It is absolutely critical in the evaluation of a legal case involving cranes, to determine what type crane is involved. The word "Crane" is a generic term that covers virtually anything that lifts with a hook, but each crane type is a whole different industry with different industry associations (which compile the industry product specifications), different governing specification and different OSHA requirements. As a matter of fact, some cranes don't even have hooks!

The universe of cranes can be reduced to seven groups.

  1. Electric Overhead Traveling Cranes
  2. Gantry Cranes
  3. Jib Cranes
  4. Mobile Cranes
  5. Tower/Construction Cranes
  6. Container Cranes
  7. Stacker Cranes

Each of this seven major categories have several sub-categories.

Using the proper vocabulary is especially hard in determining crane types. Like any industry, there is the proper nomenclature and then there's the slang the equipment has acquired over the years from the operator's.

Overhead Cranes:

Electric Overhead Traveling Cranes can also be called EOT Cranes, Overhead Crane, Bridge Crane, and Overhead Bridge Crane.

Gantry Cranes:

The term Engineered Gantry Cranes is usually reserved for the larger capacity and big ticket engineered cranes. Portable Gantry Cranes are the pre-engineered, "off the shelf" catalog products. RTG Gantry Cranes are the large rubber tired gantry cranes primarily used in shipping facilities.

Jib Cranes:

All jib cranes can be grouped in three types. Wall mounted jib cranes are a bit of a misnomer. They are actually mounted to vertical columns due the reaction loadings. Floor mounted jib cranes although mounted on the floor, are almost always anchored to an engineered footing. Lastly are wall traveling jib cranes, which as the name implies are attached to the exterior vertical surface and traverse the length of the building. These are very expensive and therefore equally rare.

Mobile Cranes:

These are rubber tired, over the road cranes. Mobile cranes can be divided into two main groups with countless sub-groups, Lattice Boom and Hydraulic Boom.

Tower/Construction Cranes:

These are the cranes commonly seen in larger cities, used to build new buildings. Tower/Construction cranes are also divided into two families, Fixed Tower Construction Cranes and Slewing Tower Construction Cranes.

Container Cranes:

These cranes are primarily used in two applications, 1) multi-modal transport facilities and 2) maritime container ports. To a much lesser extent, they are also used at industrial faculties to handle large fabrications such as tank fabrication facilities.

Stacker Cranes:

Stacker Cranes also come in primarily two varieties, 1) manual, pre-engineered, storage systems and 2) engineered AS/RS storage and retrieval stacker cranes.

The attackers are not necessarily strangers, but people we know.
