Our Mission: To protect, preserve and promote the natural integrity of Radnor Lake through land acquisition, environmental education and park support.
Chains up to 12 mm thick are generally portable: you can carry them around on your bike every day. The long ones will be really heavy though, so please check the weight. Above 12 mm the chains are more suitable as stationary locks: you would leave them wherever you lock your bike for long periods of time.
If, however, you are lifting a more bulky, or deeper item, the load centre will increase. The diagram on the right shows this. Trucks A, B & C have progressively narrowing load centres. This means that less effort will be required to life the same 2,000kg weight.
