NEW ClimbTech BANTAM Beam Slider

May 19th 2017

We're pleased to announce that the NEW Climbtech BANTAM Beam Slider is now available.  The BANTAM is a removable and reusable sliding I-Beam Anchor, which is easy to place, adjust and move.  The anchor is designed to easily slide along the beam, trailing the worker. This new, improved Slider features an increased adjustable width and an improved adjustment mechanism, which is simple to use, even when wearing gloves!  The Paw inserts are made from a self-lubricating Silicone Bronze Alloy, which is designed not to bind on the beam.  The BANTAM can be used over-head and at foot level (please reference User Manual) and is fitted with a swivel eye, which rotates through 360 degrees.

Product Upgrade- ZIPPEY

May 16th 2017

ISC products are constantly evolving and since the first launch of Zippey more than 3 years ago, we have gathered feedback from zip operators from all around the world and fed them into an engineering review. This review has specifically been driven by a number of concerns about the variation in performance/longevity of the Zippey trolleys returned by various customers/test sites around the world. We know that different sites around the world have very different environments (humidity, coastal locations, sandy environments...etc.) and these have significant effects on the bearings.


Review Findings

1. Cable:  Cable Construction is a key factor.  Coarse cable can be of significant detriment to the longevity of the trolley and especially the bearings.  There is a reasonable correlation between the coarseness of the cable ('6 x 25' cables being the worst cable type), and the life of the bearing.

We like to use the analogy of having a Ferrari and driving it on a cobbled street! You just wouldn’t!  A Ferrari should be driven on smooth highways...and Zippeys (and all Zip Trolleys) like to run on smooth cables!


2.  Bearings:  Our investigation into the quality and type of bearings that we use found that they needed to be sourced directly from a reliable, specialist manufacturer to ensure consistent quality.  After all, the bearings are the critical component in the trolley!

We consulted with a bearing specialist from Schaeffler (a German bearing manufacturer) and their recommendations enabled us to select the most suitable bearing for the Zippey. The bearing also has a specific seal type (recommended by the Applications Engineer), to reduce the effect of corrosion.  The use of this specific seal means that the Bearing doesn't need to be maintained or re-greased.

The bearing has an RPM (also known as 'Limiting Speed') of 20,000rpm, which will allow an optimum max theoretical speed of 70mph/113kph (based on a wheel diameter of 30mm (1 3/16").

3. Wheels: The advice from the bearing specialist also confirmed that the bearing housing (the wheel), should be of a sufficient hardness to support the bearing. We have therefore increased the hardness of our wheels, so that they are hard enough to resist any deformation during use and to provide adequate support for the bearing. We have switched to a special type of Stainless Steel which provides an outstanding combination of high strength and optimal mechanical properties, suited to the typical range of operating temperatures. This material also provides excellent corrosion resistance. Although in very harsh environments, it may gradually develop overall light rusting and pitting, this superior material is vastly superior to the standard Heat-treatable Stainless Steels. 

As part of the design review, consultation with wire cable specialists and LEEA, lead to a consensus of opinion that the harder wheel material would not result in a detrimental effect on the wire cable-  in fact, the hardness of the new wheels is still comparable with competitor trolleys.

The new wheel material is designed to be factory-hardened, as the material must be hardened after the machining process.  This hardening process results in an iridescent (purple/bronze) coloured finish to the surface of the wheel.  This is a normal effect of this superior material and treatment.

The integral design of the Zippey remains unchanged and we're still using a double row of bearings for stability during flight, (single bearings can cause the trolley to try to climb the cable which results in uneven wear to one side or the other).


Other upgrades to the Zippey Range include:

NEW Bumper Material
Flat end bumpers are now made from an impact resistant Polymer which has significantly increased the wear resistance when impacting an end stop/braking system.

Improved Gate-closure Spring
The new design of the Stainless Steel gate-closure spring offers improved durability/life span, whilst offering the same, positive functionality allowing the Zippey to be easily mounted/dismounted.

Re-greaseable Version  DISCONTINUED
The version with the greaseable bearings have been made obsolete by the above improved bearings & seals and will therefore be discontinued.

NEW Bumper-mounted Grab Bracket
We will be launching a version with bumper-mounted grab bracket, for use with Trolley-retaining braking systems...coming soon!

Rope Wrench- CE APPROVED Kits!

