Take this example in Durban, South Africa. When storms turn the hard-packed surface of this storage area into a mud bath Teletruk’s 4 x 4 transmission really pushes the boundaries of what’s possible. This is one of two 35D 4x4s working for warehousing and distribution company MGI Freight Management. The company stores and loads spun concrete pipes onto flat bed lorries a short distance from the main warehousing and distribution business. 4 x 4 in 2.50m aisles Teletruk 35D 4 x 4 in Weir Group's foundry, Johannesburg, South Africa. This Teletruk collects resin-bonded silica sand for screening and re-use in the moulding process. The essential ability is to negotiate narrow aisles which reduce to only 2.50m width on the final approach to the screening machine. The foundry produces over 100 tonnes of specialised castings a month for the Weir Group's range of pumps and valves machined and assembled on the same site. The pipes are 6m long and range in weight from 1 tonne for the biggest diameter single pipe to packs of smaller diameters up to 2.4 tonnes. The Teletruk’s back-tilt of 16 degrees is used to hold loads secure at the heel of the forks carriage. This 4x4 Teletruk works in wet, difficult conditions alongside huge loading shovels and dump trucks at the century-old Piketty Quarry near historic Fontainbleau, south of Paris. A shovel is fitted for clean-up work near the conveyor screens. This is changed for forks inside the bagging plant. Piketty Quarry processes 600,000 tons of limestone per year, a third of it by crushing.

The imported raw vermiculite base product is sourced from a variety of mines in China, Africa and chiefly from the highest quality Palabora mines in South Africa. Because it is delivered either by flexible bag or loose both a forklift and a loading shovel is required. Both these requirements for feeding the hopper with various grades, either loose or bagged at the start of the production line, are answered by a single Teletruk 35D 4 x 4. The UK plant stores loose product in one of 3 large bays for different grades and quality able to hold 400 tonnes. Product also arrives in standard one tonne flexible big bags or also in 1200 kg bags which are taller at 1300mm. The bags have an exit at the base, whereby the vermiculite is vented into the hopper by manual release of a flexible sealing chute. Smaller, 50% less fuel, same load capacity Big wheeled loading shovels are familiar workhorses in the many factories of Brazil. But now industrialists are discovering little Teletruks can do the same jobs in less space, and with less fuel. Mário Neves of JCB dealer Auxter in São Paulo City says: “Our photo shows a 3.5 tonne capacity 4 x 4 Teletruk alongside a much bigger 4 x 4 Michigan HT Loading Shovel in Sorocaba, one of our leading industrial towns in São Paulo State. Our customer Dibloco was using the HT Wheeled Loader for all materials handling in the various processes of manufacturing concrete breeze blocks. But now the little Teletruk has replaced the Michigan for most work due to its small size and forwards reach. The blocks are made on metal sheets, stacked in frames and moved to a shed to dry. Then they are taken off the trays, put onto pallets and loaded onto trucks. The metal plates and stacker frames are taken back to the block press. The customer prefers the Teletruk as it uses about 50% less fuel which is better for the operators because emissions are reduced. When fitted with forks the Teletruk and the Michigan Wheeled Loader will lift virtually the same, so why use a big machine ? ” The loose material is delivered to the hopper by means of a JCB Bagezee 'Trapdoor' shovel. The Teletruk switches between Bagezee and the flexible big bags by manual Changezee quick-disconnect carriage. The required load-over clearance height for the 1300mm bags above the 3m hopper lip is achieved by rotating the forks 180 degrees. Back tilt is easily achieved in this position by the Teletruk's tilt carriage. A small amount of forwards reach on the boom is required to clear a floor mounted protection barrier in front of the hopper structure. Whilst the floor surface is new and high quality the traction of a 4 x 4 Teletruk is required to cope with the dusty floor environment, and particularly the gradients down into the bays and also down to the feed hopper. The process plant extracts geologically locked-in moisture. The resulting finished product is sold into numerous applications around the world which need the insulation properties of vermiculite plus its natural resistance to combustion at very high temperatures. Now the Michigan does little work. With a shovel it loads hoppers about twice an hour with sand. Also when the Teletruk is too busy inside the plant forks are fitted and it sometimes loads trucks with pallets.
