Spring is upon us and the short break from road work is officially over. Along with the warmer weather comes the need for repair to roads and, more specifically, bridges that have taken a beating over the potentially harsh winter weather.
We’ve seen an increase in the number of come-a-longs, sometimes referred to as a lever hoist, that have been going out on rent lately, so this seemed like an appropriate time to detail some of the common misuses of this versatile piece of equipment as well as an easy solution to prolong their lifespan.
In this industry, the gear used to perform the lifts and moves on sites can have a tremendous impact on the result of any job. improperly maintained equipment or having the wrong gear for the job can stop a job in its tracks in a best-case scenario or even lead to costly or deadly accidents on the job. When it comes to the gear being used, there are some that believe owning their own equipment is the best way to go but, in many cases, this is not true.
Gantry cranes are portable, lightweight, and affordable lifting solutions with sturdy A-frame design. Gantries have many great features such as height adjustment, span adjustment and the heavy-duty casters. As with any good thing there comes the possibility of misuse. Below are five of the most common misuses to avoid.

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!
