GENERAL INFORMATION AND OPERATING INSTRUCTIONS

1-1. PURPOSE Al'.J"'D DESCRIPTION.

The Crane Remote Control System provides a means of operating an overhead, un­manned, two hoist crane. All of the various crane funccions can be remotely controlled by an operator standing at or below ground level. The system is comprised of four units: a trans­mitter-controller, and a crane receiver and two interposer relay cabinets which are mounted in the crane.

a. . Transmitter-Controller. - The transmitter-controller is a battery operated unit, worn around the operator's waist, and by a heavy-duty leather belt. Modular con-struction and the use of solid state components provide for a small, compact, light-weight unit. Eleven tone oscillators, which are wired and bolted to a printed circuit board; a modu-

other , comprise the transmitter-con,.,. troller. The tone oscillator circuit board, and the modulator-transmitter are both attached to the transmitte~-controller frame.

Four ro.:.,,,;:ing switches, are located on the front panel of the unit, control the motions of the crane. Each rocking switch is comprised of two separate switches. The top half of the rocking switch operates one switch, and the bottom half operates the other switch. A stop switch is associated with each rocking switch and)s located below the respective rock­ing switch. There are two momentary switches located on the top of the unit; 1 one for opera­tion of the crane bell and a bar operated dead.man switch power to the transmitter­controller. In addition, located on the front of the unit are a lockout toggle switch, and a crane power control switch. Control of power to crane is a special feature available, which en-ables the operator to turn crane power on off without having to climb up into the crane and eliminates the need for cumbersome cables.

~ocated '. ,3ide of the transmitter-controller are three mercury vertical interlocks, that will open if unit is held too far from upright position. This is a safety feature that removes ~)ower to the unit if the transmitter-controller is dropped, or if the operator falls. A diode, also located inside of the transmitter-controller, provides protection if a battery is inserted backwards into the unit.

b. Crane Receiver. - The crane receiver is a compact unit of modular construction con­sisting of a radio receiver, a vital tone amplifier, a relay driver, ten standard tone amplifiers, four counters, two flip-flop circuits, and various other electronic components.

A 24-volt storage battery is provided to voltage to the radio receiver, tone am-plifier ncn, and the associated relays. These components are used in the remote control of power to the crane, so they obviously require a continuous source of power. Vv'hen the crane

U. S. & S. Div. - 2 - U-5749

is operating, a dynamotor supplies voltage for these components, and also recharges the stor­age battery. The battery may require recharging by an external source if the crane has not been operated within a period of one month.

The modules of receiver box that is shock

crane receiver are all types, and are attached to a crane, a c:;,·~ne receiver case. The base of the receiver

case cov,2:r is bolted to the base. Electrical receptacles and terminals are located on relays, the storage ba:~·teI7, Lnc: the

The cover of th-2 crane receiver box is ana relays of the flip-flop and .. counter circuits are mounted on top of this cover. Various electrical components are at­tached to the bottom of the receiver box cover. The remaining crane receiver modules are mounted inside of the receiver box.

c. Interoosa· Relavs. - The relays are contained iri two sheet-steel cabinets mounted on the crane. Refer to the addc:ndum on the interposer relays for a detailed descrip­tion.
