XCMJ shows off massive 2,000-ton crawler crane

by Leave a Comment

XCMG has been showcasing the power of its new, massive crane.

XCMG’s 2,000-ton XLC26000 crawler crane has successfully completed the hoisting and installation of a 603-ton carbon dioxide stripping tower for the construction project of the largest green fertilizer plant in Bangladesh in this month.

The XLC26000 is the largest ever tonnage crawler crane that China has exported to Bangladesh. Bangladesh has been relying on importing agricultural fertilizers. [Read more…] about XCMJ shows off massive 2,000-ton crawler crane

DFI’s Bridge Crane solution provides one-off customization and worry-free management

Industrial computing specialist DFI has unveiled its Bridge Crane solution, which it says provides one-off customization and worry-free management

An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of parallel runways with a traveling bridge spanning the gap.

A hoist, the lifting component of the crane, travels along the bridge. Every year in the modern ports of the world, tens of thousands of containers and bulk goods come in and out through bridge cranes.

Unlike mobile or construction cranes, overhead cranes are typically used for either manufacturing or maintenance applications, where efficiency or downtime are critical factors. [Read more…] about DFI’s Bridge Crane solution provides one-off customization and worry-free management

Construction: Interference could undermine development of crane technology

Keith Armstrong, worldwide electromagnetic compatibility specialist at EMC Standards, looks at problems with electrical interference and how construction managers can minimise their risk

Cranes are synonymous with the idea of development. Typically used to construct buildings, cranes aid the economic and social development of a town or city. However, cranes suffer from a persistent problem that is indicative of a significant threat to the future of technology: interference.

In the early days of the UK Department of Trade and Industry’s EMC Awareness Campaign, there was an infamous incident where a man was crushed to death by a crane. In this case, electrical interference caused the crane to prematurely release its load while the man was operating it with his radio-control pendant. Unfortunately, this tragedy is not an isolated incident.

There was another incident with a company that claimed to have made the controls and drives for the first large scale hovercraft-testing tank in the late 1960s. It was, in effect, a sophisticated travelling overhead crane, which ran the length of a gantry along overhead rails and towed a hovercraft shape along a large pool of water in an even larger building. In those days, they used resistor-transistor logic, which ran on a 40 V rail to provide noise immunity.

crane at the DB Port Szczecin container terminal

Measuring over 100m wide and over 60m high and with a lifting capacity of 45t, the port crane used for loading and unloading containers is one of the many items of equipment that have been modernised during the current year by Apator Control engineers.

The crane at the DB Port Szczecin container terminal has undergone a thorough electrical and mechanical refit.

As part of the electrical overhaul, Apator Control used systems from the company Control Techniques: Unidrive M AC and Mentor MP DC drives controlled by the Simatic S7 Programmable Logic Controller (PLC).  [Read more…] about Emerson drives streamline port crane application
