shear has significant benefits that reduce the cost to the industry. This is achieved by: Significant time reduction for the complete cut and collection process. Reduces the length of possession time for scrap clearing. Eliminates the added cost of secondary machines, operators, attachments, machine controller and risk. Reduction of haulage and transport costs. Typical Operation Performance: We estimate that this shear has the capability, subject to conditions to produce one full cut cycle and move to the next cutting point every 25 seconds. This will significantly reduce the time needed to collect scrap rail which is currently lying out on the infrastructure. Therefore from a productivity point of view, the RP2000 will allow more rail to be collected in shorter possession time. The DAH models range from the DAH-065B, for 5 to 8 tons excavators, the DAH-150Er, for 27 to 35 tons excavators. They can be installed on all mast-type hydraulic carrier with sufficient hydraulic lines, weight, and power. The main advantages of this model lie invisibility, versatility and mobility. With the wide ranges of carrier’s choice and the mulching feats of the DAH, there is no job too hard for a well-equipped land clearing or right-of-way maintenance business. Protective rings that limit the size of the
bites and considerably reduce risks of breakage on the knife holders. Variable displacement, axial-piston
motors that minimize overheating and improve re-acceleration. The industrial cogged belt drive system that prevents slippage and reduces effort applied to bearings compared with V-belts, for longer bearing life. Heat-treated, bolt-on forged knives
that deliver maximum resistance to impact and abrasion, and that can be sharpened right on the unit. Easy-to-replace knives: A single nut and bolt hold the knife in place. Replacing worn knives is a snap. Due to the increased scale of dredging equipment, dredged material is often deposited on sites at a much greater rate than was the case 10 years ago. As a result, there is less time to compact the sand in thin layers and the compaction is forced to take place over thicker layers. Few compaction techniques with a high production rate and a reasonable price are available for these thicknesses. With the development of the CDC technique, Cofra has provided this niche market with a promising technique that compacts the subsoil homogenously and accurately. Depending upon the soil type and the energy input, compaction of the subsoil can be achieved to a depth of approximately 9 meters below the surface. Compaction using the CDC technique takes place from the surface of a site. The CDC machine consists of a hydraulic excavator base with a strengthened arm to which a compaction hammer is attached. Weight within the hammer generates vibration by the repeated drop onto a compaction foot that remains in contact with the ground. These vibrations bring the soil particles into a more densely packed structure. The increased density of the ground both improves its strength and increases the safety against liquefaction.
