Spider Crane Crawler With the development of modern production and capital construction, the position of hoisting machinery becomes more and more important. Construction sites, railway hubs, industrial and mining enterprises, from large iron and steel enterprises to busy ports, there are hoisting machinery everywhere, which undertakes the tasks of material handling and equipment installation of thousands of tons. With the expansion of domestic production and construction scale and the continuous improvement of automation and mechanization, the use of cranes is more and more common. As the latest scientific and technological product in the new era, the new spider crane avoids the complex transportation problems of ordinary hydraulic crane. It can not only walk freely on the construction site, but also enter the indoor and narrow space for hoisting operation, making the construction more convenient. Spider crane is suitable for large-scale material storage, large-scale production and manufacturing industries. It adopts wireless remote control or body switch for operation. It has fast operation speed, micro design, small volume and strong lifting capacity. It bid farewell to the era when it can only rely on human work in narrow space, which not only improves work efficiency but also ensures work safety. Spider crane is also called crane spider, micro crawler crane, small crawler crane, mini crawler crane, crawler spider crane, narrow spare use spider crane, mini spider crane, spider crane hire, mobile crawler crane, intelligent remote control micro crawler spider crane, etc. It is a full swing, boom type and full hydraulic transmission crane. The main boom is divided into 4-5 sections. The section of the main boom adopts U-shaped structure. The single-stage telescopic oil cylinder and steel wire rope telescopic mechanism can realize the synchronous expansion and contraction of the main boom. The boom expansion limit adopts double insurance of marking line and alarm, and the crane is equipped with radiator, which is conducive to high temperature work in summer. Forklift Wheel Loader Heavy fork loader is a new product in recent years. It is mainly used in mines, especially in quarries, to pry, transport, stack, load and unload massive stone blocks. Before the formal forklift was launched, people used mast cranes, truck cranes, excavators, forklifts and loaders (to replace forklift accessories) to load and unload mining stones or hoist stone blocks. Although these machines have certain operating performance and cost advantages, they have their own disadvantages. They are not as good as heavy fork loader in terms of applicability, cost and safety. Fork loading technology originates from the common shovel transport machinery - tire loader, which belongs to the variant product of loader. However, based on the loader, it has its own unique characteristics, which puts forward higher requirements for the boom lifting force, machine traction (climbing capacity), tipping load, steering and braking capacity of the machine. The heavy-duty forklift integrates the technology of loader and forklift, and overcomes the shortcomings of traditional forklift in lifting force, driving force, shovel loading performance, off-road performance and braking performance, as well as the disadvantages of insufficient lifting capacity and mechanical efficiency of loader. It has the off-road performance necessary for specific working conditions of stone and strong forklift loading capacity and flexibility, Won the favor of the majority of stone mine users.
