FAQ

Both types of oblong links can be used for single leg or two leg  applications. The main difference is their physical size which provides versatility in fitment to either large crane hooks or factory hoists.
Yes, however strength of chain is derated by 25% for reeving.
PWB Anchor manufactures a range of chain in various grades and sizes. Chain manufactured by PWB Anchor is usually marked or stamped with PWB and/or its grade at regular link intervals.
PWB Anchor recommends the "light" oiling of Herc-Alloy 800 Chain Slings prior to prolonged storage. Suggested lubricant WD40.
Herc-Alloy 800 Chain and fittings should not be used in acidic or other corrosive environments. Please contact your nearest PWB Anchor branch for more information about the use of our chains in these types of environments.
Herc-Alloy 800 Chain is manufactured to exacting quality control standards and conforms to the mechanical properties of Grade T Chain specified in Australian Standard AS 2321.
Each manufacturer of chain may mark their chain in a different manner to distinguish its grade or type.
However, most rated lifting chains should at least have its grade marked at regular intervals.
No, do not weld Herc-Alloy 800 Chain or fittings to another material or try to join them. The heat applied during the welding process would be detrimental to the product and would adversely and significantly compromise its performance.
Herc-Alloy 800 Chain and fittings must never be hot dip galvanised, mechanically galvanised or electroplated, except by PWB Anchor. The heat that would transfer to the product during the galvanising or plating process would be significantly detrimental to the product.
Herc-Alloy Chain and fittings are heat treated under strict supervision during the production process. They do not require periodic heat treatment and must never be reheated by customers and end users.
Factory assembled chain slings are tested and tagged in accordance with AS 3775.
A Chain Sling should be inspected before each use to ensure it is free from damage and wear. It is important to check chain slings regularly, based on their frequency of use. Authorised PWB Anchor distributors are able to offer an inspection and testing service tailored to individual user's needs.
PWB Anchor can provide fully welded chain sling assemblies that have no mechanical joining devices. Prices and lead times are available upon request.
A reduction in the capacity of a chain, component or sling with a consequent revision of its working load limit (WWL), due to factors including how it is used, what it is used for, its surface finish and the work environment.
The Clevis Self-Lock Hook will lock itself when the load is engaged. The Clevis Safety Latch Hook is a general latch (spring loaded).
Yes, providing the sling is tagged with its WLL, ensure you know what the load to be towed is and that you never exceed the WLL under any circumstances. Once used as a towing chain, the sling should never be used for lifting.
Where temperatures are likely to be higher than 200ºC reductions in the working load limits of Herc-Alloy 800 Chain Slings should be applied.

Hazardous substances outlined in the restriction of hazardous substances (ROHS) directive are not used.
A Chain Block is a manual lifting device. A Chain Hoist is a power operated lifting device.
The IP rating is a weather protection rating. IP means ingress protection and is shown, for example, as IP55. The first number relates to dust protection. 5 means the unit is sealed to prevent sufficient dust entering the hoist which could interfere with normal operation. The second number relates to water ingress. A rating of 5 stipulates the hoist is protected against low pressure water jets from all directions.
Chain can not be joined together to extend the lift of any hoisting product. To satisfy this requirement, a new length of chain must be purchased and fitted by a competent person. It then needs to be tested to ensure the product has been assembled correctly and re-certified.
PWB Anchor can recommend accredited service agents throughout Australia.
Yes it is, allowing the motor power to be disconnected from the main power supply in any emergency.
No, due to the mechanics and lubricants in the hoist, this is not a recommended practice. However, PWB Anchor has a range of CM Lodestar or Prostar motors that are specifically designed for the entertainment industry that can be used in the inverted position.
Yes. ER2 Electric Hoists are available in many different lift heights to suit your requirements.
Yes, ER2 Hoists that are rated IP55. This means they have protection from direct jet spray and dust particles. Also they have a strong epoxy coated painted body and the load chain is Nickel-plated, which is corrosion and abrasion resistant. However to better protect the hoist in external applications a cover is recommended. 
These come with one pendant that controls the entire assembly.

