A new SENNEBOGEN 655 duty cycle crawler crane has last summer started digging tons of sand and gravel in the Ile-de-France region of France. In July 2015, the French sales and service partner Sygmat delivered the 55 t material handler to the customer A2C materiaux (Fig.). A family-owned enterprise, A2C has been working in the field of sand and gravel extraction and further processing for over 50 years. Around 1.2milliont are extracted from gravel pits in the region of Ile-de-France and supplied to concrete and prefabricated part plants. The material for this is classically extracted using the 551 duty cycle crawler crane using a dragline bucket.With the attached 2.5 cyd dragline bucket, the driver only needs 40 seconds to retrieve the gravel from a depth of up to 10 m.
