For the fastest and most reliable handling of your bulk goods
The Nemag Clamshell Grab is the lightest and most productive clamshell grab on the market. The productivity increase that you can experience with the Clamshell is the result of our 95 years of experience and input we’ve gathered from customers from all over the world. The Clamshell is manufactured using state of the art technology such as Solid Works and FEM & TACTON Product Configurators.
Best quality for competitive pricing
By using the latest innovations in engineering we have updated our manufacturing process and enhanced our clamshell grab with modular parts. The result is a competitive price, while still using the highest quality high tensile wear resistant steel. The optimized manufacturing process also guarantees a shorter lead time for the Clamshell Grab. This dry bulk grab is available with a 100 ton capacity.
To keep the capital expenditures of the Clamshell Grabs as low as possible we’ve decreased logistics costs by designing this four-rope grab with container shipping in mind. This significantly reduces the costs of transportation to your location.
Lowest bucket maintenance costs
Market research shows that the highest cost of any grab will always be the operating expenditure, OPEX. We want to keep the OPEX of our customers as low as possible. That is why we only use the most durable materials and decreased the number of parts that are open to wear and tear. We’ve also made it easier to reach and maintain the different parts of the Clamshell Grab. That is how we can promise your team a safe work environment and the lowest maintenance costs per tonne transferred.
