Rigging Services: Understanding Rigging Components For Cranes...

Posted by , on Nov, 2019

Rigging is not something those use cranes should ever ignore. It is a necessary component of such operations. Without it, the process may be far from smooth, and the operator’s safety is compromised. To make certain everything proceeds without issue, crane operators must work closely with reputable rigging services. Only they completely understand the basic components of the rigging system. Rigging and Cranes In order to be aware of how to best repair and maintain rigging, riggers must know about the different components involved in crane operations. Such knowledge must extend beyond recognition to encompass the requirements, specifications, and tools needed to address what each type of rigging demands. The following parts are of primary importance: Rigging Hooks: The specific types of hooks used in rigging must be able to lift, without slipping, heavy loads. They come in different sizes based on either the throat or hook. Selection depends on the materials the rig/crane must move. Based on what is a safe load-weight, the rigger selects the right size and decides whether the type is to be 1. Choker 2. Clevis grab 3. Eye 4. Sorting Shackles: Shackles are required when a load ranges between 6,000 and 11,000lbs. They are available in different sizes. Types include: 1. Screw pin 2. Round pin 3. Safety type anchor 4. Chain shackles Eye Bolts and Steel Nuts: Eyebolts and steel must work together to accommodate the designated load’s weight, shape, and specifications. Wire Ropes: These, in conjunction with slings, are responsible for moving large materials. Slings: Slings work in conjunction with wire ropes to move loads. Pulleys and Blocks: These are essential for extremely heavy loads. Available in diverse sizes, they generally work with wire rope to facilitate maneuvering the material Rigging Services Rigging is essential for certain industries. When specified for a job, it is important to hire only professional rigging services. This helps to ensure the work is performed correctly and safely. Be the first to...

Common Problems Steam Turbine Services Address

Posted by , on Dec, 2018

Steam turbines are rotating machines. They are engines electricity companies use to produce power. However, as is the case with all types of machinery, it can suffer from a variety of problems. Companies supplying steam turbine services are available to address many of them, including the most common types. Common Problems Affecting Steam Turbines It is critical to keep steam turbines in a power plant operating efficiently, effectively and on demand. Failure to do so has serious consequences. The most common problems, some resulting in repair work, retrofitting or complete replacements affect specific parts or are the result of existing conditions. Two common affected parts are 1. Rotors: Bending causes steam turbine blades to fail. It can also negatively affect the ability of other components to operate properly. General causes are a. Rubbing in the diaphragms or labyrinths b. Rotor or casing misalignment 2. Bearings: Turbine bearing failure results from its severe operating conditions including: a. High temperatures b. Moisture-laden setting c. High transient thrust loads d. Long time spent in idle readiness – This condition results in the highest level of exposure to corruptive contaminants All of the above can result in increased rotor vibration. This severely affects the ability of the steam turbine engine to function efficiently and effectively. Steam turbine services include maintenance programs designed to prevent such issues. By adopting preventive measures, hydroelectric companies can reduce the instances of steam turbine failure and power production interruption. Steam Turbine Services Steam turbines, in spite of the increased use of combustion turbines, continue to provide the power for the production of hydroelectricity. Even with the current improvement in steam turbine technology and the means of addressing their potential problems, certain issues affecting efficiency and operation shall continue to exist. It is up to the company to ensure they hire a company capable of supplying the level of steam turbine services their equipment needs. 2 people like this post. Like...
