Upgrades / Refurbishments


At AJH we have the facilities to not only upgrade your machine but certify your machine to the latest RIS-1530-PLT issue. Whilst we will upgrade your machine with the lastest techhology in order to comply with these regulations, through a pre upgrade inspection we can capture any future potential issues which are caused through heavy use in service. As a result, the machine you recieve back will be ready to be put to work after extensive testing and inspections. Services we offer include but not limited to:
