Rubber lifting belt is multi-layer silica gel fabric folded with cover rubber outside the belt core. It can be classified in heat-resistant lifting belt and common lifting belt as per application temperature while can be classified in full-cotton, Dacron and cotton, nylon and EP lifting belt as per core material.
1.Physical properties and level of cover rubber.
It can be divided as type D for heavy-wear, type L for middle-wear and type T for high-temperature material conveyance as per wear and load of material.
2.Wide specification of lifting belt: 150 200 250 300 350 400 500 600mm etc.
3.Technical requirement of lifting belt.
