Approval Drawing

For special designed guards or for instances when customer approval is required Solon Systems Ltd or its subcontractors will provide “standard format” approval drawings in Auto Cad format.  These will show the general concept of the guarding relative to the machine position.  Should the customer require additional detail this must be specified prior to ordering and we reserve the right to adjust our prices accordingly.

Approval drawings must be approved in writing by an authorised employee of the company by signing each drawing and providing the printed name and date of signing.  Drawings must then be returned within one week of issue to ensure that manufacturing commitments from Solon Systems Ltd and its subcontractors can be maintained.  Failure to return approved drawings within this time frame may affect the delivery dates.

Changes made by the customer after the date of approval of guard drawings may incur additional costs.  We reserve the right to pass on these additional costs to the customer.

Changes must be forwarded to Solon Systems Ltd in writing by the authorised employee of the company and a revised purchase order must be issued before the changes/variations are implemented.

Final manufacturing drawings will not be issued or commencement of manufacture until the signed approval drawings are received by Solon Systems Ltd and its subcontractors.

Should the customer require some other means of fixing the machine guarding in place then Solon Systems Ltd and/or its subcontractors will investigate the feasibility and provide the customer with the additional costs accordingly.
