We understand that coke-producing facilities run around the clock. With short maintenance intervals and less time for major overhauls, failures on a coker cranes impact production times and can cause potentially unsafe situations for technicians. That’s why all of our coker cranes are built to withstand your toughest conditions.
Our cranes employ an extremely high drum-to-sheave ratio—30:1 vs. the standard 24:1. A larger drum size reduces stress placed on the wire rope by reducing the sharpness of the curvature around the drum. This innovative rope reeving system is estimated to extend the lifetime of the ropes by up to 40%*, significantly reducing maintenance costs over time.
We equip all our coker cranes with a built-in overwrap preventer. In the unlikely event of a load drop, this safety feature prevents the wire rope from wrapping around the drum in the opposite direction.
Portions of wire ropes in continuous use can become damaged. We add three times the needed rope space on our coker cranes, so you can remove damaged portions and re-reeve the rope up to three times, saving you time and money.
Our bearings are built to keep you running for a total of 50,000 hours, much longer than standard crane bearings. All gearings are 58 HRC, carburised, finish-ground and built to AGMA Class 11 minimum. We carburise our gears for the strength needed to withstand daily, near-constant use. For easier maintenance and lubrication of fittings, we grouped them together at one central point.
To help prevent overloaded or unbalanced loads, we use intelligent load cells on each drum with a load-summing feature. Lasers detect the exact weight of the load—even through complicating factors such as multiple ropes or hooks.
Electric Overhead Traveling (EOT) coker cranes are commonly found with spans up to 46 metres, and they feature independent travelling cabs for improved operator visibility. This design is often found in wide span layouts that have a separate drying pad alongside the pit. Coke that is discharged into the pit is moved to the drying pad for about 24 hours until it is sufficiently dewatered to be handled by a conveyor.
The single leg gantry (SLG) crane configuration fits layouts that benefit from the hopper-side runway rail being installed at the grade level. This arrangement saves the cost of an elevated runway structure on that side. SLGs can be used with travelling hoppers, an arrangement that increases the crane throughput by eliminating long travel in the crane work cycle.
The semi gantry coker crane with cantilever has the same benefits as the SLG without cantilever. It also provides opportunity for narrower pit widths and additional storage outside the gantry leg. The cantilever allows the hopper to be located outside the basic pit dimensions, making a better fit at some sites.
