SORAT technique
Safe and flexible rope access
for investigation and inspection.
26 years safe-proven history.
We are rope access engineers in Japan and SORAT method allows engineers to move freely yet safely in the air.
SORAT rope access technique is specialized for engineers who work on investigating or inspecting cliff, dum, bridge or any other constructions. It is up-to-date and renovating. With SORAT technique,you can move vertically,horizontically and safely in the air with one main rope.
Also you can finish rope access work quickly and safety on schedule. To reduce the risk of cuts,we always use rope guard ,re-blay and deviate a rope.
Mutiple anchor test and pre-load test deliver maximum safety to professional rope access work.
Safety is a first priority for SORAT.
Keystone JAPAN has started rope access buisiness in Japan for 26 years. No serious accidents has never occuured because of our highly-skilled SORAT team. We stick to our strict safety rules. Our clients are always surprised with our safety rules and achievements.
Let me explain SORAT briefly.
For engineers who involved inspection and investigation
・SORAT method was developed and improved as we conducted long-term and thorough building investigation,inspections and maintenance.
・SORAT method is used by building inspection engineers, not by construction workers.
26 years no accidents
・Our SORAT engineers has qualified for professional rope access works.No fall accidents have never occurred for 26 years.
One anchor line with safe and flexibility
・We use mainly only one main rope and it doesn’t require any backup ropes.
・We prepare for multiple anchor points for weight distribution and back-up.
・To reduce the risk of cuts, we always use rope protectors and try to re-bley or deviate an anchor line to prevent damage and distribute the weight.
SORAT engineer use rope protectors when we need to protect a main rope from abrasive surfaces and sharp edges in various work places.
Why safe enough with only one main rope ?
We understand you think it is dangerous to work at height with one main rope.
Let us explain the reason why we can secure maximum safety with only one main rope.
1.Test rope and gears
An anchor line is tested securely by experienced SORAT engineer with SORAT Level 3 certification before we start to work. Also we inspect and maintain all gears.
2.Test anchor points
Anchor points have to support engineer, weight of the rope, and anything attached to the rope. we check it by pre-load test.
3.Test gears while harness is suspended with a anchor line
Before we start to work,first we have to confirm that all gears works fine and anchor points can support engineer, weight of the rope, and anything attached to the rope.
SORAT engineer is connected securely to a tensioned anchor line.
This means fall accident can hardly happen if an anchor line is cut or knots are not correctly tied.
Any serious accident can hardly happen in case you skip some very basic steps.
It seems for you that work at height with one main rope is dangerous.
But the truth is that we did not face any serious accidents for 26 years.
Safe rope access with maximum flexibility.
One of the best benefit of SORAT method is that we can work at height with one mail rope as safely as with one main rope and one back-up rope.
With one main rope,we can traverse a rope to reach challenging locations more easier and safer than traversing 2 ropes(a main rope and backup rope).
In other words,without having a backup rope,we can access any location which is too difficult and complicated to reach with 2 ropes.
We created SORAT method in the 1990s. Our SORAT method and security policy have received solid reputation from many building consultation companies and Japan’s Ministry of Health, Labor and Welfare.
SORAT is recognized as a safe rope access technique under Japan’s strict safety policy.
