ELME Spreader Model 877 WTP version is a container and trailer handling spreader for the handling of all laden ISO, WTP and US-domestic containers weighing up to 40 tonnes. 877 WTP is designed for use with reach stackers.
The strong and basic concept offers distinct advantages, such as two parallel telescopic beams, assuring max overlap. The beam sections are dimensioned to absorb not only the vertical, but also the very considerable horizontal forces.
The twistlock system is manufactured in a rugged design and is well-proven since many years. 877 WTP has hardened, pendulling ISO twistlocks, hydraulically activated with electrical and mechanical interlocking against faulty locking and unlocking.
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. Integrated in each leg/foot is a clamping sensor that signals to the driver that the trailer is ready to be lifted.
The folding is sequential as standard but outside of the 30ft-position it is parallell for reduced folding/unfolding time.
TELESCOPING, SIDESHIFT AND ROTATION SYSTEM
Extension is powered by one hydraulic cylinder inside each beam. Sideshift is executed by two hydraulic cylinders on the outside of the mainframe.
The WTP option built into the spreader endbeams allows the operator to hydraulically change the twistlock positions to handle ISO and US-domestic containers as well as WTP containers.
