Lifts that require machinery or assemblies furnished by others.

Lifts that involve turning or flipping the load, which can result in “shock loading” or “side loading”.

Lifts in congested areas where structures, pipelines, power lines or other obstacles are located.Other examples of critical lifts include the following: The first step in establishing a corporate mobile crane lift-planning requirement is to define the term “critical lift.” According to the Construction Safety Association of Ontario, a critical lift is one where the load weight is heavier than 75 percent of the rated capacity (Campbell and Dickie, 227). However, critical lifts require more extensive planning and oversight by qualified persons. Even noncritical lifts require knowledge of the weight of the load (and other components considered to be part of the load), the configuration of the crane, the rated capacity of the crane at its lift configuration, and factors that may affect the crane’s rated capacity in order to make a “go/no-go” decision. Therefore, establishing criteria for “critical lifts,” preparing formal lift plans, understanding the factors that affect rated capacities of mobile cranes, ensuring equipment is in good condition, and ensuring only qualified and trained personnel operate the equipment are all important components in preventing mobile crane incidents.Īll crane lifts require some level of planning, whether the load is a mere half-ton or more than 2,000 tons. Edit your jobsites in a two-dimensional drag-and-drop environment allowing you to create more complicated lift plans in less time.“People do not plan to fail, they fail to plan.” As a result, less-than-adequate crane lift planning encompasses most, if not all, of the above causal factor categories.Import CAD drawings, Google Earth images, or any picture to accurately depict your lift.Easy to create detailed 3D jobsites and rigging designs.Highly accurate graphics are in true 3D, allowing you to view the lift plan from any angle.Provides several filter options so you can search only the cranes and configurations you choose.

Accounts for any obstruction in your jobsite whether it’s to the side, front, rear or above the crane.

Displays the most economical crane configurations that can handle your lift at the top of the results list, allowing you to save time sifting though charts or a long list of possible choices.

Searches your entire fleet of cranes in seconds.

Automatically calculates Crawler Loads and Outrigger Loads, as well as ground bearing pressure below crane mats.

Allows you to view the load chart to see the capacity at various boom lengths and radii.

Change boom angle, jib length and offset, load location, and lift radius and 3D Lift Plan will automatically update your chart.

Performs simulation of your lift while monitoring the crane’s capacity.
