The Beaver 3S industrial chain block has improved reinforced side covers, made from heavy duty steel to ensure full protection of the vital gears, shafts, and bearings. The load chain is made of high resistance Grade 80 alloy steel that has a black finish, is heat treated, and is calibrated and marked according to ISO 3077 and ISO 1834. Beaver ‘ID’ plates and rivets are supplied in stainless steel (a non-conductive material) in order to avoid dangerous sparking, making them ideal for underground mining.
