An optional auger system can be mounted to either the boom base section or to the second stage of the boom for variable radius drilling up to 54 feet (16.46 metres) at any position through the 360 degree rotation of the crane. Even though the outriggers were out, the weight of the load caused the crane to overturn. Two types of commonly used cranes, a crawler lattice boom crane and a hydraulic rough terrain crane, were selected as examples in developing these guidelines. The reasons are many and can only be briefly mentioned here. The number of supervisors who know little or nothing about cranes is shocking. Also, some cranes are not maintained properly nor inspected regularly to ensure safe operation. The knowledge of the length of boom and radius in determining capacity. Manitowoc says the new model has many of the same features as the original MLC300, just without the variable position counterweight (VPC). It has been demonstrated that there is a tendency for some operators to become overly reliant on the devices and to use them in place of judgment. There are markets that will appreciate the increased capacity with these transport weight options, says Link-Belt product manager for lattice and telescopic crawler cranes, Scott Knight. Studies and analyses often show they are frequently due to a lack of preventive maintenance or adequate training and/or experience on the part of the personnel involved.
