HARDWARE (GENERAL INFORMATION)

Shackles, hoists, rings, eyebolts, turnbuckles, clamps, rings and specialty items.

SHACKLES

NIS offers types of shackles designed for a variety of applications. Screw Pin Shackles are used when the connection must be changed frequently. Round Pin and Safety Pin Shackles are used when the shackle can be left in place. Safety Pin Shackles are made with a hex jam nut plus a cotter pin to prevent the nut from backing off. They should be used where safety requirements are of prime importance. Shackles meet Federal Specifications RRC-271D Type IV.

EYE BOLTS

Maximum load rating for eye bolts are based on a straight vertical lift in a gradually increasing manner. Angular lifts will significantly lower maximum loads and should be avoided whenever possible. If an angular lift is required, a properly seated shoulder pattern eye bolt must be used. A load should always be applied to eye bolts in the plane of the eye, not at some angle to this plane. Angular fits must never be more than a 45 degree pull.

SWIVEL HOIST RINGS

Swivel hoist rings are designed for lifting. They rotate and pivot to absorb any pitch, roll or sway of unbalanced loads. They will not yield to heavy side loads and help prevent the lifting hook from disengaging. Working Action: 360 degrees swivel and 180 degrees pivot.

STAR POINT EYE BOLT

The Star Point aligns to the direction of the pull, eliminating bending common with forged eye bolts. The body and bolt are 100% electromagnetic crack tested and working load limits are clearly marked in tons and lbs. on the body. Warning: the Star Point must be mounted on a flat surface to ensure proper seating and adjusted in the pulling direction. All fittings connected to the Star Point should be free moving.

SAFETY CLAMPS

Safety Clamps are designed to turn a single steel plate from horizontal to vertical to horizontal through a 180 degree arc. They lock open to facilitate loading and unloading the clamp, and lock closed to provide a more secure lift. Lifting capacities range from 2 to 20 tons and incorporate dual gripping cams, which provide increased grip on the load.

TURNBUCKLES

Turnbuckles allow for easy loosening and tensioning of chain and wire rope legs. They are available in eye and eye, hook and eye, jaw and eye, hook and jaw, hook and hook, and jaw and jaw styles. Turnbuckles meet performance requirements of ASTM specification F1145-92 Type 1 Grade 1. Maximum load ratings are based on straight vertical lift in a gradually increasing manner. Any deviations as angular lifts, shock loads, modification of the basic part, etc., will result in drastically reduced maximum loads.
