Track shoes (also called track pads or track shoes plates) are metal plates bolted to links in order to provide the contact point between the ground and a track chain, providing traction and flotation in excavators, bulldozers, cranes and drilling machines. Track shoes are manufactured with heavy duty rolled steel profiles, then undergo hardening and stress relieving processing in order to ensure the wear, high strength, and resistance to bending and breakage for a longer track pad life that customers have come to rely on. Single, double and triple grouser designs, with or without mud holes, and standard and extreme service profiles, as well as a wide range of shoe widths all combine to provide an excellent machine performance. From high penetration and traction, to low turning resistance for a greater maneuverability.
Types of Track Shoes
Smooth track shoes do not have claws and are utilized in duties that require walking on paved or asphalt surfaces because they reduce the amount of damage caused by the vehicle's footprint.
Another goal is to create a vehicle track chain that is designed and built to last longer than current chains, especially so that the comparatively moveable elements of the chain do not become materially worn even when the vehicle travels over sandy or gritty ground.
Because of their high ground penetration rate, they have the best traction of any shoes. They're employed in harsh areas where there's a lot of rock. On the one hand, front track tractors and angular dozers are common examples of machines with this configuration. On the other side, because of its high penetration, the vehicle's mobility when making turns is reduced.
They're thought to be the best choice for work in semi-abrasive conditions or on relatively soft soils. Although the two grouser shoe design gives less traction than the single grouser shoe, it increases machine agility when completing turns by reducing ground resistance.
These will provide traction, maneuverability, depth, and pressure on the ground features that will greatly assist the operation in various job situations, resulting in cost savings by reducing wear.
This is the most common shoe configuration among excavator manufacturers; the level of penetration exhibited by this class is the lowest among those with claws; as a result, this type is ideal for performing work on soft soils by improving the equipment's maneuverability to execute turns. Traction, on the other hand, is diminished.
Other shoe designs include triangular-style designs for wetland uses, rubber to substantially reduce the vehicle's footprint on the pavement when gardening, and so on.
An infinite track with tubular bodies connected to neighboring chain links by connector links is enlarged by at least one more tubular body and one more connector link, all tubular bodies and connector links preferably being of uniform basic dimension as perceived in the direction of movement.
When compared to traditional vehicle tracks, an endless track for a track-laying vehicle has a construction that allows for easy replacement and maintenance of track components, as well as a longer lifetime of usage.
What Are The Characteristics Of Track Shoes?
Commonly used track shoes are classified according to the grounding shape, there are three types of single rib, three ribs and flat bottom, and some of them also use triangular track shoes. Single-reinforced track shoes are mainly used for bulldozers and tractors, because this type of machinery requires the track shoes to have a higher traction capacity when working. However, it is rarely used on excavators. This type of track shoe is only used when the excavator is equipped with a drill frame or requires a large horizontal thrust. A higher traction is required when turning from a child, so a higher crawler bar (ie, a crawler spur) will squeeze away the soil (or ground) between the crawler bars, thereby affecting the mobility of the excavator.
Steel track shoes can be divided into: excavator plates and bulldozer plates. These two are the most commonly used, using section steel as the raw material. Then there is the wet floor used by bulldozers, commonly known as "triangular plates", which are cast plates. Another type of casting slab is used on crawler cranes. The weight of this slab can be as little as tens of kilograms, and as many as hundreds of kilograms.
The primary function of track shoes is to provide grip and traction, enabling the excavator to move smoothly and efficiently on different surfaces. They help distribute the excavator's weight evenly, reducing ground pressure and minimizing damage to sensitive surfaces. The design of the track shoes, including the shape, size, and pattern of the grousers (protrusions on the shoes), plays a crucial role in determining the excavator's traction and performance in specific ground conditions.
The track shoe is attached to the links usually using 4 bolts and 4 nuts. There is a wide variety of shoes with various widths and grouser shapes. The track shoe is made up of a plate which supports the full weight of the machine, and a claw that has the objective of exerting traction on the surface of the ground. During operation, the track shoe must overcome stresses such as that caused by the bending force, a frictional force that generates wear and tear. Therefore, track shoes are designed to withstand high loads and with resistance to friction wear. In the design stage, studies and simulations are carried out so that in operation it is avoided that rocks and sand are trapped between the footings.
