GM085_ENG_rev.docx www.loadsystems.com 3 1. Overview The anti-two-block switch comprises of the radio transmitter, battery and switch mechanism. The switch mounts at the boom tip. A weight and chain assembly is attached to the bottom piston rod of the A2B switch. When the weight assembly is lifted by the ball/block, the internal switch in the A2B will trip an alarm, warning the operator of a two-block event. The switch mounting bracket design allows the switch to rotate in two axes. The quick slip design of the mounting bracket allows the switch to easily be added or removed from the switch mounting bracket without the need for tools. 2. Switch Bracket Installation LB011 Position the sensor mounting bracket. To ensure that the sensor can pivot securely on the mounting bracket throughout the full range of boom angle, the mounting bracket must be positioned at a 30° from horizontal with the boom parallel to the ground and such that the locking pin of the mounting bracket points up. Bolt or weld securely. Figure 1: Bracket footprint and orientation, all dimensions in inches, not to scale Figure 2: Anti-two-block switch placement on a telescopic boom If the head sheave diameter is between 8 and 16 inches (20-41 centimetres) then two mounting brackets will be required to permit both live and dead end mounting. Figure 3: Anti-two-block switch placement for live end mounting on a latice boom Figure 4: Anti-two-block switch placement for dead end mounting on a lattice boom For live end mounting on multiple sheave blocks with sheaves greater than 16 inches (41 centimetres) in diameter consult your service representative. WARNING! Keep the anti-two-block switch away from the boom and any connecting metal structures when welding mounting brackets to the boom. Proximity to welding may cause permanent damage to the anti-two-block switch and render the anti-two-block system unsafe.

Place the fast line weight mounting bracket on the opposite side of the sheave with the chain hole pointing down and lined up opposite the pivot of the anti-two-block switch mounting bracket. Figure 6: Fast line weight installation 3. GS085 Installation Install the GS085 on the LB011 (switch bracket) already installed on the crane boom(step 2), with the battery cover pointing away from the boom. Install a weight and chain assembly to the eye nut. The weight and chain assembly can either be supplied by LSI (as an option) or the original assembly supplied with the crane. If the original assembly is to be used, its total weight must not be more than 13lb and the chain weight must not exceed 2lb. 4. Chain length adjustment Chain length adjustment No.1 – minimum boom angle a. At minimum boom angle, with no additional weight on the hook block and one part of line only, lift the boom just enough to have the hook block off the ground and clear the sensor chain and weight. Figure 7: Chain length adjustment - Minimum boom angle b. Hoist slowly until the buzzer sounds. Note the hoisting distance remaining; this distance must be great enough to allow the operator and the lockout system, if installed, to prevent a two-block event. If necessary, add chain between the sensor and weight to increase warning distance. If still insufficient, contact your service representative. Chain length adjustment No.2 – maximum boom angle a. Raise the boom to the maximum angle. b. Hoist slowly as described in Step 1.b. Verify that the warning distance is equal to or greater than
GM085_ENG_rev.docx www.loadsystems.com 5 that determined at the minimum boom angle. Figure 8: Chain length adjustment - Maximum boom angle Chain length adjustment No.3 – speed test: Lower the boom until the weight height becomes visually clear to the operator. Repeatedly create two-block, progressively hoisting faster, to ensure that the warning and lockout work within acceptable amount of time and distance. Increase the length of the chain if needed. Figure 9: Chain length adjustment 5. Operation The radio anti-two-block is fully functional. It does not need to be calibrated or adjusted. Refer to the GS375/GS550/GS820 manual for how to add this sensor to the sensor list to be displayed. 6. Security The radio anti-two-block is equipped with a failsafe power system allowing it to instantaneously communicate an alarm via radio signals if the battery of the power circuit is rendered inoperative. In the advent of a radio failure, the radio communication protocol will generate an alarm within 5 minutes of the loss of signal. 7. Battery replacement After a period of about 4 years, the battery may need to be replaced. To ensure the same performance as the supplied battery, replace with: 3.6V lithium D cell If this type of battery is not available, this type can be used but with a reduced life: 1.5V Alkaline D cell To replace a battery, unscrew the 4 cover bolts of the battery cover and remove it. Change the battery, verify that the o-ring is clean & in good shape and re-install the battery cover. IMPORTANT! To increase chain length, only use lightweight chain
