Sigma is expert at supplying plant and equipment spare parts to civil engineering companies all around the world. We offer a wide range of spares for earthmoving equipment, trucks, cranes and forklifts by the likes of Caterpillar, Komatsu, Hitachi, Volvo, Terex, Grove, P&H, Tadano, JCB, Deere, Atlas Copco, Leyland Daf, Bedford, Landrover, Cummins, Detroit Diesel, Doosan, Hyster, Linde, Yale and Lancer Boss. Sigma offers a procurement service for just about every type of used plant, in fact weve been doing this for many years working with existing clients. We dont own any plant ourselves, what we do is locate what you are looking for and offer you a selection of suitable equipment. We are working for you and are not trying to sell you some equipment that is either unsuitable or in a bad state of repair. This is what makes Sigma quite unique, we are your agent and not merely a used plant dealer.
