Chain Slings

Adjustable chain slings are suitable for handling odd-shaped or hard-to-position loads. Alloy steel construction ensures strength, lightness, and rust resistance. Ideal for use where headroom is limited, with portable hydraulic cranes, and balanced or unbalanced loads. 

Lift Arts make adjustable leg slings are available in different configurations of single, double triple or quadruple bridles.

An adjustable sling features additional shortener fittings (A Chain Shortener device or Grab Hook) that are attached to the master link. These allow the operator to adjust the length of the chain legs as needed, without compromising lifting strength and working load limit.

Compensation Drawing

• The suitable temperature range of the product is -25°C - 50°C.
• When you are ready to install the compensation chain, it is necessary to straighten out the chain first, or it will affect the running effect and service life.
• The centre line of the damping device and the Suspension point should be in the same perpendicular line in order to
• reduce the friction between the compensation chain and the damping device.
• The minimum distance is one meter between the installation point of the damping device and the curve
• bottom of the compensation chain otherwise it may cause accidents.

Alloy Chain Slings have the advantage of being durable, extremely flexible and its length can be made adjustable.  These slings employing alloy chain are resistant against a load's sharp edges that can be abrading to other softer sling materials. Alloy chain slings are the most durable type of sling and is easily repaired in the event of damage.  Alloy chain slings are ideal for harsh environments.  An alloy chain sling will tolerate a wide range of temperature; however, compared to other types of slings, it is relatively expensive and, depending upon the grade of alloy chain used, relatively heavy.  

Lift Arts make alloy chain slings are available in single, double, triple, quad, and Endless configurations.  We offer a wide variety of bottom fitting options for welded alloy chain slings like Eye Hook, Clevis Hook, Eye Self Locking hook, Oblong Link, Shackles etc. we are manufacturing these welded chain slings in accordance with IS:2760-1980 standard.

SINGLE BRANCH SLINGS

Single branch slings shall have a working load limit equal to that of the Chain used in construction

MULTI-BRANCH SLINGS

Multi-branch slings shall be rated at a uniform working load limit for any angle between branches of 0-90° (0-45° to the vertical) or additionally at a uniform working load limit for any angle between branches of 90-120° (45-60° to the vertical).

UNIFORM LOAD METHOD  

• A) Double branch slings:
• For all angles between branches from 0-90° (0-45° to the vertical)
• WLL= 1.4 X WLL of a single branch made of similar chain
• When additionally marked for a angle between branches of 90-120° (45-60° to the vertical)
• WLL= 1 X WLL of a single branch made of similar chain
• B) Three & Four branch slings:
• For all angles between branches from 0-90° (0-45° to the vertical)
• WLL= 2.1 X WLL of a single branch made of similar chain
• When additionally marked for a angle between branches of 90-120° (45-60° to the vertical)
• WLL= 1.5 X WLL of a single branch made of similar chain
• Note:- in case 3 branch sling the angle between branches shall be taken as twice the angle to the vertical and in 4 branch slings the angle between branches shall be that between diagonally opposite branches

Chain slings offer years of service and exceptional versatility, as well as immense adjustability. Lift Arts make weldless chain slings are available in many different types, and slings can be sized to fit different lifts by using fittings like chain shorter that allow for adjustment. Weldless chain slings are assembled by using forged mechanical connecting devices like chain connectors etc.

Grade T(8) Alloy Steel Chain is manufactured specifically for use in chain slings for lifting purposes. The chain is heat treated for tensile strength and resistance to wear whilst also allowing for shock absorption.

Chain slings are used primarily for overhead lifting and are generally used in conjunction with a crane or some type of lifting device. Standard sling configurations consist of chain branches, which have master link or ring at top end with some type of attachment, usually a hook, attached to the opposite end. Our Grade T chain slings are recommended for use in an industrial environment where flexibility, strength, resistance and long life are required
