Bull Dog hoist products were designed, & developed exclusively for Certex in 2005. The entire range meet or exceed British, EU & USA standards. The chain & lever hoist range is fitted with a "loadsafe" overload device which minimizes the risk of damage & injury to either the product being lifted & to the hoist operator. Bull Dog is used extensively in the on & off-shore Oil & Gas Industries, steel mills, government utilities & mining.