The purpose of Track Shoes
Most excavators use three-reinforced track shoes, and a few use flat bottom track shoes. When designing a three-reinforced track shoe, firstly find the ground contact pressure and the meshing soil capacity between the track reinforcement and the ground to ensure the necessary adhesion; secondly, the track shoe should have a higher bending strength and abrasion resistance. Three-reinforced track shoes generally have two mud cleaning holes. When the track shoe rotates around the drive wheel, the silt on the chain track section can be automatically cleaned with the help of the gear teeth, so the mud removal hole should be located between the two screw holes that fix the track shoe on the chain track section.
For crawler walking devices used in marshes or farmland, in order to protect the ground surface and reduce turning resistance, it is more appropriate to use extended crawlers and flat-bottomed crawlers. In order to ensure that when the track chain is at any position (including grounding, rotation around the driving wheel and guide wheel, and upper suspension position), the adjacent track shoes will not be caught between stones and cause excessive stress.
The distance is adjusted very accurately, and the lap lip of the appropriate shape should be designed. The function of the overlap lip is to make the track shoes close to each other, forming a belt shape that connects end to end. The track shoes should be installed sequentially in the same direction. The smaller the pitch of the track, the smaller the increase when the track chain runs between the driving wheel and the guide wheel. In this way, the running uniformity is good, the wear of the crawler chain is low, and the driving efficiency is high when walking. But the minimum pitch value should be determined according to the machine weight and the number of rows of the crawler chain. The hole spacing on the two rows of chain rails for installing track shoes should generally be larger, so that track shoes with different ground pressures can be replaced.
Common Problems of Track Shoe Assy For Komatsu
Q: What is the function of track shoes?
Q: How to choose shoe width wisely?
A shoe that is too narrow will cause the machine to sink. During turns, the back end of the machine slides, causing excess material to build up on top of the shoe surface which then fails into the link-roller system as the machine continues to move. Tightly packed material built up on the roller frame may cause reduced link life due to the link sliding across the packed material, which may also cause the carrier roller to stop turning;
However a slightly wider shoe will give better flotation and accumulate less material because the material is farther away from the link-roller system. But if you choose shoes that are to wide, they may bend and crack more easily, cause increased wear on all components, may cause premature dry joints, and may loosen shoe hardware.
Q: What happens if the shoe assembly is installed in the opposite direction?
If the shoe is placed in the opposite direction, the teeth of the sprocket will engage in the link bushing at the bottom of the sprocket, on the other hand, when installed in the proper position, the coupling occurs in the part top of the wheel.
Due to the position of the shoe, sand and dirt may enter between the bushing and the teeth of the sprocket, causing wear on both.
Because the track link is screwed to the ground, it produces an unwanted movement that significantly reduces the traction force.
Q: What is an excavator shoe?
Q: What is the difference between a bulldozer and an excavator Track link chain assembly Chain?
Bulldozer is mainly walking work, its weight of more than 20 tons plus full load thrust is very large, It is mainly through the horizontal pull of the chain to make the vehicle walking work, so the general performance of the bulldozer chain is better than the excavator, Material quality is generally wear-resistant 3MnB steel forging.
There is a gap between the weight and the cross section of the chain. It is a waste of the bulldozer chain when it is used on the excavator. It will take less than long for the excavator chain to be used on the bulldozer.
Q: How to maintain Track Group
Clean up gravel
Working in a mine environment, Worst wear on track shoes. Gravel sometimes gets stuck in the gap between two boards when working, When it comes into contact with the ground, it will produce impact pressure on the two plates. Track shoes are prone to bending and deformation, and long-term working will also cause cracking problems at the bolts of the track shoes.
Avoid excessive track tension
The chain link is in contact with the driving ring gear and is driven by the ring gear to rotate. Excessive track group tension will cause early wear of the chain link, sprocket and idler.
