GREER COMPANYCrane SystemsCable Storage ReelThe cable storage reel is a hand-cranked extension reel that can accommodate enough cable formaximum boom length. Excess load cell or anti two-block cable for shorter boom lengths can bestored on this reel.1. Clamp the cable storage reel to the lattice on the inside of the base section of the boom. Thehole pattern on the base of the reel will accommodate varying clamp sizes.2. Tighten the wing-nut on the front of the extension reel. The wing-nut controls the rate ofrotation of the reel.Boom Angle Sensor A220220Refer to Figures 3 and 4, page 10.The mounting position for the boom angle sensor must be either on the outside of theleft side (operator's left when seated in the cab) of the boom, or on the inside of theright side of the boom, as shown in the illustration.1. With the boom in a horizontal position, mount the boom angle sensor vertically (connectortoward pivot) with the top of the sensor parallel to the centerline of the boom. Mount thesensor using 1/4" bolts, studs, or weld plate.2. Connect angle sensor cable to angle sensor. Route the cable along the lower edge of theboom. Make a loop in front of or behind the boom pivot, ensuring that the cable does notstretch, pinch, or abrade when the boom is at a high or low angle.3. Continue routing the cable into the cab to connect to the angle connection from the displayconsole.4. Install cable clamps/cable ties every two to three feet along the boom.GREER Service Department:Tel: (714) 259-9702 Fax: (714) 259-7626LALT 1151L Installation/Calibration Manual for Lattice CranesPN W310112A 12/05/ 029 of 39

GREER COMPANYCrane SystemsSwing-Arm Mounted TensiometerSingle or Dual Load ChannelRefer to Figures 5 and 6 on pages 12 and 13.1. Mount the swing-arm tensiometer at the top of the tip section or at the top of the base sectionof the boom.This position is determined by the number of tensiometers to be installed and whether or notthe winches are side-by-side or tandem. The method of installation is the same for either tip orbase mount.2. With the boom lowered to the ground:a) Lay the swing-arm bracket on the top of the boom.b) Position the bracket and loosely install the clamps without interfering with the lattice.c) Mount the swing-arm to the bracket with the bolt and nut supplied.3. Place the landing pad bracket onto the top of the boom so that the center of the bracket isapproximately 7 inches from the end of the swing-arm.a) Loosely install the clamps.b) Place the tensiometer on top of the landing pad with the load cell cable towardthe swing-arm.c) Bolt the tensiometer to the swing-arm with the bolt and nut supplied.4. Before tightening the clamps on the swing-arm bracket and landing pad, ensure that the centerof the tensiometer is over the center of the landing pad.If two tensiometers are to be installed, mount the second tensiometer before tightening theclamps. Check for freedom of movement of the joints on both ends of the swing-arm.5. Remove the bolt that secures the rocker-arm/center roller assembly during shipping. Feed thehoist cable under the back of the end roller, over the top of the center roller, and under thefront roller to the head sheaves.Continued on next pageGREER Service Department:Tel: (714) 259-9702 Fax: (714) 259-7626LALT 1151L Installation/Calibration Manual for Lattice CranesPN W310112A 12/05/ 0211 of 39

GREER COMPANYCrane SystemsAnti Two-Block Switch – MainThe mounting method used for installing the anti two-block switch main is dependent on theidentification number on the switch arm. Follow the instructions for the appropriate type below andRefer to Figure 7 on the next page for left-hand mounts. For right-hand mounts, refer to Figure 8 onpage 16.1. Remove the two 1/4 – 20" truss head screws from the main anti two-block switch cover and setthe cover aside.2. Look at the pivoting switch-arm.• If the arm is cast with the number 065181, follow Type 1 (the arm will also have a G.L.G.cast into it).• If the arm is cast with the number 065218, follow Type 2.TYPE 11. Lower the boom to 0 ° (zero).2. Find and mark a location on the boom head where the anti two-block switch can bemounted at about a 30 ° angle to the boom.Measure the angle from the bottom front edge of the switch.Ensure that the switch will not interfere with any of the attachments when fitted.3. Remove the back weld plate from the switch.4. Weld the plate to the boom.5. After allowing the plate to cool, clean and paint the plate.6. Mount the switch to the plate and replace the cover.7. Attach the chain and weight assembly to the switch swing-arm.TYPE 21. Lower the boom to 0 ° (zero).2. Find and mark a location on the boom head where the anti two-block switch can bemounted parallel to the boom. The switch must not interfere with any of the attachmentswhen fitted.3. Remove the back weld plate from the anti two-block switch.4. Weld the plate to the boom.5. After allowing the plate to cool, clean and paint the plate.6.

