At Nemag, we believe in the power of innovation to help you increase your bulk handling efficiency and decrease your operational costs. In close cooperation with leading bulk terminal operators, crane manufacturers, technical universities and other stakeholders in the industry, Nemag continues to develop new products for the dry bulk industry. Improving unloading efficiency and striving for the lowest handling costs per ton material transferred are key objectives.
Making the right choice
There are several grab types available, each with specific characteristics and benefits. When choosing a grab, it is important to be aware of the fact that a grab is of fundamental importance on overall performance.
The key challenge is to find the best grab solution and unloading procedure that leads to the highest average unloading performance. In addition, the impact of the grab type on auxiliary equipment costs such as trimming equipment and staff must be considered, as well as maintenance costs.
When it comes to the type of materials it will handle, the choice of grab is more than looking at the bulk material, payload and deadweight. The combination of appearance, density and moisture content of bulk material make it extremely important for terminal operators to choose the right grab. This will avoid overloading the installation, prevent leakages and optimise the overall terminal performance. Choosing the ideal grab also requires a good understanding of prevailing conditions:
» Will unloading be with shore-based cranes or floating transshipment?
» What is the size of the ship, barge or a bigger vessel?
» What type of crane is being used?
The clamshell grab
Nemag’s goal is clear: to create the most productive grabs on the market. One recent addition is our NemaX®, the most productive iron ore grab in the world. Now we are introducing our next innovation — the Clamshell Grab, the lightest and most productive clamshell grab on the market.
This achievement is the result of combining input from customers from all over the world and our 95 years of experience, supported by state-of-the-art design tools such as Solid Works, FEM analysis and TACTON product configurators.
Grab with low maintenance costs
Market research shows that the highest cost of any grab will always be the operating expenditure, OPEX. We want to keep this as low as possible for our customers, which is why we use the most durable materials and have also reduced the number of parts that are susceptible to wear and tear. In addition, we have made it easier to reach and maintain the different parts of the Clamshell GrabM.
This is how we can promise your team a safer work environment and the lowest maintenance costs per ton transferred.
Competitive pricing
By using the latest innovations in engineering, we have further streamlined our manufacturing process and enhanced our latest clamshell grab with modular parts, which all adds up to an extremely competitive price.
Short lead times & reduced logistics costs
Our high-performance Clamshell Grab has been standardised for production, enabling a shorter lead time from your order to the moment you can start experiencing the increase in productivity that the Clamshell GrabM brings.
After buying a grab, the last thing you want is high transportation costs to bring the grab to your terminal. That is why our reinvented clamshell grab has been designed with container shipping in mind. This drastically reduces the costs of transportation.
The design of the Clamshell Grab also makes it very easy to assemble and disassemble when needed.
Fully customizable grab
The Clamshell Grab is available as a highly customisable modular grab for lifting capacities starting at 20 tonnes up to an 85-tonne safe working load. However, if you are looking for a non-standard clamshell grab, please do not hesitate to contact our sales team. They will be happy to help you with all the special requests that you have.
