Spreader Model 8510 is a telescopic piggy back spreader for intermodal handling of laden ISO containers and trailers up to 41 tonnes. 8510 is designed for mounting on Rail Mounted (RMG) or Rubber Tyred Gantry (RTG) cranes. The strong and basic concept offers advantages, such as two parallel telescopic beams, assuring max overlap. Beam sections are dimensioned to absorb not only the vertical, but also the very considerable horizontal forces. TWISTLOCK SYSTEM The twistlock system is manufactured in a rugged design and is well-proven since many years. 8510 has hardened, pendulling ISO quick exchange twistlocks, hydraulically activated with electrical and mechanical interlocking against faulty locking and unlocking. EXTENSION AND HYDRAULIC SYSTEM Extension is powered by one hydraulic cylinder inside each beam. Double electric motor- and pump assemblies assure simultaneous telescoping of both beams. Spreader can be operated with one electric motor and pump. GRAPPLE LEGS SYSTEM The leg arrangement is done according to the ELME patented system which is a load clamping system that involves all four foldable grapple legs in an automatic sequence. Thanks to this feature the spreader can be lowered between containers that are block stacked front to front and side to side. The feet are designed according to European standard and made of Strenx® 900E material (meets S 890 QL) to extend life time. Sensors (integrated in the feet) detect when the trailer is clamped and send signals to the indication system. To avoid unclamping, a signal is also sent as soon as the container/trailer is lifted off the ground. CONTROL AND PROTECTION SYSTEM Control voltage on the spreader is always converted to 24V DC for safety and reliability. Electrical systems monitor the state of the spreader at all times. Indicator lights advise the operator when the spreader is correctly seated, locked or not locked. Each signal is a precondition for the important protection functions of the spreader, such as twistlock activation, telescoping and lift interrupt. DISCLAIMER All specifications are subject to change without notice. A list of options enables you to adapt the spreader more precisely to your needs and further information is available on request.
