Frequently here at Kenco we are requested by a customer to provide a below the hook lifting device based solely on the dimensions (height, width, depth) of the object being lifted. While these parameters are likely the most pertinent, there are a host of other factors necessary to take into consideration in order for our engineers to provide the best solution.
Second only to dimensionality, is the material and structure of the object being lifted. If the object lacks the structural integrity to tolerate a pressure grip type of lift, it is necessary to determine what aspects of the object can be exploited to perform an alternate lift operation. Example: Does pipe need temporary bracing (stulling) to prevent crushing?
The amount of clearance available for the lifting operation is also an oft-overlooked factor. All aspects of the device’s intended use should be considered, including but not limited to:
– Distances between the object to be lifted and adjacent objects
– in storage
– in transit
– in staging
– at final placement
– allowable overhead clearances
– any changes in the orientation of the object that need to take place during the operation (such as from laying flat to standing upright position).
Another major factor in choosing the right Kenco lifting devices for heavy objects is the type of equipment to be employed in both the handling and transit operations. Excavator attachments, forklift adapters, cranes, etc.. all have different operational characteristics that affect the handling of the object.
