Designed by Airfloat®, air skates or air skid systems allow for the safe, nearly frictionless movement of large loads or machinery. They come in a variety of sizes and capacities and are lightweight and durable. These systems are designed to compete with systems and solutions that are far less flexible, including heavy duty casters and rollers.
Each new year offers LGH an exciting opportunity to grow and become a bolder company with the same traditional values. Our marching orders for many years have been to continue to open 2-3 rental center locations each fiscal year. The Parkinson family has invested so much into the LGH business and has provided the necessary resources to make the LGH goals and plans become true possibilities. With those efforts and resources, we now have grown to 21 locations nationwide. In fact, 2016 was the year we branched into Canada by opening our a rental center in Toronto, Ontario, which was a logical choice for us due to its booming industry. The same vision and courage that were required to expand into Canada will be needed once again as we begin a brand new year, which is abound with endless potential and opportunities for newfound growth.
Using slings at an angle can become deadly if that angle is not taken into consideration when selecting the sling to be used. The tension on each leg of the sling is increased as the angle of sling, from horizontal, decreases. It is most desirable for a sling to have a larger angle of lift, approaching 90-degrees. Lifts with angles of less than 30-degrees from horizontal are not recommended. If you can measure the angle of the sling, or the length and height of the sling as rigged, you can determine the properly rated sling for your lift. This may also be called a Tension Factor, but we will refer to this as our Load Angle Factor [L.A.F.].
Choosing equipment such as electric chain hoists for your project isn’t necessarily as simple as just point and order. There are many considerations to contemplate before you can place an order and a lot of them are going to be things your boss wants to know. To prepare you for that, we put together a guide to help answer some of the questions your boss might have when it comes to choosing your next electric chain hoists.
Your boss might ask…

Manufactured by Straightpoint, the compression load cell is a highly accurate device that is used to measure weight or force in a number of different applications. They can be used to measure compression, tension, bending or shear forces. Additionally, they can be used for a broad range of industries including steel fabrication, ship building, structural weighing, shipping and general transportation, to aid in calculating the total mass and center of gravity.

A greatly underused tool of wonderful convenience, turnbuckles have the ability to relieve you of a lot of stress during a challenging lift or rig. Primarily, turnbuckles are used when you need to increase or decrease tension in order to make minute adjustments to a load that are sometimes due to an off-set center of gravity. Turnbuckles can be used to make adjustments to help equalize the load and to correct that off-center of gravity. For example, if an individual needed to have 10-feet and 7 ½ inches of total running length, but didn’t have a sling of comparative length, this person could install a suitable turnbuckle to accommodate for the difference in sling length. The worker could simply adjust the turnbuckle in or out to get the desired length required for the lift. We recommend that when adjusting turnbuckles to use an appropriately-sized wrench instead of using a spud wrench of pry bar placed through the body. The latter tends to cause damage to the turnbuckle and could potentially create dangerous repercussions. Also, turnbuckles are rated for tension, so they can be used in any linear direction.
As you might’ve noticed, we refer to D/d Ratio quite a bit in some of our blogs and social media posts. However, there seems to be a bit of confusion regarding what D/d Ratio is and what purpose it serves. Hopefully, we can clear all of that up now.
The D/d Ratio has a tremendous impact and effect on sling capacity when using , and Chain Slings. The D/d is the ratio of the diameter (D) around the object which the sling is bent, then divided by the overall diameter (d) of the sling being used.
There’s been some confusion as to how to configure and use either system effectively without causing damage to the equipment, load, or to the user. Some of this confusion results from misunderstanding the difference between single-acting or double-acting cylinders and being unsure of when either should be used. Hopefully, we can clear the air in this department.
The Minifor™ hoist is a lightweight portable power hoist which can be used for a number of lightweight operations and they typically come in two models: the TR30 and TR50. Both are used for lifting light loads, which are usually less than approximately 1000 pounds, but by adding sheave blocks to your rigging scheme can increase the Minifor™ carrying capacity exponentially.
The advantages of using the Minifor™ is its portability, fast installation, pendant control, and ease-of-use nature. What makes them efficient is that both models use 1/4th inch cable, are powered with just 110 volts, and you can use an unlimited amount of wire rope and you can change it out yourself whether it be for different height requirements or if/when the wire rope begins to deteriorate. However, with its lightweight and portable design comes a bevy of ways to mishandle or misuse it and we’ve got the top 5 ways below.
