Pick and Carry Cranes

What happened?

Pick & carry cranes (commonly referred to as Franna cranes) are widely used in coal mines, however, they have been involved in several concerning incidents involving rollovers, loads falling, mechanical failures as well as uncontrolled movements and collisions. The Crane Industry Council of Australia estimates articulated pick & carry cranes currently account for somewhere between 64% - 68% of all crane incidents.

In the year to date (YTD) more than ten high potential incidents including five rollovers involving pick & carry cranes have been reported to the Coal Mines Inspectorate.

Incident 1

On 18 July 2021, a pick & carry crane was unloading an elevated work platform (EWP) from a flat tray truck. As the operator moved the crane to place the EWP on the ground, the left-hand wheels of the crane rode up on a small (150mm) dirt rill as the right-hand wheels moved into a lower area and the crane tipped on its side. No persons were injured.

Incident 2

On 21 June 2021, whilst lifting a 40 ft container, a fully articulated pick & carry crane reversed over a 150 mm concrete slab, resulting in the crane rolling onto its side (figure 1). It was reported that the crane operator deviated from the planned travel route and the dogman was watching the load, and not where the crane was travelling. No persons were injured in this incident.

Incident 3

On 11 April 2021, whilst moving a large generator, a pick & carry crane tipped on its side (figure 2). The crane was operating at full safe working load, travelling on uneven ground and articulated. It was reported that the load monitoring system override function was activated multiple times prior to the rollover. No persons were injured in this incident.

Incident 4

Whilst relocating a mobile pick & carry crane on site, the operator lost control and rolled the vehicle on its side (figure 3). The coal mine worker (CMW) was able to exit the vehicle, however suffered injuries requiring hospitalisation.

Other incidents reported

How did it happen?

The review of the incident investigations identified multiple common causes:

When the above factors were considered, the carrying capacity of the crane may be significantly reduced, resulting in rollovers whilst travelling.

Recommendations

It is recommended that the Site Senior Executive:
