Tesmec Trencher 1075 Bucket Wheel Permafrost
The Tesmec 1075 Bucket Wheel model has been designed as a high-productivity trencher for pipelines and utilities projects in dirt and light rocky soils. Its buckets can be equipped with conical or spade tools to ensure the maximum productivity according to the relevant ground conditions. JOBSITE EXPERIENCE IN RUSSIA Project details The job site is located about fifty kilometers from Novyj Urengoj, which is the center of extraction of Russia (approximately 68% of gas and 45% of oil of the entire Russia come from that region). The project entails the creation of a 1,000 km-pipeline from Novjy Urengoj to a location close to Surgut. Pipe diameter is 18’’ with the TRS 1075 digging at 8 ft (2.44 m) deep. Before the arrival of the TRS 1075, drills and explosives were used with excavators cleaning the site. However, this process was slow, expensive in the long term, and inaccurate regarding digging dimensions and directions. Criticalities of the project Actual temperatures ranged between -35 C and -45 C, with peaks at -55C. Due to the marshy nature of the land surrounding the right-of-way , it is necessary to conduct digging operations when the surface and the marshland are completely frozen. Considering the soil conditions and the frequent change of season, which affects the properties of the soil, it requires an excavation of about 1.8 meters for the laying of a 18” pipe in order to avoid the risk of breaches/cracks in the pipe caused by the movement of the pipe itself once laid underground. ***Advantages of Tesmec machines*** Thanks to Tesmec bucket wheel trencher, different goals have been achieved: • Productivity of up to 400m/h. The trencher cuts the minimum required ditch width and yields less cubic meters dug for each linear meter of production. • Possibility of executing a double cut (two parallel excavations) and finishing the digging operations using just three machines: one trencher, one bulldozer to smooth the way for the trencher and one excavator to cover the first dig and later reopen the implemented double dig. This also includes Logistic and Environmental advantages. • Perfection excavation (“rectangular” type, with well established measures and not of “V” type such as that one made by the excavators with inaccuracy), and consequently less material moved. Restoration of ditch is easier and less expensive than excavators because a vertical wall trench requires less backfill material than a “V” wall excavator trench.

NEXTRENCHER's model D-250 is a disc trencher, which installed on an excavator, allows the excavation of trenches up to 80 cm-deep and between 12 and 25 cm-wide. Specially designed for the execution of urban trenches, the model D-250 enables higher performance in this type of works, also on rocky terrain. The disk excavation system executes a clean cut of the pavement according to the dimensions required for the project. Due to its fully enclosed design, the working area and traffic are hardly affected. It also allows the realization of the works in a safe and clean way. The swing system allows a perpendicular orientation of the disk with regard to the excavator in order to make the connections and secondary pipelines from the main pipeline. There are different soil removal and loading options, either by conveyor belt or using a vacuum system. NEXTRENCHER disk usage for the digging of reduced dimensions trenches guarantees the production and security required in these works, increasing the quality and warranty of the pipeline execution. www.nextrencher.com [email protected]

South Africa has a massive skills shortage. One of the most exciting challenges facing the country is that of finding ways and means of upgrading the skills of the population in general, and the skills of those people who lack formal educational qualifications in particular. We need to train more people for a better future, not only for themselves individually, but for their companies and the industries in which they operate. We are confident that we have the necessary resources and competency to execute our program mes with ease for both individuals and corporate clients, most of whom will benefit from them. Mulani has always been committed to skills training and development, we cultivate an awareness of environmental issues and strictly apply training and assessment methodologies.

A robot is a mechanical or virtual artificial agent, usually an electro-mechanical machine that is guided by a computer program or electronic circuitry. Robots can be autonomous or semi-autonomous and range from humanoids such as Honda's Advanced Step in Innovative Mobility (ASIMO) and TOSY's TOSY Ping Pong Playing Robot (TOPIO) to industrial robots, collectively programmed swarm robots, and even microscopic nano robots. By mimicking a lifelike appearance or automating movements, a robot may convey a sense of intelligence or thought of its own. The branch of technology that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing is robotics. These technologies deal with automated machines that can take the place of humans in dangerous environments or manufacturing processes, or resemble humans in appearance, behavior, and/or cognition. Many of today's robots are inspired by nature contributing to the field of bio-inspired robotics. These robots have also created a newer branch of robotics: Soft robotics.

Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.
