Trailer Safety Chains and Shackles

2 years ago No comments

At HES we are often asked by our customers about the legal requirements for trailers of various sorts, whether boat trailers, box trailers, machinery trailers, or caravan.

People have been fined by RMS for the wrong shackle or an 'unstamped' safety chain, so it's important to use a safety chain that is certified for this use.

After checking several documents, including Australian Standards and Roads and Maritime Services (RMS) NSW 'Light Trailer and Caravan Pre-delivery Checklist', we can recommend the following attachment details;

Agg Trailer Mass

Minimum Chain Size

No. of Chains

Minimum Shackle Diameter

Up to 1000 Kgs




1001-1600 Kgs




1601-2500 Kgs




2501-4500 Kgs




4501-7500 Kgs




Aggregate Trailer Mass is the total mass of the laden trailer when carrying the maximum load as recommended by the manufacturer. This will be stamped on a data plate and shown in kilograms.

Safety Chains must be stamped AS4177.4 on the links.

Shackles can be either dee-type or bow type, but must be rated and stamped with WLL.

These regulations apply to NSW. If you live outside this region, you'll have to check your local regulations. It's also important to note that trailers manufactured prior to 2006 may be exempt from these regulations.

At HES NSW we carry a range of fully approved safety chains and shackles to suit your trailer. We can provide cut lengths and select the correct shackles to fit your trailer. Contact us today to discuss your needs.

Choosing the Correct Winch for Towing a Boat or Caravan

2 years ago 2 comments

At HES we are regularly asked about winches to pull your toys into the shed or garage. The most common query we get is something like this: "My boat weighs 2 tonnes, so do I need a 2 tonne winch?"

Winches are generally rated by their line pull capacity, meaning the winch is capable of lifting a dead weight to that capacity. Your boat may weigh 2 tonnes, but if you are just pulling it into the garage, you are not lifting it as a dead weight.

When putting a boat or caravan in the garage, it will usually be on a trailer or a carriage that transfers much of the weight to the ground. This means that a 2 tonne winch is probably overkill.

To calculate the right winch for your needs, these are the factors that we need to consider:

  1. The incline angle of the ramp: The steeper the ramp the more line pull capacity is required.
  2. The weight of boat, trailer and any other inclusions such as fuel, motor etc.
  3. The friction caused by your trailer or carriage. Is it on wheels? Are they solid wheels or rubber tyres? The less friction created, the less line pull required.
  4. The distance from the water to the shed. Winches have multi-layered drums for the wire rope. When used on the outer layers, the line pull is less powerful but the speed is greater. On the bottom layer, the line pull is greater but the speed is slower. A longer pull will generally need a stronger winch.
  5. Power Source. What power source is available, 240v or 415v?
  6. Operating Position. If you need to be at the boat, a remote control may be required. If you can operate the winch from the shed, a simple pendant control or on/off switch may be best. Here is one important safety tip: never stand behind the winch while it's working; if it fails, you could be seriously injured.
  7. Electric or Hand Winch? Using a hand winch is usually a lower cost option, but they are slower than powered winches and require greater physical effort. If you use an electric winch it is also a good option to get a fire extinguiher on your boat or trailer.
  8. Shed Size and Foundations. Will the winch fit in your shed? Are the foundations capable of securing your winch?

To allow us to recommend the best winch for you, we enter all the available information into our Winch Load Calculation Tool, which uses an engineer-designed formula for a quick result.

Here at HES, we sell a complete range of quality winches for multiple applications and can offer installation, servicing and repairs via our experienced service team. HES Winches are the manufacturers of the superior quality Oz Signature Series slipway winch and OzWinch range, with models to suit most applications. We also distribute other major brands including Jarrett, Atlantic, Titan, Warn, Pacific and many others.

With branches or distributors across Australia, we are never far away. If you are in need of help buying or repairing a winch, please contact us today.

Height Safety Training for Theatre, NIDA

2 years ago No comments

For many years, HES NSW has been assisting our customers with targeted, industry-specific training related to working at heights. One of our customers whom we have worked with in this way is Sydney based NIDA, the National Institute of Dramatic Art.

NIDA is Australia's leading institute for education and training in the dramatic arts.

Recently NIDA's Peter Savage, Associate Lecturer and Course Coordinator for Production, contacted HES NSW's Peter Allman and arranged for a group of 13 international students to be trained in Working Safely at Heights. This training is a requirement for certain courses at NIDA and increases safety, especially for individuals who work in lighting and the upper areas of theatres.

We contacted Stephanie Kells, Training Administrator at our training partner Spanset Australia who sent trainer Jon McQuade to NIDA at Kensington on February 15th. Spanset is a market leader in Height Safety supply and training and this course is nationally recognised and accredited.

The course was held successfully on the 15th. John reports that the students were enthusiastic and the training went very well, with all attendees passing with flying colours.

NIDA is a great example of an employer taking safety seriously. All employers have a duty of care to provide training and instruction for High Risk activities. HES NSW is able to assist our customers fulfil these obligations. Please contact us today if you are interested in learning more about training opportunities.

●Periodic Inspection Guide

●Grade V (100) WLL'S – UP TO 32mm now included

●Leg Length Tolerances have changed

●New Duration Guide – for corner loading

●Proof testing - each sling shall be proof tested after manufacture, when damaged and when missing tags

●Maximum reeving angle is now 60 degrees

●Self Locking Hook Inspection – guidelines on clearance between hook and latch

●Safety Hooks – requirements on spring loaded latches.
