Slings



With the use of Emcocables manufactured Improved Plow Steel (high resistance), a stronger and safer union, and rods of aluminum or steel placed under high pressure, Emcocables is able to manufacture slings of the highest international standards.

Emcocables’ slings are widely used in every kind of industry: maritime, oil, mining, and other fields in which movement, rotation, or elevation of a cargo load is required. The necessity for slings is almost permanent for any application.

Their definition, components, and advantages

A sling is an apparatus designed to connect to a cargo load that needs to be elevated, moved, or rotated in conjunction with an element such as a crane’s hook.

The sling is the tool most used around the world for the movement and maneuvering of all kinds of cargo for the following reasons:

  1. Technically designed for whatever the sling will be used
  2. Economical
  3. Long life
  4. Ease and security of movement
  5. Cargo protection

Regardless, as is the case with any machine, a sling requires care and should be inspected in order to determine that it is able to carry out the movements that are asked from it.

Elevation Capacity

The rated capacity of a sling is the maximum load (in tons) for which it is designed to operate under normal conditions. This is based on the break load of cable, the design factor, number of branches, type of sling (simple, basket, or traveling), load angle, and diameter of the curve around which the sling is bent.

Number of Branches

  1. Single Branch Slings
    1. A great amount of single branch slings can be produced by adding different amounts and kinds of elements. The single branch sling is the basic sling. It can be used “vertically” or “simply,” which means it is wrapped around the cargo in the shape of a basket. Also, the “traveling” method can be used.
  2. Multiple Branch Slings
    1. Many cargo loads cannot be manipulated with a single branch sling; this is why over time multiple branch slings have been developed. In their simplest form, the slings consist of two, three, or four single branch slings connected at their elevation extremes to a common accessory (elliptic ring or in the shape of pear).
  3. Endless Slings
    1. These slings are produced with normal configurations for very special cases of cargo maneuvering.
