How the test weight stacking system works
The system comprises of interlocking 5Te and 1Te cast iron weights. The recessed 5Te weights accept up to 4 off, 1Te weights, giving an assembly weight of 9Te. To maintain balance, the 1Te weights can be located in 3 positions inside the 5Te weights – either centrally or at the end.
The 1Te weights slot inside the 5Te weight and require no additional securing. Each 1Te weight is positively secured to the 1Te weight beneath it by a positive interlocking design. By way of integrated tabs in all corners, the 5Te weights are designed to lock securely onto either a cradle or a lower weight, even when full of 1Te weights.
Finer adjustment to the load can be achieved by utilising the fully compatible 500kg, 250kg or 125kg weights.
Each weight has integral lift points.
