Guru’s Pro-Tips for the Crew

  • 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.

Yes, our A2B cables are designed to be compatible with a wide range of crane models and cable reel types, including Hirschmann LWG, LG, and PAT. Please consult the product specifications for detailed compatibility information.

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.
