Container Booster Container Leveler

A Container Booster is a fast and easy solution to raise the container off the ground, by lifting the container from one bottom corner and leveling it with the ground in minutes.
A hydraulic bottle jack is then placed under the booster to raise the container off the ground.

How are containers locked together?

The lower containers stand on foundations capable of withstanding the stack pressures which arise. … The containers are connected together by single or double stacking cones or twist locks. The entire stack or container block is lashed using lashing wires or rods and turnbuckles.
What is Container Lashing? When a container is loaded over ships, it is secured to the ship’s structure and to the container placed below it by means of lashing rods, turnbuckles, twist-locks, etc. This prevents the containers from moving from their places or fall off into the sea during rough weather or heavy winds.


A twist-lock and corner casting together form a standardized rotating connector for securing shipping containers. The primary uses are for locking a container into place on a container ship, semi-trailer truck or railway container train, and for lifting of the containers by container cranes and side-lifters. Wikipedia
To add a layer of protection to this process, a twist-lock receptacle requires that it be twisted in order to connect properly. The male connector usually has curved prongs that plug into the receptacle and then are twisted to lock into place. When placed on top of another container, the auto twist-lock pops into the locked position. … Most ships have cells (vertical slots made by long metal rails) in the cargo holds, that do most of the work of keeping containers from sliding side-to-side.

Bridge Fitting

Bridge fittings are used to pull containers together when installing horizontal connectors. Bridge fittings can be used to clamp containers together when placed on the ground.
To safely connect shipping containers to each other, use these bridge fittings. They are designed to safely and securely connect empty or loaded shipping containers horizontally and are made to fit into container corner castings. Each container requires 4 bridge fittings for safe horizontal connections.

Stacking Pins

For safe vertical stacking of shipping containers, use these twist-lock stacking pins. The pins are designed to safely and securely stack empty or loaded shipping containers vertically, they feature a twist-lock action and are made to fit into container corner castings. Each container requires 4 stacking pins for safe vertical stacking.


Turnbuckles are used to tension a ship’s cargo container lashing. The securing device has two screw ends, of which one is welded to the ship’s deck with a lashing plate. The other screw end is attached to a lashing bar, connected with a container corner casting.
A turnbuckle, stretching screw or bottlescrew is a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems. It normally consists of two threaded eye bolts, one screwed into each end of a small metal frame, one with a left-hand thread and the other with a right-hand thread.
