What is a towline and what does it do?

A pulley system is an unusually large agricultural machine used in civil engineering, mining and excavation. The largest types of dredgers are used in strip extraction to produce natural phosphates. These are among the largest types of mobile devices and can weigh over ten thousand tons.

 
 The bucket line bucket system consists of a large bucket suspended from one arm. The cube is moved by many cables, chains and ropes. The hoist rope, which is operated by a diesel or electric motor, carries the hub and the mast coupling. With the set retaining wire, the cube assembly is pulled horizontally. Thanks to the clever maneuvering of the hoist and tow rope, the bucket is controlled for different operating modes.

Dragline operations

In a typical excavation cycle, the spoon is placed on the peeling material. Then the bucket is lowered and the pull rope is pulled so that the bucket is pulled onto the ground surface, digging deeper and deeper as the bucket gets closer to the main body of the dredge line. the end of the bucket. Cycle. The lifting rope system raises the bucket. Then, a turning operation is performed using the main body of the pulling line to pivot on the supporting shaft to move the giant spoon. The tow rope is released at the right time, tilting the bucket and forcing the bucket to empty the load of material into the bucket, commonly referred to as tipping.

Dragline limits

The limits of the dredge line are the height and length of your dam, as this limits the areas where the transmission line can dispose of waste. Since the towline is design-related, it is more effective if the material is dug below the level of its orbits, as is the case with strip extraction. Guides are not suitable for loading stacked materials. Despite their limitations and high capital costs, resistance to phosphate mining remains very popular due to its low disposal costs, performance and reliability.

Several dismantling sequences

Draglines also use multiple cut sequences or "methods". Each of these extraction sequences is very functional and is still useful today.

The first is the side casting process, which uses "shifted" benches. In this method, the water jet material of the barrel is laterally overloaded and creates a "mud mixture" to transport large amounts of material to the phosphate plant.

The second method is a key handover. This passage cuts a key at the top of the new "high wall" and moves the bench further towards the bottom wall. This may also require a cut when the wall is blocked. A cut means that the cube falls diagonally on a "high wall" to remove the surface.

The next method is the slowest, called a block step. However, this method shifts most of the material. To get past the blocks, the key must be used to access the bottom of the material, and it must be raised to destroy it or raise it to a high level. If necessary, the final cut is pulled back and the material pulled to the side of the "low wall".

For the extraction of phosphate bands or for the degradation, it is good to have resistance lines. You can move large quantities of material in a short time and are ideal for digging deep holes in the ground. Thanks to its reliability factor, the excavator can produce thousands of tons of rock phosphate every day of the year. The extraction of the phosphate band is carried out by various methods for extraction of soil materials, as shown above. The phosphate industry relies heavily on the dredger to continue to mine large amounts of overburden and promote phosphate rock just below the surface.
