Where the equipment forms part of a hire fleet, the equipment should be inspected as detailed below by the hire company on return from each hire contract. As with all construction industry equipment – and in particular items relating to working at height, it is vital that only fault-free, undamaged items are deployed in accordance with the assembly guide to preserve the integrity of the structure, the safety of the users and those around them.

The ALTO HD Tower System components have been subjected to rigorous testing to determine and prove their reliability, safety & capacity. The construction & facilities management industries where this equipment is typically deployed can be demanding environments, and there are occasions in which damage occurs – either through accident or misuse. Serious misuse through significant overloading or use for inappropriate tasks can impair the integrity of components.

Equipment must be inspected post-use properly so that remedial action can be taken. Equipment that has been misused may be unsafe and should not be used. No liability will be accepted in relation to equipment that shows signs of misuse. Any product or component which fails any of the inspections set out in this document must be withdrawn from use and quarantined for further inspection, repair or replacement as appropriate.

ALTO HD Tower System equipment should not be modified in any way and should only be repaired by the manufacturer - Lakeside Industries Ltd - or by authorised agents. If it is suspected that equipment has been modified or repaired by any other provider, the equipment should be quarantined and returned to Lakeside Industries Ltd for free inspection.
