Compression-type stringing clamp (for use with ACSR conductors)
This device is used for the temporary connection of the tips of various electrical conductors during stringing. In addition, it is also used to put temporarily connected multiple conductors through a tensioner.
It has reliable retention force by being compressed. Along with this, the high stringing block passage performance makes the product well-suited for improving safety and reducing labor of stringing work.
|ACSR, HDCC, OPCW, GSW and AC conductors,|
and other similar conductors
|Tolerable stringing tension: 20% of UTS|
Minimum tensile load: 60% of UTS
* UTS: Ultimate tensile strength of a conductor under the minimum tensile load
SR ring mounter
This machine automatically mounts snow accretion restrainer rings (SR rings), which are intended to prevent damage caused by snow to overhead transmission lines.
This machine has reduced size and weight to ease high-place work and alleviate any increase in conductor sag. In addition, its simple structure allows the machine to be easily used and operated. This machine can be operated via wireless remote from a tower or the ground.
|Available conductors||38 to 100 mmm2|
|Clearance between rings to be mounted||Settable at any value|
|Power||24 V DC battery|
|Distance that can be travelled||1,200 m (each time the machine is fully charged)|
|Number of rings that can be mounted||4,000 (each time the machine is fully charged)|
|Operation||Wireless||Wireless output: specified low electric power (*1)|
|Reach from above the ground: approx. 80 m|
|Mass||Approx. 25 kg|
*1: Requires no qualifications or the filing of applications as prescribed in the Radio Act. As of 2011, the newest model of this product is under development. Please contact us for more details.
Cable checking machine capable of passing through a damper (Model NII) (of high vision specifications)
This device records images of the electrical conductor to a memory stick inserted into to a high vision camera in order to check the appearance (maximum recording time: 175 minutes (when recorded in PRO Duo 8GB of the AVC HD 5M (LP) type)).
This device uses a mirror to capture the images on a total of three planes of an electrical conductor (two upper planes and one lower plane) at one time.
On the left side of the image, a counter indicator is displayed to show the number of roller revolutions. The count is incremented by “1” when the roller has made five revolutions.
The device goes forward and backward and stops through wireless operation.
It can pass through a bolt-free damper or a damper with a breakaway bolt made by Viscas Corporation that is intended for use with ACSR stranded conductors of 330 mm2.
|Acceptable conductor size||(Outer diameter): 9.6 mm (St stranded conductors of 55 mm2) to|
25.3 mm (ACSR stranded conductors of up to 330 mm2)
|Outline dimensions||W 1017mm x D 348mm x H 738mm|
|Power specifications||DC 12 V, 22.5 W DC motor with speed reducer|
We also offer a cable checker withdrawal device that can be wirelessly operated to withdraw a cable checking machine when the machine stops during a check for any reason.
Braking machine (Model SGB-2468)
This braking machine is used during wiring work to prevent rope sag when withdrawing the final rope used with a suspended stringing block.
|Braking force||8 to 24 kg|
|Outline dimensions||W 386mm x D 162mm x H 280mm|
|Acceptable conductor size||St55mm2 to ACSR810mm2|
Suspended stringing block (Model KSA100)
This device is a ring-type suspended stringing block that is ideal for pulling off a pilot rope and electrical conductors during low-tension stringing. It consists of six rollers that are configured in a manner such that they form circular contours. This ensures contact of electrical conductors with the rollers at all times.
|Outline dimensions||W 189mm x D 65mm x H 210mm|
|Acceptable conductor size||St55mm2 to ACSR410mm2|
|Stringing capacity||Vertical load: 150 kg |
Stringing speed: 30 m/min.
|Pilot rope||φ 14 Kevlar rope|
One-touch hooks (used mainly with principle and web members)
This hoisting accessory is used for the assembly of steel tower members. It can be removed by means of remote manipulation of the rope after the temporary tacking of bolts.
It has a mechanism that allows its removal only when it is under no loads. This ensures the safety of work.
As its removal does not involve worker’s climbing the tower, the crane’s standby time can be reduced.
|Model||For principal members||For web members|
|Model P30-F||Model P20-F||Model T20|
|Acceptable flange thickness||160 mm or under||74 mm or under||–|
|Acceptable steel pipe diameter||–||–||φ 400 mm or under|
|Outline dimensions||396mm x 168mm x 80mm||330mm x 140mm x 80mm||φ175mm x 100mm|
