Crane outrigger pads are made from a high-quality polyethylene. This means they will not splinter, crack, are non-conductive and will not absorb water. They are easy to install and provide a safe working environment for heavy equipment with outrigger arms.UHMW Plastic crane outrigger pads are used under the support legs of heavy cranes, crawler cranes, boom pumps, concrete pumps, fire trucks, utility trucks, tree trimmers, any type of aerial equipment, etc. Make the machine work safely!
Product advantages:
1. The surface of the special outrigger pad is smooth to ensure the safe use of people and cranes.
2. Good wear resistance, impact resistance, and longer service life than steel pads and wooden pads.
3. Lower density and lighter weight than other materials, easy to use and move
4. Excellent compressive performance can avoid ground damage caused by heavy load. Compression loads up to one million pounds. Up to 15,000 pounds per square foot
5. Good self-cleaning, temperature range: - 150°C to 85°
6. Low water absorption, will not change due to changes in humid environment.
7. The wear resistance ranks first in plastics, 4 times higher than nylon 66 and PTFE, and 6 times higher than carbon steel;
8. The impact strength ranks first among plastics, which is 2 times that of PC and 5 times that of ABS, and can maintain high toughness at liquid nitrogen temperature (-196 ℃);
9. The self-lubricating property is equivalent to that of PTFE, and the friction coefficient is only 0.07-0.11;
10. The shock energy absorption value is high among all plastics, and the noise reduction effect is very good;
11. It has high chemical stability and can resist various corrosive media and media within a certain temperature and concentration range;
12. Strong anti-adhesion ability, second only to PTFE;
13. Completely hygienic and non-toxic, and can be used to contact food and medicine;
14. Excellent corrosion resistance, low friction coefficient, small specific gravity, and good resistance to high-energy radiation. Ultra-high molecular weight polyethylene is chemically stable, and can be corroded by various corrosive media and solvents such as acid, alkali, salt and so on within a certain temperature and concentration range;
15. When the molecular weight of HDPE exceeds 500,000, the embrittlement temperature drops to 140℃. Even under the action of liquid nitrogen, the ultra-high molecular weight polyethylene can be used at a temperature below 269 °C, and still has a certain mechanical strength.

Apr 15, 2017 · Material: Should be better than the material of Sub Grade. The Upper Base urse is made up of sand, gravel, and stone. The Lower Base urse is made up of cheaply available material i-e rock and stone fragments. 3. Road Base: Due to quality of material used in the road base it is divided into. Upper Road Base.
Sep 17, 2019 · However, there is no need to panic because here is what you need to know about the materials used for road nstruction. Asphalt. First on the list is Asphalt. This material is petroleum in a viscous liquid or semi-solid form. When it is used for pavements and road nstruction it mes in the form of a mposite material, asphalt ncrete.
The objectives of this program can be summarized in the following main points: Enhancing the skills of road nstruction engineers in their field. Introduction to road nstruction materials. Determination of engineering properties of road materials. Quality ntrol and quality assurance in road nstruction.
They also reduce the size and change the form of waste materials. Impact crushers involve the use of impact rather than pressure to crush material. Motor grader. A grader is mm used in the nstruction and maintenance of dirt and gravel roads. In the nstruction of paved roads, they are used to prepare the base for placing the asphalt.
Answer (1 of 24): The road trails are made by applying gravel and other llective materials to create a travel-able surface. For areas with more traffic, a better choice may be a chip, tar, or bituminous surface healing road, where llective nstruction materials are mixed with clammy binders
Classification of Roads and their Details [PDF] Road transportation is an essential network for any untry. This ale discusses the classification of roads based on many factors, such as materials, locations, and traffic. 1. Earthen Roads. 2. Gravel Roads. 3. Murrum Roads.
Types of Building Materials. The following is the different types of building materials list used for nstruction, 1. Mud and Clay. Mud is defined as the mixture of soil, loam, silt, or clay with water.
Oct 30, 2019 · In order to press asphalt, soil and other loose materials, drum rollers are used. This machine is typically found at road nstruction sites. There are two types of drum rollers: smooth rollers and padfoot rollers. Smooth rollers provide static pressure and use vibration to mpact loose materials.
