An Eagle (Lasher) Returns to the Nest

We took in an Eagle aerial cable lasher last week for repairs. “It wasn’t running smoothly anymore and it needed a few adjustments,” they said.

As it turns out, this lasher is serial number E00109 – built in January 2007 and delivered to the customer. In the intervening 5 years, it looks like it’s run a few thousand miles and gotten into a couple fights!

The drive wheels had grooves worn into the track from the lashing wire, and they weren’t turning well. The drag from the wheels was loading up the gearbox, so we overhauled that too. And we replaced a couple worn shafts and rollers…

After a bit of work, Eagle lasher E00109 is back on the wing and lashing our fiber optic test cable smoothly!

It’s that time of year – maintenance time! Time to have a look at your gear and decide if it’s ready for the coming season, or if you need to put some work into it now. These days, most people are leaning towards repairing the gear they have and making it last a little longer.

DCD Design and our distributor network are here to help assess your gear and get it in for the necessary repairs, whether it’s overhead cable lashing, underground cable installation or horizontal directional drilling/boring.

Yule Love Our Duckt Pullers!

Careful, there’s a two-pun limit over the holiday season! DCD’s December promotion has kicked off, with sale pricing available on the 00650 Deluxe Sealed Duct Pullers. New this season, we’ve updated the Puller Jaws to fit 3 o-rings for redundancy in service.

To go with that, there’s a new instructional video on DCD Design’s Youtube channel, showing you how to service the Pullers and replace o-rings. Check the replacement chart to see which o-rings fit your Duct Puller.

If you subscribe to our monthly newsletter, you already knew that. If you haven’t subscribed- why not?? Enter your email address here and keep up with all our news. (Or add a comment to the effect here on the blog and we’ll add you to the newsletters.) Catalog requests can click here.

Turkey Time?


The DCD Sales Desk has had a run on Duct Rodders this week! Taking advantage of our monthly promotion before the long weekend?

DCD Duct Rodders – all of them! – are on sale in November and with Thanksgiving approaching fast, that means there’s only a few days left to get an order in.

We’ve produced a few videos for the Duct Rodders; most recently, a quick instruction on re-spooling the rod into the cage. The pultruded fiberglass rod is strong and flexible, but you need to feed it into the compact reel cage smoothly to ensure the Rodder lasts.

Here’s a complete playlist of the DCD Duct Rodder videos – putting all our reference videos in one place.

DCD Design will be open Thanksgiving Day so if you need something, let us know. Otherwise, have a great long weekend!

On the Road and Coming to Your (Web) Site!

Doctor Duckt has been on the road recently, presenting an introduction to Social Media and Business Resources on the Web to the Melfred Borzall distributor network. I talked about websites, Google searches, Youtube, Facebook, and Analytics – and I’m going to review some of the highlights in the next few weeks.

WEBSITES
Websites have become a part of the business landscape in the past ten years, as much as the logo on your truck and the sign on your building. You need to put some effort into maintaining these public images, but websites don’t need to be expensive.

To succeed, websites need to give your customers the information they’re looking for. Whether it’s the brands you carry, your location, or the person to talk to when the customer gets in touch.

Start simple: with a web address, a logo (or even a photo of your location!), and a contact number. But start somewhere. (Hire a student! 5 hours work should give you a toehold on the internet.)

KEYWORDS
Even the most simple website can be successful, if it can be found by Google, Yahoo or Bing. Give your web address good keywords and some links to related products.

Keywords are the search terms that a typical customer will enter into Google when they start looking for your product. Provide as many terms and descriptions as you can think of! Include the local variants and wrong names that customers might use – it helps.

LINKS

Connecting with another website in the industry is a good way to get noticed. Links that go both ways strengthens the relationship and improves your search rankings too.

Enough for now. Here’s a few photos from the road. And thanks again to Melfred Borzall for inviting me down to Santa Maria for a great visit!

The Right Wire Mesh Grip – Pulling vs. Support Grips

Pulling grips and support grips are intended for very different applications. Pulling grips are built of much heavier, stiffer and stronger wire for an equal diameter, than support grips, because they’re moving. A support grip carries a (mostly) static load.

The medium-duty 00670 grips, for example, fit over the end of the cable being pulled, “capping it” while you’re pulling. It will have to come off once the cable end comes out the other side. Support grips are woven to grip the mid-span of suspended cables, and open-ended.

Support grips are usually much lighter weight than equivalent pulling grips – they’re built to support the dead load of the cable, rather than the tensile loads experienced when pulling the cable into place. (A few hundred pounds of cable versus a couple thousand pounds of tension.)

For example, a 00670 series grip for 1-1/2″ cable has a SWL of 2760lb (5x SF). A support grip for the same size cable would support 300-400lb (different SF though = 10x).

I would suggest a pulling grip to move the cable into position, then a support grip to permanently locate it. If you’re in an exposed environment, then specially ordering the stainless option will be strongly advised too.

For more information, see our catalog pages on the website.

Get a POWER-Grip

DCD Design’s Power-Grips and Swivel-Grips are on special through February! Here’s a previous posting to highlight the Grips and see our new video on Youtube, detailing the assembly procedure.

