Heavy Duty Hoisting Eye Bolts – 360° Rotating Industrial Lifting Bolts

Our high-quality hinged units are designed for full 360° rotation, providing smooth and flexible movement in any direction. Each unit features a hoisting snap link that must be installed in the direction of the load for maximum safety, remaining free to move without being supported at an angle. These units are engineered to handle full loads in all directions, ensuring reliable performance in demanding lifting and hoisting applications. The outer and inner hexagonal bolts are 100% crack-checked and compatible with standard tools, making installation simple and secure. Ideal for construction, manufacturing, and material handling industries, these hinged units offer durability, safety, and ease of use, making them a dependable choice for heavy-duty operations.

• Can handle full loads in all directions

• Easy-to-use bolts for all tools

• Safety-tested for heavy-duty work

Safety Tips for Load Handling

Never rotate the hinged unit while it is carrying a load.
These units are built to handle full loads safely in any direction.

Strong and Reliable Bolts

All bolts are checked for cracks and are made with hex heads for easy use with standard tools.

• F₁ (Axial Force):
  This is the main lifting capacity of the bolt. It measures how much weight the bolt can safely carry when the load is applied straight along its axis.

  F₂ (Transverse Force):
  This is the maximum side load or shear force the bolt can handle. Side loads are much weaker than vertical loads, so the safe capacity is lower than F₁.

  a, d (Internal Eye Dimensions):
  These measurements define the opening inside the eye of the bolt. They determine the size of hooks, rings, or other rigging equipment that can be attached.

  b (Material Cross-Section):
  This is the thickness of the bolt material just above the eye. It shows how strong the bolt is at its narrowest point.

  c, d₂ (Thread Size and Engagement Length):
  These define the thread dimensions and how much of the bolt is threaded. This ensures proper fastening and secure attachment.

  e (Handling Flat Width):
  This is the distance across the flat sides of the hexagonal bolt head. It shows what size wrench or tool is needed to tighten or loosen the bolt.

Load Rating Explanation

The load capacity of the lifting bolt is shown using two force directions. F₁ represents the main vertical lifting force applied along the axis of the bolt. F₂ represents the side or transverse force that acts when the load pulls from the side. These forces are often shown with color-coded arrows to help users clearly understand how the load acts on the bolt during lifting.

360° Swivel Function

The lifting unit is designed to rotate 360 degrees, allowing the lifting ring to move freely in any direction. This swivel feature helps the bolt align with the load automatically and reduces stress during lifting. Inside the unit, a bearing mechanism allows smooth rotation even when the bolt is under load.

Dimensional Explanation

All important dimensions of the lifting bolt are clearly marked to help users understand the size and installation requirements:

• a – Internal eye opening used for hooks or lifting accessories.

• b – Minimum material thickness above the eye, which contributes to strength.

• c – Thread engagement length used to secure the bolt into the component.

• d – Outer width across the flats of the bolt head.

• d₂ – Diameter of the threaded shank that goes into the mounting hole.

• e / e₁ – Width across the hexagonal flats used for wrench or tool tightening.
