We have been sent a series of photographs of a team of arborists in the UK removing a series of pine trees. They look very professional and have a wide range of kit to do the job, including an aluminium boomed trailer crane.
The crane - a Böcker - is being used to remove the tree trunks, lifting modest-sized sections in a safe and efficient manner. The road is properly cordoned off and outrigger mats used.
However, some of the photographs show the crane being used to lift a tree worker into the tree to attach the slings with a sling-type Bosun’s chair. While many powered access professionals frown on this form of access, with good reason, they have their place. BUT... that very much depends on the device itself - this one looks like an abseilers' sling - and the lifting machine used.
Assuming that the ‘chair’ itself is kosher, the next focus is on the crane. In many jurisdictions machines used for lifting persons need to have a full formal Thorough Inspection every six months, while cranes or other machines used to lift loads only require an annual inspection. Most trailer cranes are designed to take a full EN280 work platform attachment and so have the additional required safety features required for a dedicated work platform.
Finally, one photograph seems to show the man, having been lifted into the tree, attaching the sling. The question is does he then climb down, or did he ride with the load - the tree section?
So, is this one for our Death Wish series?
Certainly, at first glance it looks like it is, but to be definitive more information would be required.
