PEINER ship grabs – cost-efficient in procurement and operation

For 70 years PEINER grabs have been present on the market and are today distributed by PEINER SMAG Lifting Technologies GmbH, a global player among the suppliers of bulk handling equipment. Common is their dual scoop grabs suitable for the maritime sector. In addition to the universally applicable rope grabs for general cargo cranes, the company offers electro-hydraulic motor grabs, which are used for single rope cranes and require a power supply from the crane. The most widely used motor grab is the MZG/L series. High handling quantities per loading cycle is the outstanding feature of this type of grab. By means of power-controlled hydraulic pumps, the electrical power supply is very efficiently converted into handling power. The motor grab achieves an optimum filling degree through high closing forces. No matter if light, medium or heavy bulk materials – with its customized dual scoop design the grab copes with different materials to be handled. One key advantage is that the grab control can be integrated into the control of the crane and operated from the crane cabin.

Among the rope grabs, the radio-controlled single-rope grab (EGF), is the predestined ship grab. Many bulk carrier operators use this proven and continuously developed rope grab in the tough cargo handling business, for good reason: Using this model allows any shipboard or container crane to handle bulk material in the shortest possible time without additional equipment. Their major advantage: they can work without power supply from the crane – the operator just has to charge the batteries and the grab is ready for operation. The PEINER radio-controlled single-rope grab can be precisely controlled wirelessly with the portable, robust handheld terminal. It enables reliable, interference-free radio communication up to 500 m. High-performance accumulators of the remote control guarantee continuous operation for up to 24 hours and can be easily changed within a few minutes without any extra tools.

PEINER SMAG Lifting Technologies, Salzgitter, Germany, introduces high volume radio controlled single-rope grab (EGF 60) for the operation with a container crane at Port of Aarhus, the largest container port in Denmark.

At the beginning of 2015 PEINER SMAG Lifting Technologies GmbH (PSLT) was approached by its customer Port of Aarhus with a request for a specific grab that can be operated with an existing container crane for the handling of bulk cargo. As most of the proven grabs could not be used to fulfill this requirement the company felt encouraged to develop an efficient solution tailored for customer’s needs. This was a challenging technical task: Since the crane is not equipped with the necessary hoisting gear/winches, mechanical two-rope and four-rope grabs are ineligible for operation with this type of crane. Hydraulic and electro-hydraulic motor grabs require a wide range of accessories to be installed on the crane and would go beyond the planned budget, hence also these grabs could not be taken into account. Another alternative is the use of Diesel grabs, however they are known to have a negative impact on the industrial safety and besides they provide limited operational flexibility. For the required handling capacity of more than 30 m³ the grab must have a powerful engine as well as an exhaust system to meet the permissible emission levels.

Finally, after all possibilities had been checked, PSLT decided for the only workable solution: The PEINER radio controlled single-rope grab (EGF) has already proved to be successful on board of bulk carriers over the past 15 years, however the grabs were primarily used for handling volumes from 12 to 15 m³. The goal of the Aarhus project was to construct an EGF with a volume of 32 m³ in order to use the existing crane lifting capacity even during grab operation. These specific grabs for the handling of animal feed, wood pellets and wood chips at the port of Aarhus are the largest radio controlled single-rope grabs ever built by PSLT.
In addition to a new design engineering of the basic unit with special cylinders the grabs offer a sensor attachment transmitting actual operational states to the crane crane controls and crane driver by wireless communication. This innovative feature helps crane operators to work even faster and more effective. The grabs are provided with a centralized shift of lubricating points and therefore easy to maintain.

An intelligent climbing assistance system ensures the highest standards of job safety for the maintenance staff on the job site. The grabs are assembled with a universal suspension that enables the operation both lengthways and crosswise. Our scope of supply also includes an adapter unit in the form of special load traverses to connect the grab with the crane headblock. The traverses feature a range of supplementary technics, e.g. proximity sensor, light and camera systems, control cabinets and electrical plugs.

