Moving a mobile crane: travel configuration, axle loads and assembly

Identify the exact crane model and travel configuration, gross and axle weights, dimensions, fitted equipment and separately transported parts. Then check the proposed route and applicable vehicle, road and permit conditions. Nominal lifting class does not supply those transport inputs, and another crane’s familiar arrangement cannot establish what the actual carrier may retain while traveling or how its loads are distributed.

The Grove GMK3060L-1 page lists 60 t nominal capacity and 36,000 kg total gross vehicle weight as different specifications. The lifting figure is not a tare or travel weight, and the gross-weight entry does not establish every optioned or modified configuration. Keep the actual crane identity and equipment basis with the road-weight evidence rather than using its capacity class as a scale reading.

Grove lists 13.5 t total counterweight, with 7.5 t within a 12 t/axle configuration and 13.5 t within a 16.5 t/axle configuration. Preserve each arrangement and its conditions rather than assuming the entire counterweight always travels under the lower axle figure. These published configurations do not approve a US road movement or replace the actual axle schedule and responsible authority’s requirements.

An expressly even division gives 12,000 kg per axle, but a total divided by axle count is an average rather than a measurement of each axle. The actual equipment arrangement can change distribution. Obtain the applicable travel information and relevant loaded axle weights instead of using that average to establish every axle, tire, bridge-group or route condition of the crane being moved.

A 2.55 m minimum width converts to about 100.4 inches, below the 102-inch National Network reference in 23 CFR 658.15. This is a dimensional comparison, not proof of the actual configured width or route permission. The fitted equipment, rule scope, other dimensions, axle loads and any applicable special-mobile-equipment or permit provisions still require their own assessment.

Record the actual counterweight, boom or jib arrangement, hook and other equipment, tires and any optional travel-related components. Identify which items remain fitted under the manufacturer’s permitted arrangement and which are transported elsewhere. A total-counterweight specification does not establish that all of it can remain on every road configuration, and a removed item still creates a load on the vehicle carrying it.

Establish each component’s actual weight, dimensions, approved lifting and support requirements and securement arrangement, then assess the carrying vehicle and load distribution. The crane carrier’s permit or ratings cannot approve a separate trailer. Include the loading and unloading arrangements at both sites rather than treating counterweight or boom components as an unmeasured accessory load outside the transport plan.

A route that reaches the entrance does not establish turning space, support, clearances or an adequate area for the required assembly and component handling. Check the actual collection and delivery conditions alongside the travel arrangement. The permitted configuration must be achievable at each end under the applicable procedure; removing equipment for the road can create additional space, support and handling requirements at the site.

Within its construction-crane scope, OSHA 1926.1404 requires an A/D director meeting its competent/qualified-person criteria, or its specified competent person assisted by qualified persons arrangement. When only one person performs the operation, that person must meet both criteria. The transport driver’s role alone does not establish the required qualification or authorize an improvised assembly sequence.

Use the applicable manufacturer and regulatory procedures for ground support, blocking, component capacity and the actual assembly sequence. A permit for travel cannot establish those site conditions, and a product-guide drawing cannot supply an unapproved method for removing counterweight or boom equipment. Plan the people and equipment needed for the actual operation rather than assuming a self-propelled crane requires no controlled handling at either end.

Self-propelled travel is a configuration and regulatory-category question, not a blanket exemption from every road or permit requirement. Establish the applicable treatment for the actual crane and jurisdiction, including axle loads, dimensions and the proposed route. A general special-mobile-equipment provision cannot be assumed to waive all state, bridge, registration or operating conditions for an unidentified road movement.

A lifting chart addresses its stated operating configuration and load position rather than certifying road weights and clearances. Keep the actual travel information, axle schedule and fitted equipment with the transport assessment. Conversely, a crane that meets a travel arrangement is not automatically set up for a lift; support conditions, operating configuration and the applicable chart have to be established at the work site.

Keep the crane identity and travel configuration, actual dimensions and axle information, component inventory, support-vehicle loads, route authority and site handling requirements together. Confirm any changes before movement rather than relying on a previous job’s arrangement. That record distinguishes lifting capacity from road weight and follows each removed component through transport, unloading and the required assembly process.