April 20th 2017

Following the well-publicised intervention by the German Trading Standards authorities we were asked by our German dealer Freeworker to urgently address the issue of the Rope Wrench not being CE marked. Over the last few weeks we have been liaising between the German Authorities and the UK Notified body for CE testing and we can now announce that the Rope Wrench kits can and will now carry a CE mark. This CE marking is done under the PPE Directive 89/686/EEC and EN12278 Pulley Standard and, for unavoidable reasons of test methodology, it applies to a combination of Tether and Wrench. This means we have created three versions as follows:

1. Rope Wrench & Single Leg Tether- CE Approved as a kit

2. Rope Wrench & NEW Twin Leg Tether- CE Approved as a kit

3. Rope Wrench only- which cannot and will not feature a CE mark/approval and so can only be sold into countries where CE marking is not mandatory (e.g. USA) and also where the customers in those countries are not therefore forced to buy the approved tether.

NOTE: the testing was carried out with an MBS of 24kN which additionally means that the combination of Tether and Rope Wrench exceeds the ANSI minimum strength test criteria of 5000lbs. Dealers and users should be aware that other tethers may not meet this strength requirement. 

For further background information, please see the 'Rope Wrench CE Approval Statement' below.

ISC 2017 Asian Distributor Conference

April 11th 2017

We're very excited to welcome our Asian Distributors to Chiang Mai (Thailand), for three days of meetings and practical demonstrations and workshops, at some great venues! The event will take place from the 19-21 April, beginning with a conference/meeting.  

Practical sessions will include an afternoon session at Phoenix Adventure Adventure Park, showing the SmartSnap Continuous Attachment Device, Zippey Clip'n'Zip Trolley, the ZipSpeed Trolleys, together with the Parachute and Superman Style Harnesses.

The practical session for Rope Access/Rescue will take place at an awesome abandoned multistorey building.  This will be a fantastic site for putting a wide range of gear through its paces, in a range of rescue scenarios!  We will be joined by guest demonstrator Mike Walrond (Rescue Specialist, Ferno Australia), designer of the mighty Arachnipod Total Edge Management System.  Mike will be on hand to lead the group through a range of Arachnipod scenarios, showing the numerous configurations and capabilities of the system!

Day three will be spent at the beautiful Queen Sirikit Botanical Gardens (QSBG), or fomerly known as Mae Sa Botanic Garden.  This is the first botanical garden in the country to meet international standards for scientific controls, collections and education.  The main objectives of the garden are  to serve as a centre of Thai flora for botanical study and research, to render services concerning biodiversity and environmental conservation, as well as to provide an aesthetic place for the general public.  The wonderful trees and scenery make this the perfect venue for our Arborist/Tree Climbing and Rigging Demonstrations, hosted by ISC' s Rich Hattier (North American Sales Manager, Former Production Climber and Champion Tree Climber) and Adam Davies (ISC Product Specialist and Certified Arborist).

We will also be joined throughout by another guest demonstrator, Sammy Chun. Sammy's long list of credentials includes, SPRAT, IRATA, ACCT  & ISA certifications.  Sammy is Training Director of Hong Kong Rope Union and Chairman of Hong Kong Tree Climbing Championships.  Sammy has also put together a team (including ISC's Adam Davies!), who will compete in the Grimp Day this year!  We're absolutely delighted to have Sammy on board to bring his vast experience to each day of the demonstrations!

February 7th 2017

The ISC STRYDER Foot Ascender has been designed following extensive feedback from industry users.  During the development of STRYDER, durability and functionality were at the top of the priority list. STRYDER utilises tried & tested geometry, to provide a smooth upward movement and positive engagement on the rope. 

STRYDER is fully adjustable on both the horizontal and vertical straps, allowing the user to position the device on the boot, according to preference.  The straps and protective under-foot sleeve are made from a specifically developed webbing, which has passed extensive abrasion testing.

The combination of the creep-free webbing and the mounting slot design, means that the device should remain firmly in position throughout use.  The main strap is tightened by pulling firmly on the strap and is released by pulling upwards on the toggle, in a one-handed action.

STRYDER utilises the same unique Stainless Steel cam used in our Hand Ascender.  The coned cam-face allows positive engagement on the rope for a firm and reliable grip, with minimal wear to the sheath.  

Great engineering attention was placed on the spring, which has been meticulously trialled to ensure that it offered sufficient tension (so as not to easily ‘pop-off’), but still allow the device to move freely upwards without towing the trailing rope.

The foot-lever can be used to open/close the cam, with the other foot.  The foot-lever can also be hooked over the body of the device, to hold the cam in the open (disengaged) position.  Should the user prefer, the foot-lever bar can be removed, by unscrewing an Allen screw.  Removing the foot-bar allows greater pivot range of the cam.  This in turn allows the user to deliberately remove the rope from the device, by using a kick technique with only the leg that the device is mounted on.
