Description
- The present invention has for an object a loading basket for aerial platforms, telescopic handlers or similar operating machines.
- Loading baskets are known which comprise a rectangular flat bottom capable of supporting operators and equipment, around which there are arranged walls which have the function to prevent any accidental fall to the ground of the operators or of the equipment.
- The baskets are arranged for being connected to a telescopic lifting arm by way of suitable coupling devices.
- The known baskets work with great efficiency when used for work activities at height which require the manual intervention of operators, possibly implying use of portable tools which tools, as said, can be easily transported in the basket itself.
- However, there are some types of activities which are not implementable through the use of known loading baskets, and which therefore may result complicated, ineffective and sometimes dangerous.
- Consider for example the case of asbestos remediation, wherein the asbestos sheets forming the roofing are removed.
- In this case one or more operators are required to walk on the roofs while performing their work and in so doing, they are duly secured to a fall arrest harness anchored to the roof.
- The roofing sheets are removed by the operators and restingly placed onto a loading platform (for example a pallet), which is then lifted by a crane or the forks of a telescopic handler; such platform is lowered to the ground from time to time for transferring the removed asbestos sheets towards the flatbed of a truck or the like.
- This solution can be extremely dangerous in that, if the asbestos sheets burden is not perfectly secured to the pallet, it could slip off while being handled and fall to the ground, thus resulting in asbestos dust being raised in the atmosphere.
