Port Product Review: CRANES
By Diane Mettler
Today’s ports couldn’t function without the large variety of cranes available to hoist and move cargo. Luckily, there is a crane out there for every kind of project. Below are a few of the options available.
Company: Demag
Product: Process cranes
Function: To handle specific applications such as: aviation, storage containers, and recycling and bulk material.
Special Features: With a wide range of accessories and auxiliary equipment, Demag can adapt its process cranes to the individual requirements of your application.
How it works: Depending on the branch of industry, specific working conditions must be taken into account for. The typical Process Crane project planning includes the following critical steps: conceptual design; functional specification; technical specification; design, manufacturing and testing; and lastly delivery, final testing and start-up.

Company: Fantuzzi Noell
Product: MHC 250 (Mobile harbor crane) — company also offers RTGS and STSs as well as others
Function: Designed to handle a variety of cargo, and offers options for more flexibility.
Special Features: Reaches a 52-meter radius with 35.1 tons down spreader at 66% of tipping load. Service life is approximately U5 (500,000 cycles). You could increase the load to 75%, but that will reduce the service lifetime.
Two hydraulic units distribute the forces for slewing movement. Sizes of leg pads, as well as number of traveling axels, can be adjusted according to the capacity of the quay. The double winch (4 ropes) is also optional.
How it works: 16 containers is the crane’s effective outreach — that’s based on a normal quay with 4.7 meter separation between crane (outer side of leg plates) and the land side of the ship.

Company: Gottwald
Product: Mobile Harbor Cranes
Function: Designed to handle all forms of cargo — containers, bulk, general and project cargoes, and for use at both universal and special-purpose terminals. Special Features: The cranes have radii of up to 56 meters and lifting capacities of up to 200 metric tons. Crab steering creates a tight turning circle to enable accurate positioning on the quayside. The diesel-electric drive offers not only a high degree of reliability coupled with low operating and maintenance costs, it also makes the crane independent of external energy sources. As an option, operators can switch over to an external electricity supply.
How it works: The cranes are designed to cope with the tough conditions encountered in ports. The innovative, robust axle concept, which enables all the axles to be individually steered and includes large tires and vertical compensation of up to +/- 250 mm, provides the following benefits: easy maneuverability; easy handling of rails and uneven terrain; a tight turning radius; and reliable travel to the next quay and in storm-force winds.
Clients: Clients spanning 90 different countries

Company: Kalmar
Product: Electrical Shuttle Carrier®
Function: The carrier sets down and picks up containers on the ground, eliminating waiting times. Ship-to-shore cranes lift
containers from the vessel and place them on the ground, under the crane’s back reach, from where they are then collected by shuttle
carriers and transported to the automatic stacking crane buffer area. This combination achieves high productivity with the lowest number of horizontal transportation vehicles.
Special Features: Users experience reduced fuel consumption and lowered CO2 emissions. Additional options for lowering emissions include an energy storage system and a stop-and-go feature, which shuts down the engine when not moving.
How it works: The Electrical Shuttle Carrier combines the latest in green technology with high productivity. The new power package with variable speed generator technology features a stage 3a engine with SCR (specific catalytic reduction) technology and an electrically controlled viscous fan. The power package is thus ready for hybrid use. The shuttle carrier has an electrical drive, an electrical winch hoist, and in the hybrid version also an electrical brake control for optimized energy recovery when braking.
Customers: Wide variety of clients worldwide.

Company: Konecranes
Product: cRTG, the new electricity-fed RTG and Fuel Saver RTG
Function: The cRTG, in addition to using energy from the electric network, can also act as a small power plant, taking the electricity generated during braking action and feeding it back to the grid. For the terminal, less energy from the power station is needed.
The Fuel Saver RTG yields fuel savings of up to 25-30%. The system optimizes the efficiency and the fuel consumption of the diesel generator by adjusting the engine’s RPMs according to the actual power requirement. The diesel engine is driven with optimal efficiency at all operating points, eliminating high-speed idling completely and guaranteeing constant, full-scale productivity.
How it works: The electricity-fed cRTG is equipped with a cable reel, a feeding cable and a transformer station, which feeds low-cost electricity from the grid to the crane. Using energy through the cable, the crane can be operated on one stack, and the feed point can be either at one end of the operating area or at the center.
As for the Fuel Saver RTG, the programmable logic controller calculates how much power is needed, and the diesel engine speed is adjusted to be equivalent to the needed power. The diesel engine is driven with optimal efficiency at all operating points, which
eliminates high-speed idling completely.

Company: LHM
Product: A wide range of Mobile Harbor Cranes
Function: Ideal for handling everything from containers to bulk goods, general cargo and even heavy lifts up to 208 tons.
Special features: The undercarriage is a patented Liebherr mobile harbor crane chassis, where the number of individually mounted sets of four wheels each can be easily adapted to comply with the most stringent quay load restrictions. Alternatively, a portal or a barge can replace the basic undercarriage concept.
Different configurations of winches and drive systems (power packs) are available to conform to variants of professional
cargo handling.
Liebherr’s patented Cycoptronoic® (cycle optimizing electronic crane control system) allows for direct load positioning.
How it works: The operator will experience versatility and flexibility, especially in general cargo handling, with continuously changing operating appliances and handling methods, including: changing from one lift device to another in minutes; special controls and individual pre-selectable lifting methods; and automatic recognition and pre-selection of the lifting device through Liebherr Litronic® control system.
