A chain block is a manual lifting device. A chain hoist is a power operated lifting device.

What does the IP rating for an electric hoist refer to?

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.

Can I add chain to extend the height of lift of a hoist?

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.

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

Do you get 2 pendants with electric hoist and motorised trolley combinations?

These come with one pendant that controls the entire assembly.

What is the difference between a Bow Shackle and a Dee Shackle?

The only difference is in the shape of the Shackle, but they are all marked with their rated capacity.

What is the difference between a Safety Pin and a Screw Pin Shackle?

The difference between these Shackles is in the pin itself. A safety pin is secured by a nut and cotter pin and the screw pin is attached by being screwed into the opposing thread of the body.

What are the markings on chains?

However, most rated lifting chains should at least have its grade marked at regular intervals.

What is different about Trailer Safety Chain?

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'.

What are the ramifications of not using Trailer Safety Chain?

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.

Why does Trailer Safety Chain come in 8, 10 and 13mm sizes?

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.

What are the different sizes of Trailer Safety Chain used for?

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').

What is the difference between Self-Colour TSC and Galvanised TSC?

Self-Colour (natural steel finish) chain can be welded directly on to the drawbar and the trailer may then be painted or galvanised.

Differences within the ENDO brand of spring balancers are in the body type and stroke length.

What is the difference between a snatch block and a sheave block?

A snatch block has a side gate to allow easy fitting or removal of rope. A sheave block requires the rope to be fed through over the sheave.

Can I replace the sheave in my Sheave Block?

My strongarm winch has quit working. Where can I have it fixed?

Please contact KITO PWB for assistance.

How do I know what size winch is needed for my boat?

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.

Is it necessary to have a brake winch for vertical lifting, or will a ratchet winch work?

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.

Does a “B” at the end of the model number (example: DL1800AB) mean it’s a brake winch?

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.

What does “gear ratio” mean?

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.

What does “two-speed” winch mean?

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).

What is a “two-way” ratchet, and why don’t I find any on your website?

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.

Can a brake winch be used on a boat trailer?

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.

I want to use a brake winch to raise my canoe or bicycle up to the ceiling of my garage and hold it there when I’m not using it. Is this okay?

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.

Can I install and use high strength synthetic rope (Dyneema, Sampson, Master Pull, Puget Sound, etc.) on my D-L winch?

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.

The first time I used my StrongArm® electric winch, it smoked and became very hot. Why would this happen with a new winch?

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.

How long does an electric winch have to cool off after use?

The motor should cool 5 minutes for each 1 minute of run time.

Are custom bolt lengths available for the Swivel Lifting Point?

The bolts supplied with the Elongated Swivel Lifting Point can be cut down to suit the specific length requirements.