These Grips are designed to make cable installation easy and secure. The re-useable Grips are sized to fit electrical cable from 1/0 through 2000MCM and really shine for the larger cables, where the pulling tension will approach the cable manufacturer’s allowance.

Assembly of the Power-Grip to the electrical cable is quick and easy: cut back the insulation to bare the conductor; mount the Threaded Cone Nut to suit the conductor size; screw in the Tapered Insert; and mount the preferred attachment Body. You select which Body suits your connections: the Lug, Clevis or Swivel Bodies share common threads to quickly mix and match.

The Power-Grip locks onto the conductor strands and the harder you pull, the tighter your Grip! When you’ve completed your pull, cut away the portion of the cable conductor deformed inside the Power-Grip and that’s it. You’re ready to re-use the Grip for the next conductor.

Another Good Idea: Making Dewatering Easier

We took a call from a customer a few days ago. His 00650-150 puller wasn’t broken, but neither was it gripping like it used to. As it turns out, Gary Fors and Designed Groundwater Services were applying our Sealed Duct Puller in a manner we’d never considered before! I’ll let Gary explain:

“Yes, we use your pullers often and rely on them as a way to get the decommissioning of our dewatering wellpoints completed properly.

“In 2008, Washington State changed the law on “water well” decommissioning. Previously it was fine to just pour bentonite or hole plug down the wells. Then the law changed and we had to find a way to pull every wellpoint out of the ground from depths of up to 25 feet.

“This proved almost impossible with traditional methods like chokers or nylon straps because they either shattered the plastic or slipped off. So, we went to Ditch Witch NW and bought our first 1.5 inch puller and it worked great for consistent reliable pulling of our dewatering wellpoints.

“Ever since then we have pulled out thousands of wellpoints consistently and quickly. We are very happy with this product and will continue using it as a core tool of the decommissioning portion of our business.”

Thank You,

Wire Mesh Grips and Catalog Strength

Wire mesh pulling grips, chinese fingers, pulling socks, stockings, support grips – whatever you call them, pulling grips are one of those tools that everybody uses for utility installations. Overhead, underground, through ducts and over sheaves, grips are a flexible, low-profile option.

Their greatest drawback is the limited strength and durability of the individual wire strands. Like any wire rope, abrasion and fatigue will eventually lead to a loss of strength and a broken grip. And, talking with one customer this week, “breaking strength” can depend on whose catalog you’re looking at.

Picture a typical bell curve. Starts small, gets big at the halfway point, gets small again. Most catalogs (DCD Design included) reference an Average or Approximate Breaking Strength. That’s halfway; by definition, half the grips are stronger than Average and half are weaker.

This weaker half is one reason we apply 3-5x safety factors to find the Safe Working Load. So a grip with an Approximate Breaking Strength of 12,000lb, should be limited to a Safe Working Load of 3,000-4,000lb when it’s new. As a grip becomes worn, the SWL should be further restricted.

grip_strength_range

Some catalogs refer to a Minimum Breaking Strength, down at the bottom end of the curve. Now 95-99% of the grips break above the quoted Minimum strength. This has one advantage: you can fine-tune your safety factors to include that certainty, though you’re starting from a lower Breaking Load. Really, you may find the SWL hasn’t changed much.

In the end, the quality of the grip will be the greatest apparent difference. DCD Design’s Pulling and Support grips are hand-made by experienced craftsmen, so you can be certain of quality and consistency. And, for a limited time, select grips are on sale!

Breakaway! – Another Duckt Production

The Duckt crew put together a great sales presentation for the DCD Breakaway Connectors, highlighting the quick assembly and range of breaking strengths available. The finished PowerPoint looked so good that we made a video clip as well, for general distribution.

Each connector, either the smaller -010 model or the larger -020, can fit five breakaway pins. By selecting the individual pin strengths, the rated breaking strength of the connector can be varied to meet the required load capacity.

The Operations Sheet lists off the Imperial load combinations; the Metric combinations are similar. Mix the two pin series, and you could dial in the breaking load wherever you want it!

“I want to fly like an Ea-” Oh, that’s copyright?

It’s been a busy month: DCD Design have created a new how-to video for the Eagle Cable Lasher, demonstrating some of the features and showing you how to load the lashing wire. (This ties in to next month’s promotion. Subscribe to the mailing list and keep an eye out for updates.)

We put this one together on the workbench and outside on our ‘test line’ to show off the lightweight Eagle. Like the larger Lineman lasher, it uses tension from the lashing wire to drive the drum, not traction on the strand. As long as you’re moving forward, you’re spinning!

In other news, we’ve just finished an intensive four-day basic training for Solidworks 3D software. It’s astonishing what this software can do: if you can sketch it on a napkin at lunch, we can create a 3D model by the end of the day! DCD Design have always been progressive when it comes to listening to our customer’s requirements; now we can assess and turn around a new design faster than ever before.

AND! Direct Horizontal Drilling of Edmonton have been setting up for a river crossing in the neighbourhood: a new gas pipeline is going to be pulled under the Fraser River tonight! Good luck and smooth pulling to them.