Additionally, the EGF 60 is equipped with a unique locking system that considerably reduces the grab height. This feature particularly supports ship to ship bulk handling processes, for example during transportation of wheel loaders into the ship’s hold, where high structures on deck are often blocking the way. The grab shell can easily be fixed in position by hand without using any tools so that the grab height is reduced by half.

It is the first time that a PEINER radio controlled single-rope grab of such a large size will be operated at a container crane. We expect this pilot project to serve as a positive drive for further developments in this field and sincerely hope that it could be a starting point for the realization of more projects with this innovative technology. Jens Hvidegaard Dissing, Project Manager at Port of Aarhus, who accompanied the project from the idea stage to the first commissioning, is convinced about the new development. “Bulk Material Handling is essential to the success of ports. Our goal was to have an intelligent solution for our container cranes, with significant better efficiency in terms of speed and handling volume. We had an idea, and we found the right product: a PEINER radio controlled single-rope grab, that combines all the required features, together with additional benefits to meet today’s material handling challenges in the port of Aarhus.

Biomass has quickly become a global business due to a worldwide interest in modern energy. PEINER SMAG Lifting Technologies GmbH (PEINER SMAG) is already well prepared for this greater demand in renewable energy sources. The leading manufacturer of lifting equipment offers individual solutions for the handling of biomass by providing the right grab for almost all lifting devices. All of the PEINER SMAG grabs have been designed with sustainable and ecological construction. The company has recently implemented an integrated management system (IMS) which combines the individual areas of quality, environment, protection of employment and energy into one grab unit. This new system was successfully certified by TÜV Süd in accordance with ISO 9001, 14001, 50001 and OHAS 18001.

The technical and economical growth potential of reneable energy for the production of power, heat and fuels is substantial, with biomass covering over 10% of the world’s energy demand. The transshipment of biomass volume in ports and terminals, waste-to-energy plants, timber mills and co-generation plants is ever increasing. Apart from agricultural goods such as corn, sugar cane, canola and other food crops, biomass products such as timber, bark, saw mill waste, wood chips and pellets are handled. In addition, organic waste from household rubbish and residual products from the food industry also play an important role in the handling of biomass.

With its wide range of applications, PEINER grabs can handle all kinds of biomass materials, with certain grabs tailored towards the special needs and requirements of particular industries. In the timber handling industries the use of hydraulic and electro-hydraulic timber grabs are primarily common place, with operators benefit from their high-load capacity, high closing force and special shaped tongs for the handling of timber logs. These key features enable the grab to handle logs in any variety, whether round timber, bundled and even single logs safely and efficiently.

When handling bulk materials such as wood chips and wood pellets, crop or organic waste, motor grabs or four-rope grabs are generally used. Due to their technical features PEINER motor grabs offer numerous advantages, especially for their use in incinerator plants. The PEINER MMG/MMGL series of motor “orange peel” grabs are already successfully established within the incineration market. Its specially designed construction allows for fast operation and is highly energy efficient. The optimal installation height, low centre of gravity and robust design ensures the flexible use of the MMG/MMGL series. Thanks to individually driven shell segments, the motor “orange peel” grab adapts to suit the materials being handled. The shell segment design and the number of shell segments on the grab can easily be adapted to meet customer requirements. Hydraulic pipes, wiring and connections as well as the cylinder barrel and piston rod are fully protected from external elements.

Depending on the field of application, PEINER SMAG offer customers the option of mechanically operated rope crabs which are available in clamshell or orange peel grab design. Both types are considered solid and reliable.  The balance ratio between the dead weight and grab volume or crane capacity respectively; provides a good level of penetration into the bulk material supporting higher throughput rates.

Conclusion:

PEINER SMAG discerns a positive trend in the handling of biomass and continues to expand its efforts in providing high quality reliable grabs in this market, particularly in the waste incineration industry. An existing framework agreement with a major client for the delivery of motor grabs to operate in the incineration plant has been highly successful with incoming waste and the bi-product of ashes handled by the MMGL/MMTGL series PEINER motor “orange peel” grabs. From PEINER’s excellent track record and successful implementation of biomass grabs, further orders from this market segment are expected.
