Detailed product information

Material

Rubber material: has good elasticity and flexibility, can effectively soften the blows between the caterpillar and earth, reduce vibration and noise, as well as prevent excessive wear and damage to the earth with caterpillar. Suitable for cases with high requirements for land protection, for example, when working on city roads, landscape territories, etc.

Metal material: usually made of high -strength steel sheets or alloys, has high wear resistance, impact resistance and bearing capacity, can withstand greater pressure and stretching, suitable for use in harsh working conditions, such as mines, construction sites, etc.

Type of structure

The completely closed type: completely covers the outer part of the path, which can protect the path in all directions, prevent garbage from entering the path, reduce wear and damage to the path, and it is better to protect the soil, but installation and dismantling are relatively complex.

The segmented type: consists of several segmented protective blocks, and the number and place of installation can be selected in accordance with the needs. It has high flexibility, easy to install and dismantle, has a relatively low cost, but the protection effect can be slightly lower than that of the type with full coating.

Functions

Protection of caterpillars: reducing friction and clashes of caterpillars with land and obstacles, reducing the speed of wear of caterpillars, increasing the life of caterpillars, reducing downtime and maintenance costs caused by damage to caterpillars.

Protect the earth: avoid direct contact between the path and earth and do not allow the path to cause scratches, dents and other damage to the earth. This is especially important in places where high requirements for the evenness and aesthetics of the Earth are presented, for example, the runways of airports and parking.

An anti -slip properties: some tread of caterpillars have special drawings or protrusions on the surface, which can increase friction between the caterpillar and earth, as well as improve the stability and safety of the excavator movement on wet, dirty and other roads.

Stages of installation

Preparation: Clean the surface of the track from dirt, garbage and oil so that the surface of the highway is clean and even. Prepare the necessary tools such as wrenches, screwdrivers, rubber hammers, etc., as well as tread of caterpillars, corresponding to the excavator models.

Determination of the installation site: Determine the installation site on the rail depending on the type and design of the rail tread. As a rule, a completely closed way of the track must be set from one end of the path, while the segmented protection of the track can be installed in a suitable place, depending on the actual conditions.

Install the tread

Rubber tread: For a completely closed rubber tread, compathes one end of the tread with one end of the caterpillar, then slowly put it onto the caterpillar, carefully tapping it with a rubber hammer to gradually press to the surface of the caterpillar. For segmented rubber tread, compatch the protective unit with the installation site on the guide, and then fix it on the guide using fasteners, such as bolts or clamps.

Metal track protectors: metal treads of rails are usually heavier and for their installation, lifting equipment or several people may be required. First, combine one end of the tread with the corresponding position on the guide, and then, using bolts or pins, fix it on the guide to provide a reliable connection. During the installation, pay attention to the adjustment of the tread position so that it adjacent to the guide.

Checking and adjusting: After installation, check if the tread of the caterpillar is reliable and whether there is a backlash or displacement. At the same time, check if there is a gap or inconsistency between the tread and the caterpillar, and if necessary, perform the appropriate adjustment.

Test launch: run the excavator, let the caterpillar rotate slowly and check if the tread of the caterpillar interferes with other parts, such as the drive wheels, guide wheels, stars, etc. During the trial launch, follow the working condition of the caterpillar tread. If there are any deviations, stop the car on time to check and eliminate the problem.

Common malfunctions

Weakening or falling: fixing bolts or buckles are weakened, which leads to a weakening or even fall of the caterpillar tread during use. Long -term vibration, blows and harsh working conditions can lead to a gradual weakening of the fastener.

Wear or damage: due to the friction and collision of the caterpillar with the ground, as well as interaction with other components, the caterpillar tread can be damaged due to wear, rupture or cracking. Especially when working on solid ground, such as stones and gravel, wear will be more significant.

Deformation: when exposed to greater pressure or impact, the metal tread of the caterpillar can be deformed, which will affect its fit to the caterpillar and the protective effect. Rubber treads can also be deformed at high temperatures.

A decrease in anti-slip properties: patterns or irregularities on the surface of the rubber tread of the caterpillar can be smooth due to wear, which will lead to a decrease in anti-slip properties and an increase in the risk of an excavator slip during movement.

Preparation for installation

Preparation of tools: Prepare all the necessary tools, including wrenches of different specifications (for example, unitary and rocks), heads, screwdrivers, hammers (rubber or copper, so as not to damage the equipment), jacks and dynamometric keys (used for accurate control of bolts tightening force) .

Choosing a place: Select a flat, strong and spacious platform for ease of work. At the same time, make sure that there is enough space around the excavator to avoid the inconvenience and threats of safety caused by a narrow platform during installation.

Equipment checks: thoroughly check the excavator caterpillar, clean the surface of the caterpillar from dirt, sand, oil and other garbage, check if the caterpillar is damaged, whether it is deformed or has other abnormal conditions. If there is a problem, first repair or replace the appropriate details to make sure that the caterpillar is in the good condition of the installation.

Tread checking: thoroughly check whether the model and technical specifications of the caterpillar tread the excavator correspond to, and also check if the protector has quality defects, such as cracks, deformation, missing parts, etc., to make sure that the tread meets the quality requirements.

Stages of installation

Renovate the excavator: with the help of the jack, slowly lift the side of the excavator on which the protector must be installed, so that the caterpillar is cut off from the ground to a certain height (about 20-30 cm, the specific height is determined depending on the actual ease of use), and then put it under Solid blocks (for example, sleepers) to ensure the stability of the excavator and prevent it Moving or overturning during the installation process.

Placement of treads: Determine the exact place of installation of the traffic tread on the way in accordance with its design and installation instructions. For a fully closed path, start from one end of the way and level the edge of the tread with the edge of the road; For a segmented track, place each protective block in the way in the sequence in accordance with the pre -planned position.

Install the mounts: in a certain place of installation using a screwdriver or wrench, initially install bolts, nuts, clamps and other fasteners that fix the tread of the caterpillar, but do not tighten them completely to ensure the possibility of subsequent adjustment of the tread position.

Adjust the tread position: after the initial installation of the mounts, carefully check the landing of the tread on the caterpillar to make sure that the protector fit tightly to the caterpillar without obvious gaps or displacements. If necessary, you can slightly tap through the protector with a hammer in order to more accurately adjust its position; For some details requiring accurate adjustment, for example, the tread fitting to the leading and guiding wheels, you can use tools such as scraps to perform accurate adjustment.

Tighten the fasteners: making sure that the tread of the caterpillar is in the correct position, using the dynamometric key sequentially tighten all the mounts in accordance with the specified torque value to ensure a reliable installation of the caterpillar tread. Different types of excavators and tread of caterpillars can have different torque values ​​for their fasteners. Be sure to work strictly in accordance with the requirements of the operating manual.

Install the tread on the other hand (if any): if it is necessary to install tread caterpillars on both sides of the excavator, perform the above actions and perform the same installation operations on the caterpillar from the other side.

Checking and eliminating problems: after installing once again, check the correct installation of the tread of the caterpillar, including tightening fasteners, the density of the tread of the tread to the caterpillar, as well as the lack of interference between the tread and other components (for example, leading wheels, guiding wheels, asterisks, etc. .). Then run the excavator, slowly move the caterpillar and monitor the state of the tread of the caterpillar during work to make sure of its serviceable work without weakening, falling, abnormal wear, etc.
