Rigging Points Of Attachment - A Critical Element of Heavy Lift

cover-image Rigging Points In Heavy Lifts Are Critical
Review of rigging attachments to the equipment being lifted have prevented lift failures.  When planning major crane lifts we are very careful about confirming the crane foundation, rigging stability/capacity, and crane capacity. Are we taking enough time to analyze the points of attachment for the rigging? Becht Engineering Heavy Lift Division says “NO”. Our experience is that reviews of rigging points of attachment have identified critical flaws that may have resulted in dropped loads. In industry today, the load/vessel designers typically design the lifting lugs and trunnions at the same time. It is our experience that the owners of the equipment and the crane contractors are assuming these devices are properly designed and rated. It is a common practice that the crane contractor assumes responsibility for rigging above the points of attachment. Generally, the consensus is that trunnions and lift lugs are designed by others and they should be right. That...

Crane Mats of the Future – Timber, Composite or Steel

crane_mats_fig4
Where will crane mats be in 10 years, 20 years, 50 years? It takes approximately 90 years to grow a 12-inch by 12-inch oak timber twenty feet long. High quality hardwood timbers are becoming harder to find. This is widely known but rarely discussed. The shortage of wood timbers is a national problem. Timber Mats Crane mats have typically been constructed using oak or other select hardwood timbers.  In recent years, as supply dwindles, timbers do not measure a full 12-inch cross section. As they are milled, we often see one or more sides are not square but rounded due to the smaller diameter of the raw cut logs. In some cases, we are seeing timber mats made from mixed wood species, and some with combined hard and soft woods. Ground bearing pressure and load distribution calculations for timber mats are based on a full cross section of matched hardwood with...

Becht Dimensional Technology Mitigates Potential Problems In Heavy Lifts

dimensional_control_w_heavy_lift
Written by Joe Collins & Derek Paterson Safety and precision are of the utmost importance of any heavy lift operation. Heavy Lift Field Advisors are tasked with measuring clearances to assure the load will clear obstructions, a step often done by hand with a tape measure. Moreover, Field Advisors are also charged with assuring the location of the crane matches the plan. It is critical that the crane is on the precise radius for the capacity charts to be valid – too far away and the crane will not have sufficient capacity to handle the load; too close and crane can’t boom up high enough to place the load. Again, these verifications are often done by hand with tape measure. In this article, we talk about specific heavy lift problems that could have been avoided by integrating Dimensional Control with the projects. So - What can happen without precise measurement? Example...

Elements of a Super Heavy Lift Execution Manual

becht_heavy_lift_manual
Making A Super Heavy Lift?  Here's What You Need To Know If you are making a single super lift or a series of super lifts there will be a tremendous number of documents created during the planning stages.  In addition to the original documents there will be numerous revisions as the fine tuning of the details are realized.  The document control of the process can be overwhelming - but is critical for success.  Ultimately, there is a risk that the field crews may not possess the most current revision when they attempt the lift.  That omission could end in disaster.  There is no one definition for a "Super Lift" in any current standard.  However, many companies performing extreme lifts within their facilities have coined the term and created their own definitions.  The goal is to minimize risk by requiring a comprehensive engineered lift plan followed by a third-party review of the...
