Rope guide for wire rope electric hoist

Rope guide for wire rope electric hoist

GB6067-1985 "Safety Regulations for Hoisting Machinery" requires that the outline ropes should be neatly arranged on the drum in order. The rope guide as a rope arranging device, which is defined as a device that enables the steel wire rope to be neatly wound around the drum at a prescribed interval. If no rope guide, the steel wire rope will be squeezed and deformed into the gap at the end of the drum; the oblique lifting will cause the random rope, the deformation of the steel wire rope, and the wear between the steel wire rope and the drum shell.The rope guides themselves can ...

Application of cranes in logistics

Application of cranes in logistics

The logistics industry has grown rapidly, and the demand for crane lifting equipment, which is one of the main logistics equipment, has also increased rapidly. Lifting equipment has been widely used in transportation, warehousing, distribution, and handling.In the past, the handling of goods in the logistics industry was mainly manual and semi-mechanized, and the work efficiency was not high. As the industry's mechanization and informationization level continued to increase, such as gantry, bridge cranes, jib cranes and other applications in the logistics and warehousing are continuously e ...

Crane wire rope and ground anchor

Crane wire rope and ground anchor

1. Crane machines (single beam cranes, electric hoist cranes) should be scrapped when the number of broken wires exceed 10%, the rope is rusted or the surface is worn up to 40%, and there are dead bends and structural deformation of the rope core. If the broken wire or abrasion is less than the scrap standard, the bearing capacity should be reduced proportionally, when it is manually driven, K = 4.5; when it is mechanically driven, K = 5 ～ 6.2. Wire ropes of crane machines should be with a safety factor of K = 3.5, specifications should conform to the requirements of the construction plan ...

Gantry cranes works in the rainy days

Gantry cranes works in the rainy days

In the process of modern industrial construction, the realization of mechanization has been popularized, although the crane machine has been carefully designed, in the application process, the outdoor gantry crane will encounter some unexpected situations, such as the rainy which will affect the work.Gantry cranes are generally used outdoors, so it is easy to slip due to rain. In order to avoid the crane safety accidents, the first thing to do is to start with the wheels of the crane, such as increase the friction between the wheels and the track, clean the track, etc.For safety, outdoor gantr ...
