Telescopic container spreader
(for loaded container reach-stacker) ELME
817: 20'-50'

ELME spreader Model 817 is a telescopic top spreader for the handling of loaded ISO containers weighing up to 45 tons. It is designed for use with reach stackers. The basic concept of this type of spreader offers distinct advantages such as:
- two parallel telescopic beams, assuring max overlap
- beam sections dimensioned to absorb not only the vertical, but also the very considerable horizontal forces
- floating twistlocks, allowing movements up to 10 mm in each direction, made of 42CrMo4 forged steel, extremely easy to service.

Two hydraulic cylinders slide the spreaders mid frame smoothly over synthetic wear pads up to 800 mm to either side. A slewing ring of the highest quality is driven by a hydraulic motor via a satellite type gear reduction system. Rotation is 95° to one side and 185° to the other side.

Each twistlock is protected individually against unwanted rotation by a mechanical system. Additionally, electric signals from all land pins simultaneously, indicating that all twistlocks have landed properly, are preconditions for the turning of the twistlocks. With the container lifted, the twistlocks can not be turned. A signal is available to the truck to block the hoist function if the twistlocks are not fully turned. Another signal is given to stop the downward movement of the boom as soon as the spreader has landed properly on the container.With twistlocks %u201Clanded%u201D and/or "locked" the extension/retraction function is blocked. Three indicator lights monitor the "locked", "unlocked" and "landed" positons of the twistlocks. All lights will start to flash if any of the sensors is out of order, or has continued to send its signal longer than usual.
