Container Technics NV


1) Connection of spreader to crane:




Connect lifting wires (2 x 2 legs) to the cranehook.
The legs should not be twisted.

Connect wire (with main spring) of shifting gear to
cranehook (only for semi‐automatic use).

► The spreader can be lifted.

2) Pick up container:



Position spreader on top of container. Using the guidance plates.

When all guidance plates (3) are in contact with the container, the spreader is correctly positioned.

Lowering the spreader on top of the container will lock the twistlocks.
Sign shows “locked” to the crane driver.


► The container can be lifted.

— All 4 twistlocks should be locked, container weight should never exceed SWL of spreader.
— Guidance plates can only be used for standard ISO‐containers (no extra long or extra wide containers).

3) Discharge container:


When container is placed on its position, the cranehook is to be lowered to slacken the wire of the shifting gear.

When sufficiently lowered, the sheave will be at the lowest possible position (position 2).

Lifting the wires again will unlock the twistlocks.

Sign shows “unlocked” to the cranedriver.

► Spreader can be lifted.


1) Manual operation:



Insert handle in spreader end.

To lock, turn handle.

Sign shows lock on top, container can be lifted.

To unlock: turn handle to the other side.

Sign shows unlocked on top, spreader can be lifted without the container.

2) Maintenance & repair:

Condition of load bearing components (wires, lifting eyes, frame, twistlocks) should be checked before every use.
► Permanent deformation is not allowed.
► Wire ropes to be inspected in accordance with EN‐13414.
Moving parts (twistlocks, locking pins, operating rods) are to be kept free from debris and greased regularly.
Repair should be done by competent person.
Spares are available on request.

3) Problem solving:

— Twistlocks don’t fit all 4 in ISO‐holes.

► Frame is deformed.
► Container is deformed.
► ISO‐holes are damaged/filled with debris.

— Twistlocks cannot be locked.

► Main spring is extended.
► Movement of locking pins is prevented.
► Movement of operation rods is prevented.
