US rubber tyred gantry crane manufacturer Shuttlelift has launched two new double-beam models: the DB90 and DB165. The manufacturer said it developed the gantry cranes in response to requests from customers in the concrete and steel industries for gantry cranes that more closely match their load requirements.
According to Shuttlelift, the DB90 provides a solution to customers with loads that fall between 140,000 pounds (63,503 kg) and 220,000 pounds (99,790 kg) in weight, while the DB165 is suitable for loads that weigh more than 300,000 pounds (136,078 kg). According to Shuttlelift, the two new models will enable customers to safely and efficiently carry loads at a price that is in line with the capacity they need.
Speaking about the DB165, Brock Rubens, Shuttlelift industrial sales and marketing manager, commented, “The feature that really stands out is how the full crane capacity can be traversed side to side, the full width of the crane. It is not a crane that is only rated for full capacity in the centre.”
The DB range has what Shuttlelift calls an ‘intelligent operating system’, which allows for multiple outputs including general engine performance, real time measurements of general machine operations, performance trouble shooting, and complete systematic control. A Bluetooth adapter allows for convenient remote diagnostic communication with the operating system via smartphone, tablet, and computer.
The DB cranes’ columns are tapered both in the longitudinal and transverse directions, providing extra stablity, while their formed box-section designs maximises their durability by minimising points of load stress concentration, said Shuttlelift. In addition, a cantilever wheel frame design provides increased efficiency if tyres need to be serviced or replaced.
The crane has fully proportional controls to allow precise movement of all crane functions and, as the hoists are mounted to the lower side beam, the operator can easily see the reeving of the wire rope and can perform maintenance without an access platform, Shuttlelift said.
