In July 2017, Duro Felguera Mining & Handling (DF) was awarded an EPC contract that included the design, engineering, procurement, fabrication, construction, start up, testing and delivery of a complete system to unload and store coal at the Port of Lázaro Cárdenas, and transport this coal to the Petacalco Power Station in Guerrero, Mexico. Its scope included the supply of two mobile hoppers, two stackers, one portal reclaimer, three dozer traps, 13 conveyors and the electrical, control and instrumentation design of the complete system. Two of the conveyors were the overland type, transporting 545 t/h (600 stph) of coal from the port to the power station. The total amount of this turnkey contract was around $130 million.

DF subcontracted the basic engineering, design review and control system for the two overland conveyors to Conveyor Dynamics Inc. (CDI). In October 2019, CDI successfully commissioned these two overland coal conveyors. The first conveyor is 2.2 km (1.3 miles) long and includes a horizontal curve with a 400-m (1,312-ft) radius. The second belt conveyor is 3.3 km (2.1 miles) long and includes five horizontal curves with 900-m (2,952-ft) radii and one horizontal curve with 1,200-m (3,937-ft) radii. DF completed the detail engineering, procurement and construction of these two conveyors (Fig. 1).
