EziTite® IBS Hydraulic Nut
EziTite® IBS Hydraulic Nut (Intermediate Boom Support)
Technofast manufactures the EziTite® IBS hydraulic nuts range as a permanent, boom-mounted solution engineered specifically for open-cut mining draglines.
These large mining assets rely on extensive booms supported by heavy wire ropes, which require balanced tensile loading to maintain structural integrity.
Our specialised intermediate boom support system allows maintenance technicians to monitor and adjust rope tension using a standard hydraulic pump, bypassing the repetitive lifting, installation, and removal of bulky manual tensioning equipment.
What Is an Intermediate Boom Support Hydraulic Nut?
An intermediate boom support hydraulic nut is a precision-engineered, high-tensile fastening device that permanently replaces original equipment hex nuts on dragline boom ropes. Operating via fluid dynamics (hydraulic oil), it shifts the labour-intensive process of mechanical rope adjustment into a controlled, safe, and efficient hydraulic process.
Traditional maintenance methods require crews to manually haul, lift, and mount heavy steel Tee bars and secondary jacks up at heights to adjust rope tension. The permanent, low-profile footprint of the EziTite® IBS simplifies the process. It optimises onsite labour profiles, significantly slashes shutdown maintenance downtime, and completely removes heavy manual handling hazards for site technicians.
Technical Component Configuration
Every EziTite® IBS assembly forms a self-contained tensioning system comprising:
- Nut Body: Screws directly onto the existing boom rope stud threads
- Piston: Houses the internal high-pressure fluid seals
- Spherical Washer: Compensates for joint face misalignment and serves as a locknut bridge
- Lock-Ring: Mechanically retains the tension when hydraulic pressure is vented
- High-Pressure Seals: Retains hydraulic fluid system integrity
- Socket Head Cap Screw: Used to deform the thread of the lockring to stop from releasing load when
dragline is in operatio - Locknut: Securely holds the active tension while the hydraulic nut returns to home position
- High-Pressure Inlet: 1/8” BSPP port with male hydraulic air fitting
Proven Case Study: Rio Tinto, Hunter Valley NSW Site
Dragline Boom Operation & Tensioning Sequence
Once permanently installed by hand threading each assembly flush against the structural platform face, executing a routine rope tension check follows a specific mechanical sequence:
- Hydraulic Coupling: Technicians attach a standard pump to the integrated 1/8” BSPP high-pressure inlet via the male quick-connect nipple fitting.
- Axial Elongation: Activating pump pressure drives the internal piston against the nut body, vertically stretching the support ropes along their direct axis to monitor or adjust the active load.
- Mechanical Load Locking: The threaded lock-ring is wound down by hand to mechanically secure the load flush against the spherical washer.
- Vibration Safeguard Activation: Technicians tighten the integrated socket head cap screw (SHCS) to intentionally deform the lock-ring thread slightly. This critical locking mechanism prevents the collar from spinning or releasing tension under the severe vibrations of an active dragline boom. Pump fluid pressure is then safely vented.
Engineering Specifications and Capabilities
The EziTite® IBS Hydraulic Tensioner is custom manufactured from high-tensile alloy or stainless steels to reliably withstand the severe industrial loads and harsh environments typical of open-cut mine sites.
| Application Feature | Mechanical Specification | Operational Impact |
|---|---|---|
| Direct Axial Loading | Eliminates thread friction by pulling along the stud axis rather than turning against resistance. | Minimises thread wear and protects the underlying asset from torsional stress. |
| Spherical Washer Joint Seating | Built-in self-correcting alignment base to compensate for misaligned bolts | Balances structural seating and prevents uneven loading across the face |
| Permanent Tool Mounting | Low-profile assembly that remains fixed to the boom structure indefinitely | Eliminates hauling bulky tooling up heights, cutting adjustment times down |
| Thread Lock Deformation (SHCS) | Integrated high-tensile socket head cap screw acting on the lock-ring | Deforms the thread slightly to prevent the nut from backing off under high vibration |

Frequently Asked Questions
How do EziTite® IBS hydraulic nuts prevent dragline boom failure?
Open-cut draglines feature long booms supported by a matrix of wire ropes. If rope loads become uneven, the boom structure experiences immense twisting stress. The EziTite® IBS provides precise, on-the-fly tension adjustment to ensure perfect load balancing across all support lines.
Can these hydraulic nuts remain permanently mounted in harsh environments?
Yes. The EziTite® IBS is specifically designed to remain permanently fixed to the boom structure. Built from rugged, heavy-duty alloy or stainless steels, it handles direct exposure to abrasive coal dust, moisture, and extreme cyclic operating loads.
Are custom thread profiles available for older or legacy draglines?
Absolutely. While we manufacture standard ranges to accommodate heavy industrial specifications, Technofast’s dedicated engineering facility regularly builds custom-designed variations with specialised thread pitches and tight geometric envelopes to match your exact mine asset footprint.
The assembly features an integrated socket head cap screw (SHCS) acting directly on the mechanical lock-ring. Once the target tension is reached, technicians tighten this high-tensile locking screw to intentionally deform the thread of the lock-ring slightly. This mechanical deformation prevents the collar from backing off, spinning, or shedding induced tensile load under the intense cyclic vibrations of an active dragline boom.