Trailer Safety Chain, unlike Proof Coil Chain must go through extra processes and testing to ensure it complies with the requirements of Australian Standard 4177.4 - 'Caravan and light trailer towing components Part 4: Safety chains up to 3500kg capacity'.
In the event of an accident, if any components do not comply with Australian Design rule 62/01 - Mechanical connections between vehicles, liability lawsuits are possible.
Trailers above 3.5 tonnes Aggregate Trailer Mass are subject to comply with other regulations and may incorporate chain from Australian Standard, AS 2321 for 'Short Link Chain for Lifting Purposes.' Which encompasses a range of Grade 80 (Herc-Alloy) Chain.
There are minimal practical applications for the 6mm size. It also difficult to stamp, which is a requirement of Australian Standard 4177.4.
The most common 'box-trailers' up to 3.5 tonnes, utilise the 8mm, 10mm & 13mm Trailer Safety Chain in accordance with the appropriate Australian Design Rules.
Trailer Safety Chain is designed in sizes according to the capacities required on the Aggregate Trailer Mass (ATM). 8mm is for trailers up to 1.6 tonnes ATM (stamped 'PWB4177-16'). 10mm is for trailers up to 2.5 tonnes ATM (stamped 'PWB 4177-25'). 13mm is for trailers up to 3.5 tonnes ATM (stamped 'PWB 4177-35').
Self-Colour (natural steel finish) chain can be welded directly on to the drawbar and the trailer may then be painted or galvanised.

Generally, a 2-to-1 ratio is appropriate (1100 lb winch for a 2200 lb boat), but there are factors to consider. When a well-equipped and maintained roller trailer is used and the ramp setup is such that it allows the boat to float partway onto the trailer, the ratio can be stretched to 3-to-1. On the other hand, if the ramp is steep, a carpeted bunk trailer is used, or conditions require the winch to pull the boat a longer distance, the ratio should be reduced to 1-to-1.

A self-locking winch should always be used in any situation that involves vertical lifting. DLB-series or B-series brake winches, or a worm gear winch should be used to avoid the potential of a load free-wheeling out of control.
No. The “B” suffix means that the winch comes equipped with a hand brake that must be operated manually. It makes it easier to control the winch while releasing a load. It does not lock the load into place like a brake winch does.
How many handle revolutions it takes to turn the spool once. A gear ratio of 4:1 means that it takes four complete turns of the handle to turn the spool 360 degrees.
Two drive shafts are used on a two-speed winch, to allow a choice between “low” and “high” gears. Lower gear would be used in steep or otherwise difficult situations, while the higher gear would result in faster operation. To change gears, the handle is removed and installed on the other drive shaft (no tools required).
The term “two-way ratchet” is often misunderstood. All it means is that, prior to using the winch the first time, the user can choose which direction to wind the line onto the reel. Once that’s done, the extra ratchet position serves no purpose. Because of this, we developed and patented a reversible ratchet that is easier to use, but performs the same function. The ratchet pawl is installed with the assumption that cable will wind off the top of the reel (which is true in almost all cases), but it can be easily removed, turned around, and re-installed to allow cable to come off the bottom if needed.
Yes. A brake winch is a good choice and adds an extra element of safety that many people like. There are also models available with a feature for quickly pulling line from the winch (DLB805A, DLB1205A and DLB1505A), which speeds the boat retrieval process.
A brake winch or worm gear winch are well suited for this application; however, once in position the load must be secured by additional safety lines. 
No, these types of high strength synthetic ropes are not recommended for D-L winches. These ropes are extremely slippery and pose a high risk of severely damaging the winch's reel and ultimately the winch as a whole. 
This is actually normal. When running the winch in the power out direction the brake mechanism gets very hot and burns off any oil film left from the assembly operation. As soon as the oil film is gone, the smoke will stop. As long as you observe the maximum run time for your winch, it is not a cause for concern.
The motor should cool 5 minutes for each 1 minute of run time.
Due to the complex manufacturing process and availability of materials, PWB Anchor has decided not to pursue this product line.
