For about one year, two duty cycle crawler cranes, type HS 8070, worked twenty-four hours, seven days a week. Each machine was equipped with a 23 m long boom as well as a dragline bucket with a filling capacity of 3 m³.

Every day about 16,000 t of sand and gravel were extracted from depths of down to 12 m. That means a turnover of approximately 330 t per hour and machine. The average diesel consumption was only 24-26 litres per hour.

The complete design of the machine is very well thought out. We achieve excellent turnovers with an impressively low fuel consumption. That’s why the HS 8130 is the perfect machine for extracting gravel.

The HS 8130 has a 23-metre boom and is fitted with a Hendrix dragline bucket 7 ½ HS with a capacity of 5.7  m³. At a digging depth of 8-10 m the duty cycle crawler crane manages 450 m³ of material per hour.