GREER COMPANYCrane SystemsAnti Two-Block Switch – JibThe mounting method used depends on the model number of the jib anti two-block switch.1. Remove the two 1/4-20 truss head screws from the Anti Two-Block switch cover; set coveraside.2. If the pivoting switch arm is cast with the number P065181,use type 1 (page 14).If the arm is cast with the number PO65218, use type 2 (page 14).The arm will also have a G.L.G. cast into it (exception: not on P065218).3. In some cases, the anti two-block switch will have to be mounted behind the jib sheave. The jibswitch is connected to the main anti two-block switch with a cable.A small loop, which can be coiled up when not in use, will be required to connect the cable tothe main switch.a) Connect the jib cable to the jib switch.b) Lace the cable inside the jib where it cannot be pinched or damaged.c) Secure the cable every 3 to 4 feet.Anti Two-Block Switch - rooster/auxiliaryThe rooster/auxiliary switch is installed the same way as the jib switch but in most cases the cablefrom the switch will be long enough to connect straight to the main anti two-block switch. Clampthe cable to the boom head to prevent damage.GREER Service Department:Tel: (714) 259-9702 Fax: (714) 259-7626LALT 1151L Installation/Calibration Manual for Lattice CranesPN W310112A 12/05/ 0217 of 39

GREER COMPANYCrane SystemsIntroduction to the Calibration ProcessAfter installation, the LALT 1151L System for lattice cranes must be calibrated before it canoperate.Take a moment to become familiar with the keys on the face of the display below. These keysalong with the required tools listed below and the two screens on the face of the display are all thatis necessary to calibrate the LALT 1151L System.Required Tools• Tape measure• Inclinometer (for measuring the angle of the boom)• A test weight for each hoist that is heavy enough to make a single part line pull at least equalto 50% of the hoist rope maximum capacity. (See example for calculating the correct testweight on page 31.)Figure 1Contrast Control KnobGREER Service Department:Tel: (714) 259-9702 Fax: (714) 259-7626LALT 1151L Installation/Calibration Manual for Lattice CranesPN W310112A 12/05/ 0223 of 39

GREER COMPANYCrane SystemsIdentifying Calibration Needs• If the LALT -1151L System has never been calibrated:complete Sections A−J for single winch cranes and Sections A−L for dual winch cranes.Always calibrate the System in the order shown in the following pages. Always set theboom length before entering the calibration mode.• If the LALT -1151L System has already been calibrated, but needs recalibration in aparticular area:1. Check the boom length and parts-of-line (Sections B & C) for accuracy.2. Enter the Calibration Mode (Section D).3. Recalibrate only those areas requiring change.4. Do not perform initialization steps in Section A; to do so will cause all previouslystored calibration data to be lost.If the displays are blank or all black, adjust the contrast knob (Figure 1, page 23) on thebottom of the display unit.A InitializationPerform the following "INITIALIZATION" steps 1-7 ONLY when calibrating the ENTIRELALT -1151L System.

GREER COMPANYCrane SystemsM Aux. Span Calibration"AUX. SPAN" is the internal adjustment that causes the System to correctly indicatethe weight of the auxiliary winch load.1. Prepare to lift the aux. winch test weight at a safe radius (see capacity chart) forthat load. Use a test weight that is heavy enough to make a single part line pullat least equal to 50% of the hoist rope maximum capacity.Example for calculating test weight: A hoist rope with a 10,000 lb. capacity,reeved to 1 part of line, at 50% of the hoist rope maximum capacity will have aminimum test weight of 5,000 lbs. (10,000 x 1 ÷ 2 = 5,000).2. Press the r arrow until the display reads: "Cal. Aux. Span."3. Press ENTER to start the routine.4. Pressing the r and o arrows, set the TEST WEIGHT.5.
