SECTION 1. MECHANICAL DESCRIPTION OF THE SYSTEM 1.0

MECHANICAL DESCRIPTION OF THE COMPONENTS

1.1

Pressure Transducer: The pressure transducer transforms hydraulic pressure into an electric analogue voltage signal. Two pressure transducers are connected, one to the rod side and one to the piston side of the lift cylinder. The pressure transducer is connected to the central unit with a four conductor, double - shielded cable.

The power supply voltage is ± 5V. The output signal is 0.00V under 0 pressure to -1.00V at max. pressure (4410psi) 1.2

The Length-Angle Transducer: The length-angle sensor (LWG) is a combination of two transducers in one box, fitted at the base section of the boom. It measures the length and the angle of the boom.

 A reeling drum drives a potentiometer, which is the length transducer. Part of the length transducer circuit is the length cable on the drum, which is a two-conductor cable (screen and live). It is connected to the anti-two-block switch at the boom head and to a slip ring body in the LWG. The angle transducer is fitted in a small box filled with oil. A pendulum drives the axle of the angle potentiometer. The power supply voltage for both is -5.00V The output signal for the length transducer is: -0.500V up to -4.500V The output signal for the angle transducer is: -1.875V up to -3.125V 1.3

Anti-Two-Block Switch: The anti-two-block switch monitors the load block and it’s relationship with the head of the boom. In working condition the switch is closed. When the hook block strikes the weight the circuit opens, disengaging a relay output to the lock out solenoid valves, where applicable. To check the cable for damage, (short circuit to ground) there is a 4.7k resistor between ground and the contact of the switch, to give a signal back to the central unit. The weight at the anti-two-block switch keeps the switch closed until the hook block strikes it.

1.4

Console: The console displays all geometrical information such as length and angle of main boom, working radius and head height of the boom. It also displays the actual load and the maximum load permitted by load chart. Furthermore, it has an alarm horn, a warning light for overload, and a pre-warning light. The analog instrument shows a percentage of the total permissible moment. The console has a switch for the operating modes (duty-selection switch for crane configurations) and a switch for the reeving of the hook block. It also has a warning light for anti-two-block conditions and an override switch for overload or anti-block condition. The console also has a toggle switch that engages digital inputs to identify various hoist options.

Duty Selection Switches (Digital Inputs): The system has to be programmed for the lifting area configuration. The crane is going to be worked in e.g. main boom on outriggers over front, or rear, or over the side for 360 degrees. For this information from the crane, we use micro switches that are installed in the electrical swivel and tells the system the location of the boom. We also use micro switches on the counterweight that informs the system if the counterweight is installed or not where applicable.

3. BROKEN LENGTH CABLE

PROBLEM: Damaged or broken length cable.

Replace length cable using the following procedure: 1 2 3 4 5 6 7 8 9 10 11 12 13 14

Cut old cable at cable drum Disconnect damaged length cable from junction box at the boom nose. Open cable reel cover and disconnect wiring from connection block. Pull 7 conductor cable out of strain relief. Remove cable reel from mounting brackets. Remove damaged length cable, which is mounted to the slip rings in the cable reel, from slipring connection. Refer to Drawing 1 in Section 11 - Drawings On the back side of the cable reel, open the strain relief attached to the axle in the center of the drum. Pull existing length cable out of the cable reel. Pull new length cable through the hole, pipe and strain relief and push it through the axle of the reeling drum. Tighten strain relief to ensure sealing. Reconnect the length cable to the slipring. Refer to Drawing 1 in Section 11 - Drawings. Remount cable reel to the boom. Turn reeling drum clockwise to spool the new cable neatly onto the drum. Set preload on cable reel by turning the drum counter-clockwise 5 to 8 turns.
