A Guide to Pendant Hoist Cables in Heavy Industry

 

Pendant hoist cables are designed to be used with other crane cables in heavy industrial activities such as mining, quarrying, and building. Pendant Hoist control cables are intended to withstand severe mechanical loads such as torsion, torque, and tension.

Pendant Hoist Cable Specifications

Pendant cables are used for control applications, conveying signals to overhead cranes and gantries using push-button controllers. They are employed in overhead crane feeder applications because they provide flexibility and resilience across a wide temperature range of -15°C to +60°C for fixed installations.

The PVC-sheathed flexible copper pendant hoist cable has a voltage rating and galvanised steel wire rope that provides suspension support up to a maximum suspended height of 80m and a pulling force of steel core. They are multicore cables with 5 cores or more.

Why Would A Crane Operator Shorten A Pendant Cable?

When dealing with extra-long pendant cables, it's not commonplace for crane operators to pick up the slack, loop it, and fasten it with a zip tie as a quick and easy way to get the necessary cable length for operations. This way of shortening a pendant cable is known as a service loop. When completing crane inspections in the field, professionals frequently encounter service loops.

Another reason a crane operator may employ a service loop is to store additional slack for later usage in case cable segments or the pendant requires repair. The wires could ostensibly be cut at the cable's base and still have additional length to rejoin a repaired pendant control or at the top to remove sections of damaged cabling, if necessary. 

 


A pendant station is a set of switches that regulate the heavier electrical loads of cranes or hoists. These are also utilised in industrial facilities to regulate conveyor belts and product line equipment. Pendant stations are designed to facilitate lifting and handling applications. These devices may appear basic, but they contain various components such as switches, knobs, and push buttons to monitor the systems.

Pendant control stations are available in several series, including wall-mounted, direct control, and command and control machinery. They are divided into two types: push-button pendants and radio-control pendants.

The control box trolley serves as the first mobile carrier at the mobile end of a control festoon system. A mobile junction box or fast disconnect connection can be used to connect a push-button pendant to the control box. Pendants are typically supplied with fast disconnects. This allows for a smooth transition from radio control to the standard pendant.

Why Ravioli Slip Rings Outperform Traditional Designs

Image
  The ravioli slip ring is a flattened, round, disc-like shape that mimics the Italian pasta of the same name. This tiny design was developed to maximise space economy in settings where a standard tubular or capsule slip ring could be too bulky or heavy. It was not picked randomly. Another facet of their innovation is the use of materials that make slip rings easier to create. High-grade conduction metals, such as copper or silver alloys, for internal wiring, have been carefully selected for their superior gearbox performance. These are used with strong yet lightweight materials for the external shell, such as aluminium or various hardened plastics. The materials must be robust enough to withstand the demands of various working environments, hence increasing the slip rings' lifetime and durability. Ravioli slip rings differ from other types of slip rings because of a few distinguishing features. The most striking feature is its flat, tiny design, which has significant spac...

Proper Training For Crane Operatives Is Vital

If you are the owner of a business that uses overhead cranes, one of the most important factors is to ensure that your workplace is safe and secure for your employees, and for anyone else who may visit your factory from time to time. Overhead cranes are heavy and powerful machines that can be used to move heavy loads and materials, and therefore it is essential that you make certain that your employees are properly trained in their use. There are important things to understand, not the least of which is that overloading the crane can cause severe damage and can mean that the load could swing or drop. If something heavy is not properly secured and is dropped it can cause serious, or even fatal, injury. Another problem is that of a swinging load. If the operator fails to centre the hoist over the load, then when lifting begins, the load will swing towards its’ centre of gravity and could strike another employee.

Ravioli Batteries: An Innovative Concept with Promise

Ravioli batteries are a creative idea for a new type of battery architecture that resembles the pillowed shape of ravioli pasta pockets. While not edible, this unique layered design shows significant promise for improving various battery performance metrics. Batteries function as energy storage devices. They convert stored chemical energy into usable electrical energy. Fundamental components include: ●      Anode - the negative electrode that gives up electrons to the external circuit ●      Cathode - the positive electrode that accepts electrons from the external circuit ●      Electrolyte - the ionically conductive medium enabling flow between electrodes ●      Separator - an insulating barrier preventing direct electron flow   These batteries utilise reduction-oxidation (redox) reactions to generate electricity: ●      Oxidation at the anode produces electrons ...
