2.4 LSI GS075 Anti Two Block Installation Instructions
Verify the anti-two-block switch is programmed to the GS550 display. Switches shipped with displays are pre-programmed in the factory. Test: if the switch has been programmed to the display then the display will go into two-block alarm when the switch is released. Press Bypass to silence the alarm until the next two-block event or simulation. If the switch has not been programmed to the display, this should be done before proceeding with installation. See the section How to Add a Sensor to the GS550.
2.4a 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.
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.
For live end mounting on multiple sheave blocks with sheaves greater than 16 inches (41 centimetres) in diameter consult your service representative.
For fast line weight installation place the anti-two-block switch mounting bracket directly below the sheave center as low and as close to the edge of the sheave as possible. 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.
2.4b GS050 Installation
1. Mount the GS050 on the bracket and verify that the GS050 can rotate freely through all possible boom movements without being able to come off the bracket.
2 . Install the weight and chain assembly around the cable and attach the other end of the chain to the GS050. Tighten all the chain links of the chain assembly.
3. Adjust chain length as required, see sub-section Chain length adjustment.
4. Test system function.
2.4c LSI GS075 Anti Two Block Installation
1. For the LSI GS075 anti two block installation on the LB011 (switch bracket) make sure the switch bracket is already installed on the crane boom (step 2.4a), with the antenna of the switch pointing away from the boom.
2. Install a weight and chain assembly to the eye nut. The weight and chain assembly can either be supplied by LSII (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.
2.4d Chain length adjustment
1. Chain length adjustment № 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 suspend and clear the sensor chain and weight.
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.
2. Chain length adjustment № 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 that determined at the minimum boom angle.
3. Chain length adjustment № 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.
