ELME Piggyback slave attachment 953 is a removable unit under any 20ft ISO container spreader − dedicated for the handling of trailers, swap bodies and bottom lift containers. The typical property of a slave attachment is to be easily attachable and detachable. It is also it’s main advantage and 953 is the given choice where container handling equipment is already in use and the need for bottom lifts arises. 953 is the economic choice at a terminal with relatively few bottom lifts and a desire to create flexibility in a fleet of container handling machines by switching from machine to machine. 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. HYDRAULIC FUNCTIONS 953 has two hydraulic functions; clamp/unclamp and fold/unfold of legs. Only one hydraulic supply group is needed, as all functions are controlled through solenoid valves on the attachment. INSTALLATION, CONTROL AND PROTECTION SYSTEM Quick-change couplings and plug/socket connectors are used to hook up the attachment to the truck or to the spreader. When used under spreaders it is recommended to use a system, developed by ELME, eliminating the need for any adaptations to the truck. Hydraulically and electrically, the spreader is disconnected from the truck and plugged into the slave attachment instead. The hoses and cables from the slave attachment are plugged into the connectors on the truck or on the spreader. The spreader functions locking/unlocking are then used for leg folding and clamping respectively. Truck indicator lights advise the operator when the piggyback slave attachment is correctly seated, clamped or not clamped. The system ensures that the twistlocks connecting the spreader to the slave attachment cannot be opened inadvertently DISCLAIMER All specifications are subject to change without notice.
