Although this is a topic that many of our customers are familiar with, the proper use and care of hydraulic lock nut rams is something that still causes some confusion on the job sites where they’re used.
New API Guidelines for Production Hoisting and Drilling Equipment.
The American Petroleum Institute (API) just published its Publications Programs and Services catalog, an all-inclusive resource for all API practices and standards, equipment specifications and technical documents. It also contains studies and reports regarding the efficiency, responsibilities and safety of the petroleum industry.
Wire rope is a machine.
It’s a rather complex machine, actually. Its primary function is to move, which in turn is where it obtains its source of strength. And because it is such a complex piece of machinery, no precise rules have been given to determine exactly when a wire rope sling has passed it’s service or expiration date. There are guidelines, though, one should follow to know whether the sling they possess is suitable for continued use or needs replacement.
In 1960, when ANSI first published the B18.15 standard on forged eyebolts, they stated “that it would be impossible to develop an ANSI standard which would agree with even a small percentage of the standard products (eyebolts) being produced.” This forced them to attempt to come as close as possible to an average value for forged eyebolts.
While everyone is going around discussing how awesome sliced bread is (as if we didn’t already know that), another invention had already been registered at the patent office before sliced bread was even a thing. It’s a handy piece of equipment called the Tirfor®.
Also referred to as the Griphoist® or a German come-a-long, the Tirfor® is a registered trademark of the Tractel® Group, which was founded in 1941. It’s a pulling and lifting device that operates in conjunction with wire rope that passes through the machine. The device is controlled by two pairs of jaws that operate alternatively to drive levers, which allow the movement of the wire rope or cable for almost unlimited pulling length or lifting height with pinpoint accuracy in positioning loads. So yes, it’s awesome, but what exactly is the point of origin of it’s awesomeness?
With large complex lifts – using a planned tag line procedure makes the lift go very smoothly without anybody getting nervous or upset. One person should be able to control the complete tag line operation by just using hand signals to direct the other tag line tenders and in doing so will be able to maintain about the same tension on each tag line.
Tag lines can help keep a load under control – but remember, your weight is no match against a load that has started to swing and develop momentum!
Here at Lifting Gear Hire, we strive to put safety first and we encourage everyone to do the same. To do that, we endeavor to provide the most up-to-date knowledge and safety info to ensure a safe, successful lift every time.
Whenever any sling is used, its highly advisable to observe and follow a few basic safety practices. Henceforth, these are the 12 Sling Commandments that everyone should follow (if you want a safe lift, of course).
We’re glad you endeavored to ask. Discovered by the ancient Greek mathematician, Pythagoras, during 569-475 BC, the Pythagoras’ Theorem, also referred to as the Pythagorean Theorem, is a fundamental relation in the study of Geometry among the three sides of a right triangle (as pictured).
Although its commonly debated that the formula existed before his time, Pythagoras is well-assumed and credited with its first recorded proof. Since then, the theorem has been proven numerous times by various mathematicians including Euclid and Einstein.
According to the Associated General Contractors of America, the cost of materials and services used in construction rose faster than the price of completed buildings. Officials from the association have warned that the price of infrastructure could rise from the use of imported materials. With values dropping, purchasing equipment via auction or second hand is becoming more attractive to consumers to offset the rising costs in materials. However, one should exercise caution when it comes to purchasing any equipment from such venues as it does pose risks for your workers and for your budget and could potentially increase your exposure to harm. Rental companies do not sell used equipment because of this liability. There are also no Lemon Laws to help protect those who buy faulty/used equipment from an auction or otherwise.
