HARKEN SOLUTIONS for Commercial Marine

Harken’s strong, reliable products make working in adverse conditions safer and easier. From pulleys with 95-ton break loads that weigh just 22.5 kg (48.5 lb) for single-operator handling, to corrosion-resistant rail and cars for transom recovery. See our product range to find out how Harken equipment can assist in your applications.

Tight Radius System (TR31)
Tight Radius System (TR31)

WORK SECURELY AND SAFELY

The Tight Radius rail-and-trolley system is designed to work as an adjustable anchorage point for fall restraint on marine vessels.

Rails are composed of straight and sections curved sections that change direction in both horizontal and vertical planes, allowing trolleys to run exceptionally smoothly around very tight radii and joints.

The system is independantly tested and conforms to EN795.2012 B/D

How does it work?

The TR31 continuous rail and trolley system allows a fully-harnessed crew member, safely tethered to the trolley, to move freely along the rail during inspection and maintenance, or when assisting in pilot transfer.

Rails can be either surface or stanchion mounted and are designed so the user never has to unhook and rehook the tether as he moves around the deck.

Part No. 441.627

TESTED TO EN795:2012 CLASS A

Uses

The 441.627 stainless steel round anchorage point is designed to be permanently installed on a structure so that an anchor device, or personal protective equipment can be attached to it, facilitating safe working at height.

The padeye is appropriate for single-person use with an energy absorber to EN 355. It is large enough to allow articulation, will accommodate karabiners, and is cost effective.

  • Please note – actual product will have a serial number and maximum load etched on.

LOW-FRICTION LINEAR MOVEMENT                    Trolley Information  Rail Information

Harken trolley and rail systems provide a simple low-maintenance way to move loads smoothly. Trolleys feature recirculating ball bearings housed in strong, lightweight, corrosion-resistant aluminum for dependable, low-friction linear travel.

low-precision

Low friction, smooth rolling
Harken rails and trolleys provide a low-friction rolling solution under both compression and tension loads.

Torlon® or Delrin® ball bearings reduce friction to move loads easily, and require no lubrication. Wire retaining clips and composite corner keepers keep ball bearings captive, allowing trolleys to be easily removed for maintenance.

Harken trolleys are designed with an open-ball race for easy maintenance. The rail can be bent to various radiuses, allowing the trolley to run freely.

compression-and-tension

Curved rail
Rails can be bent to suit various applications. Minor bends can be made when the rail is installed.

If the rail requires greater bend, Harken can provide horizontal, vertical, or compound curves to specification.

Rib Seat Track System
Rib Seat Track System

A BETTER RAIL SYSTEM FOR MOUNTING SHOCK MITIGATION SEATS

This system is specifically designed for the marine environment, giving you a flexible cockpit layout with fast, hassle-free reconfiguration.

We tested this system over 19.5 kN to meet HSC regulations.

How does it work? 

Seats are mounted on four trolleys that run on parallel rails. Two of the trolleys have pinstops that locate into the holes in the rails. Two trolleys are free sliding.

To adjust the trolley location, simply raise the two pinstops and slide to new location.

Trolley design

  • Strong – tested to over 20 kN
  • Adaptable – can be fitted to dive tank racks, weapons racks,deck boxes etc.
  • Compact – only 33 mm wide; minimum intrusion on cockpit sole
  • Black hardcoat-anodized; maximum corrosion resistance

Rail design

  • High strength 6061-T6 aluminum low-profile rail—only 22 mm
  • Hardcoat-anodized for maximum protection
  • 33 mm pinstop hole spacing for maximum flexibility in seat spacing
  • Countersunk M5 fasteners for flush fit.
  • Underside of track recess for mastic sealant.

Installation and maintenance

Flush clean with fresh water and mild detergent. To reduce friction further, use McLube® high-performance dry lubricant. Do not use oils or greases.

For added protection against corrosion, Harken UK recommends using Tef-Gel® corrosion eliminator on the fasteners when installing the rail.

IN11118.563 – Cable ∅ – 17 mm

 

LIGHT ENOUGH TO ALIGN TO THE LOAD

Harken Oceanic cable blocks are used on research vessels to safely lead data cables and towed objects overboard. At only 19.3 kg (42.5 lb), the 500 mm (19.7″) sheave diameter block is light enough to align to the load, optimizing cable tracking.

Oceanographic research
The Oceanic cable block is used by Woods Hole Oceanographic Institute, University of Rhode Island (USA), and University of Alaska – Fairbanks oceanographic research departments, as well as many other research organizations.

Maintenance is easy
Flushing the block with fresh water after use will keep the dry-running bearings free rolling. If further maintenance is required, one hex wrench is all you need for disassembly. All the bearings are captive, so no need to worry about losing parts.

Oceanic block durability

Durability
Sideplates are constructed of hardcoat-anodized 6061-T6 aluminum for strength, durability, and corrosion resistance. They are PTFE-coated for a smooth surface.

Oceanic block bearings

Bearings
Delrin® roller bearings are housed in a center cage to keep them parallel for low-friction efficiency. The large diameter bearing cage reduces friction and spreads the load. Captive Torlon® ball bearings handle sideloads.


Oceanic block large diameter sheave

Large diameter sheave 
The block’s open center helps move the center of gravity toward the shackle, improving the block’s ability to align with the load. The sheave’s groove detailing can be designed to suit specific data cable diameters.

Oceanic block Design

Design

The block’s wide throat allows passage of data cable terminals. The sheave’s durable, lightweight Nylatron® material has high mechanical stiffness, resists static electricity, and has excellent wear resistance. Plastic isolators and helicoils are used to minimize corrosion between aluminum and stainless steel. The Oceanic cable block is UNOLS
compliant.

Harken purchase systems increase operation strength, providing low-friction pulling power in a wide variety of pulling/lifting operations. Systems can be used on their own, or easily combined with an existing system for tensioning, deviation, or casualty transfer. Purchase systems come fully rigged with tamper-evident termination.

Simple to use in load-assist applications
Harken purchase systems are used by emergency services and rescue personnel to help transfer loads and individuals from working ropes to alternates. The systems are also used to transfer loads in deviation, and to take the load when lifting inanimate objects.

Maintenance is easy
To clean, simply flush pulleys with fresh water. As with all equipment, check regularly to make sure it is in good working order. Check rope for chafe and wear. Make sure tamper-evident seals are intact.

THE ULTIMATE IN POWER-TO-WEIGHT EFFICIENCY

SBL (strong but light) Snatch pulleys maximize the benefits of fiber rope within a safer, more ergonomic working environment. Weighing less than 25% of comparable pulleys, they make light work of rigging and deployment. The  hardcoat-anodized sheaves run on high-efficiency composite bearings, reducing rope wear.

Simple to use and ideal for diverse applications
SBL Snatch pulleys can be used for towing, mooring, pulling, and lifting across many industries.

  • Utilities
  • Commercial rigging
  • Offshore
  • Renewables
  • Commercial marine
  • Transport
  • Salvage
  • Military

Maintainence is easy
The simple construction requires no lubrication. Simply flush with fresh water to keep your SBL Snatch pulley free rolling.

SBL design

Design
Side-opening plates allow the pulleys to be rigged easily. The soft attachment system eliminates heavy swivels and shackles.

SBL materials

Materials
Sideplates are hardcoat-anodized, UV-stabilized 6061-T6 aluminum for maximum protection. Sheaves run smoothly and maintain efficiency at high loads using PTFE-coated ULC bearing technology.

SBL materials

Fiber Rope
Snatch pulleys are used with fiber rope up to 25 mm (1″) in diameter. Smooth surfaces and chafe-free design minimize wear.
