Are you tired of constantly replacing worn-out A2B cables? Do you worry about potential fines and liabilities due to non-compliance with safety regulations? Many crane operators face these challenges, leading to costly downtime and increased risk.
Our A2B cable and A2B wire solutions are specifically engineered to address these pain points. Designed for superior durability, compliance with OSHA 1910.179 and ASME B30.5, and clear safety labeling, our cables provide a long-lasting and reliable solution for your crane's anti-two block system. Invest in safety, compliance, and long-term savings.
WARNING: Improper installation or use of this A2B cable may lead to catastrophic equipment failure, property damage, severe injury, or death. Ensure all installation and maintenance procedures adhere strictly to the crane manufacturer's guidelines and relevant ASME B30 standards. Electrical shock hazard. Disconnect power before servicing.
Our Anti-2 Block Wire Lengths are 110 feet, 139 feet, 145 feet, and 165 feet.

The "Silent" Two-Block: Remember, you don't have to touch the hoist lever to two-block. If you telescope the boom out without letting out the line, the block will pull straight into the tip. Always "payout" cable while extending.
Daily Check: Never start a shift without a "dry run" test of the A2B switch. Lift the weight manually (if safe) or slowly hoist up to ensure the lockout kicks in before the components touch.
Cold Weather Alert: In freezing temperatures, the limit switch can freeze "open" or "closed." Always verify it isn't iced over before your first lift.

Our A2B cables are built for longevity and designed to withstand harsh environmental conditions. While replacement frequency depends on usage and environmental factors, our customers typically experience significantly longer lifespans compared to standard cables.
Our A2B cables are engineered to meet and exceed OSHA 1910.179 and ASME B30.5 standards for crane safety. Each cable undergoes rigorous testing for electrical conductivity and insulation resistance in accordance with ASTM D470 standards, ensuring reliable performance and compliance.
Two-blocking occurs when the hook block, headache ball, or overhaul ball makes physical contact with the boom tip or the point sheaves. Essentially, you have run out of cable travel. When these two components collide, the hoist winch continues to pull, placing immense tension on the wire rope.
It is required because the force generated by a hydraulic winch can easily exceed the breaking strength of the hoist rope once the block is jammed against the tip. Without a safety buffer, the cable will snap, causing the load and the block to fall. This leads to catastrophic property damage, severe injury, or fatalities.
An anti-two-block (A2B) system acts as a fail-safe. It prevents the physical collision of components by:
Sensing Proximity: A limit switch or weighted "dead man" switch detects when the block is getting too close to the boom tip.
Function Limiting: It automatically locks out the specific crane functions that would worsen the situation: hoisting up, telescoping out (extending the boom), and booming down (which increases the distance between the tip and the winch).
Yes. Under OSHA 1926.1416, anti-two-block devices are classified as "Category I" operational aids. For most modern construction cranes, OSHA requires these systems to be functional. If the system is non-functional, the crane must generally be taken out of service unless specific, temporary alternative measures—such as a dedicated spotter—are used under strict legal guidelines.
Great turn around on a custom sticker and a great product as well!
In todays online deceptive marketplace it is a pleasure to work with a company that sticks to old school principles. This company makes a fantastic product and backs it up with impeccable service. Not only do they deliver a quality product they honor their word, not something you find in most businesses today.
The stickers purchased for the crane direction identification was a great addition for the operators to use the cranes safely. Inspectors I deal with like everything labeled for ease of operation and the safety aspect it offers for the person controlling the cranes and the co-workers that may be around during the operation.
I can't say enough!!! Order was accurate, great quality and service was second to none. Definitely Use for ALL FUTURE ORDERS!!!!!
Great customer service from design to receiving. Thanks
Wow, received great service. Designed the sticker and received in days. Thanks to all your staff.
First off I would like to point out that the customer service is amazing. Secondly, the stickers are the perfect size to not take too much room on a hard hat or a type 2 helmet. We recently made the move to type 2 helmets and my foreman and superintendents were not to ecstatic about it but when they knew they would get new stickers they were happy and specifically asked for some that said they were trained in this. Bought some others from another store but those were round and took up way too much room! Found these and knew that they would be the perfect size. They look great and everyone is happy with them.
These stickers are made out of the great durable material. These fit our type two helmet that the company just moved over to. A lot of our foreman and Superintendent were not happy with the move to the helmets and when we did, they asked specifically for a first aid CPR sticker. I ordered some from another website and those were just too big. They took up too much room, but these were perfect. when I handed them out my guys were ecstatic and happy that these were just the right size for the hardhats that they are utilizing now in the field. The customer service was also a great help in finding these hardhat stickers.
These are great decals. Exactly what I was looking for. High quality and look good too.
Perfect for company cars !!
There are many safety sticker companies today on line, but how many will provide excellent customer service like Crane Safety Stickers? My order had a problem on arrival and after contacting Dave at CSS he promptly responded with an email and immediately packed and shipped a new product the next day. I paid nothing. No charge for a brand new product and no charge for shipping. Hard to beat! I highly recommend Crane Safety Stickers.
These stickers are exactly what we were looking for. The big letters make them easy to read for our energy control program and they don't feel thin and weak. Definitely will be ordering more.
