Boom Deflection: What You Need to Know

on .

Boom deflection is a phenomenon that occurs when a crane is lifting a load and its boom appears to be bending. All booms have this ability to flex so that they can absorb the loading forces that come from lifting a heavy weight.

Boom deflection happens to all cranes, both hydraulic and lattice boom. Even though it’s a normal result of lifting, there still must be safety precautions and awareness. Let’s go over what you need to be aware of for boom deflection during your lifts:

Every crane has a specified safe working load defined in the load chart. As a general safety guideline, be sure to check each crane’s load capacity before any operation begins.

Should you rent an All-Terrain Crane or a Crawler Crane? - Crane Rental Podcast Episode 8 - 4K

on .

We got a question sent to us on our Instagram account [CraneServiceInc] asking why would you rent an all-terrain crane vs a crawler crane. This was a great question because it involves a few factors and schools of thought. In our example we throw out the price of the all-terrain crane and the price of a crawler crane. Technically that does matter, but you will see why I throw that factor out during this article. I will briefly talk about the differences and advantages of each crane class. In this article we will talk about the Terex AC250–1 versus the Manitowoc 2250. Both of these cranes are 300 ton class cranes.

Ground Pressure and Proper Matting

Article written for and published by Crane Rental Hotline - Feb. 2016.

There are many factors that go into a successful crane lift and/or project that involves a crane. These factors range from weather, having the proper equipment, training, to site preparation. In this sidebar we will focus on the later, site preparation. More specifically ground bearing pressure and proper matting and how it relates to cranes.

In the crane industry we rely heavily [no pun intended] on the ground below us to support our large machinery. So let’s talk ground pressure. We need to start by defining a few terms. The bearing capacity of soil, in its simplest form is the pressure the supporting soil can support before the soil fails. The ground pressure is the amount of force the object(s), in our case outriggers, are placing on the supporting soil. The crane and machinery can transmit extreme forces through the outriggers or through the tire contact patch onto the supporting foundation. If the ground bearing pressure exceeds the bearing capacity of the ground, you will have an issue, usually in the form of a failure in the supporting soil.
