Coker crane

The coke pit is the production heart of a petrochemical plant, a harsh environment full of moisture, corrosive fumes and abrasive dust. Work is fast and continuous, and downtime is crippling to production. WeiHua can provide lifting equipment and service that can meet these challenges safely and efficiently.

LOAD CONTROL TECHNOLOGIES REDUCE STRESS ON PEOPLE AND MACHINES

Weihua proprietary load control technologies are software programs that operate in the background of our coker cranes, making the operator’s job safer, easier, and less fatiguing. These programs also reduce stress on controls and machinery.

DynAGrab synchronizes the hoisting machineries, sharing the bucket hold and close hoists properly between them, reducing overloads and increasing rope and mechanical component life.

DynaTrack skew control reduces wheel and rail wear and reduces stress on wheels, bearings, rails, rail attachments and support structures.

DynAPilot sway control reduces load sway, reducing collisions with hoppers and pit walls, reducing damage to buckets, hoppers and the pit.

Our coker cranes include technologies that promote safe and reliable operations, improve productivity and maximize service life. 

GRAB CONTROL - DYNAGRAB

The efficiency of your coker operation depends on your operators’ ability to pack full buckets quickly. Our proprietary grab control feature automates the sinking and filling process and alerts the operator when it’s time to lift the load, resulting in fewer trips, shorter load cycles and less operator training. REGENERATIVE NETWORK BRAKING - DYNAREGInstead of dissipating heat through resistors, regenerative braking returns runoff power to the energy grid of the crane. 

SWAY CONTROL - DYNAPILOT

By minimizing load sway, sway control can help reduce the risk of excessive load spillage or bucket impacts with obstacles such as the hopper or pit wall. Sway control makes new operators more confident, increasing safety and productivity and reducing training time.

AUTO-STEERING CONTROL - DYNATRACK

Inaccurate tracking (also known as skewing) can be a major problem for long span bridge-style coker cranes. Auto-steering control (DynaTrack) employs laser sensors for precise tracking along the runway, which can drastically reduce wear to wheels and rails, stresses to crane structures and wheel bearings and the possibility of structural overloads.

DATA ARCHIVING - CRANE MONITORING SYSTEM (CMS)

Monitor more than 400 data points and store up to four years of data with this optional feature. Data is routed to the operator’s cab and the control house.
