Rope Characteristics

Maxibraid Plus is a double-braided rope constructed of an inner load-bearing core of Ultra High Weight Molecular Polyethylene (UHMWPE). The polyester outer sleeve is slightly thicker than Ultrex Plus, which would provide more abrasion resistance in high-wear applications.

The UHMWPE core is coated with Yale’s Maxijacket coating prior to being over-braided, for added toughness. Yale has developed a special splice for larger sizes (3/4″ and larger), which incorporates a tucked core yet is covered as a conventional double braid. The advantage to this splice is no movement of the eye in service and a greatly shortened internal tail, making the rope more flexible and less prone to being damaged adjacent to the eye.

* Knots and abrupt bends significantly reduce the strength of all ropes and lower maximum working load.
** Working load is based on static or moderately dyanmic lifting/pulling operations. Instantaneous changes in load, up or down, in excess or 10% of the rope’s related working load constitute hazardous shock load and would void the normal working-load recommendation. Consult Yale Cordage for guidelines for working loads and the safe use of rope.

Rope Details

Fiber Type: UHMWPE from DSM Protective Materials, Polyester Sleeve
Elongation at WL: 0.6%
Elongation at Ult Break: 2.8 – 3.2%
Specific Gravity: 1.18 g/cc
Dielectric Strength: The maximum allowable leakage for clean, dry Maxibraid Plus is 100 micro-amperes when tested at 100kV per Yale Method 712-1701 Rev 1 “Routine Production Test.” Absorbed and entrained moisture or impurities will increase rope’s conductivity dramatically.
