Posted by in Rigging

Plate lifting clamps lift and move plates and/or fabrications from one spot to another. The plates are generally composed of some form of steel; the lifters of alloy steel and other forged alloy components to ensure they are strong enough to handle the load. The directions the clamps can move the plates are one of two – horizontal or vertical. This depends upon the specific type of plate. Vertical Lifting Clamps When lifting and transferring plates, sheet or fabrications vertically, this is the type of plate lifting clamp an operator will choose for the job. It can also move and turn from horizontal to vertical and down again to horizontal if required to do so. The different types of vertical plate lifting clamps include: Standard clamp: For those materials that possess a surface hardness of up to 37Rc (345 HB) Larger jaw opening: For use with stainless steel material and those having a surface hardness of a maximum of 47Rc (450 HB) Vertical clamps may also be non-marring. As the name indicates, these will not scratch the surface material of the items they carry. Operators use them to carry such materials as: Aircraft skins Aluminum Composite material Glass Painted materials Plastic Stainless steel Vertical clamps allow you to lift all these items straight up with ease. Horizontal Lifting Clamps Horizontal lifting clamps may or may not have spring-loaded tension. While the former makes it easier for them to do so, a lack of this does not prevent them from transferring both sagging and non-sagging material horizontally. As in the case of vertical lifting clamps, you can purchase non-marring types. Plate Lifting Clamps Plate lifting clamps are helpful when it is essential to move material. The type you select will depend on the direction you need to transport the goods. With both horizontal and vertical options available, it becomes an easy matter to make a decision. Some shops will elect to install both. Be the first to...

The statistics are alarming. In 2013, more than 36 percent of all work-related fatal incidents involved falls from heights. According to the Occupational Safety and Health Administration (OSHA) working at high elevations not only demands the wearing of such safety devices as the fall protection harness, it is a legal requirement. Nevertheless, employees and employers continue to ignore the dangerous risk of not complying. The 20th Century In the late 19th and early 20th centuries, harnesses were not compulsory. In fact, construction workers on buildings, bridges and other structures did so without any form of protection at all. It was not until an adaptation of the telephone linemen’s body belts that they received their first protective device. In the 1920s and 1930s, few workers used them. The belts, while better than no protection at all, could be pulled off during a fall or cause serious spinal damages. In order for the belt to be effective, the worker had to fall properly. By the 1940s, those in the manufacturing sector had begun to produce a safety harness that was more suitable for use. Based on the harnesses employed by military paratroopers, it was able to better able to handle the fall arrest forces weight forces, reducing physical damage. However, this new fall protection harness was awkward to put on and made from cumbersome material such as leather and cotton. Overall, many workers avoided wearing them because they were too heavy and uncomfortable. During the period following the first step in the evolution of safety harnesses, companies received sufficient feedback from users. They took this and began to produce more practical and functional equipment. As the need for industrial safety equipment met the forces of the government safety regulations, significant changes began to take place in the design and manufacturing process or safety equipment. Form this were to arise different styles. Among them were two easy to use harnesses: Triangular style harnesses X-fit style harnesses Companies began to look to recreation harnesses for design inspiration. The...

Technology has advanced so much in the last hundred years and now, we have equipment that keeps us safer and makes everything a lot easier than ever before. Our buildings and other structures reach higher into the sky. While this means that more jobs requiring the workers to spend long periods of time suspended above the ground, it also means that safety equipment has become more advanced, secure and reliable. A self retracting lifeline is one such item that has saved the lives of many workers. What Is A Self Retracting Lifeline? There are several jobs that require workers to be suspended above the ground. The one that probably first comes to mind is the construction or repair of bridges, skyscrapers, roller coasters and any other tall structure. A fall from such a height would lead to serious injuries or even fatalities. When a worker suffers a serious injury from a fall, he or she will be unable to work for a long period of time, which is sure to lead to problems. A self retracting life line is a safety feature that is used to prevent this from happening. If the wearer of the self retracting lifeline happens to slip, the life line will use a brake to stop the fall. The design of the self retracting life line or SRL, will distribute the shock from the force of the fall across the body, which prevents discomfort and minor injuries. This is because of the straps on your harness, which the life line will be attached to by the back D ring. After the self retracting lifeline has jerked you to a stop, it will not let out any more rope. You can get back to where you were or wait for help, depending on the situation and location. Where To Find A Suitable Self Retracting Lifeline Because it is supposed to stop people from falling, a self retracting lifeline needs to meet the standards of certain safety procedures.
