Produced by Terex, the American HC 50 is a hydraulic crawler crane that’s nimble, yet, very capable of performing tough tasks. It has a 50 ton (45.4 t) max lift capacity, 160 ft. (48.8m) max lift crane boom length, and a 130+40 ft….Crawler Crane Information.

Typical lifting capacities are between 12 and 20 metric tons, with the record held by the K10000, made by the Danish firm Krøll Cranes. It can lift up to 120 metric tons at the maximum radius of 100 meters.
Ancient cranes represent impressive engineering feats given the technology of the time. However, the weight capacity of those early cranes is completely overwhelmed by the working load limits of today’s biggest cranes, the largest of which is capable of lifting 44 million pounds.

In terms of actual weight, the heaviest object ever directly weighed, according to Guinness World Records, is the revolving service structure of the launch pad at the Kennedy Space Center in Florida, clocking in at 4.86 million pounds.
Lead is probably the cheapest and most readily available of denser metals. It’s available for sale in stores worldwide for use in everything from plumbing and electrical work, to fishing tackle.

(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
Magnesium is extremely light: it is 75% lighter than steel, 50% lighter than titanium, and 33% lighter than aluminium. It has the highest known damping capacity of any structural metal, capable of withstanding 10x more than aluminium, titanium, or steel.
Iron and Steel, aluminum, Copper, Zinc, Lead, Cadmium, Manganese, and Magnesium are some of the cheapest metals found. aluminum is the most abundant metal on the planet. It is a bit costly to get it in pure form.

At one extreme, a rubber band is an example of a material with low stiffness—it can withstand a lot of deformation and still return to its original dimensions when the load is removed. On the other hand, a high-stiffness material like diamond will elastically deform only a small amount when load is applied.
In its two-dimensional form, graphene is thought to be the strongest of all known materials.
Modulus of elasticity (or also referred to as Young’s modulus) is the ratio of stress to strain in elastic range of deformation. For typical metals, modulus of elasticity is in the range between 45 GPa (6.5 x 106 psi) to 407 GPa (59 x 106 psi). If the Young modulus of metal is greater, it’s stiffer.
High-alumina ceramic has the highest specific modulus, the metals appear to have a higher specific modulus than the polymers and the polymers have the lowest specific modulus values of the three groups.
Increasing the stiffness or rigidity of a structural element reduces its deflection under load. This can be done by strengthening its section or increasing its size, but this will generally also increase its cost.
Weight Differences in Steel and Aluminum Steel is strong and less likely to warp, deform or bend underweight, force or heat. Steel is typically 2.5 times denser than aluminum.
The compressive strength of concrete is more than the steel, to handle tension forces steel bars are used in the concrete because of the weakness of concrete. The wall made of concrete alone is much stronger than the mass of steel. The strength of the weight of steel is higher than other construction materials.
