4.7 Connecting Power Supply to Hoist
Electrical service to the hoist may be power cable, conductor bar with sliding shoe, or festoon system with wheel type
trolleys. Follow ANSI/NFPA 70, state, and local electrical codes including the grounding provisions thereof when
providing electrical service to the hoist.
Make electrical connections using the appropriate wiring diagrams furnished with the hoist (see attachment, wiring
Diagram). Only qualified journeyman electricians shall make any electrical connections, including connections to
collectors or power cord. Power supply to hoist and trolley must be the same voltage, frequency, and phase that are
specified on the hoist and trolley nameplate.
The electric hoist is connected to the power supply by the circuit
breaker Q1 and the safety fuses F1, F2 and F3 (Figure 4.7.1). The
circuit breaker is designed to break off the unloaded electric circuit of
all the poles while carrying maintenance and repair activities. It is
recommended to install the circuit breaker in the electric board of the
working place or mount it in some inaccessible place
.
The power supply cable is connected to the hoist as shown on
Figure 3.10. The three phases of the power supply cable 1 are
connected to terminals, marked as positions 10, 11 and 12 and
marked with symbols L1, L2 and L3.
The rest connections between the separate electric modules are made by the manufacturer as follows: cable to the
electric motor of the hoisting unit, cable to the control switch 4, cable to the load limiter 5. Terminals 6 represent the
connections of the power supply circuit, terminals 8 - of the operating circuit. Separating plate 7 is placed between the
terminals of the power supply circuit and the operating circuit.
Before energizing the power supply, and inspecting and testing the
hoist prior to initial operational use, check that all electrical
connections are in accordance with the wiring diagram located in
hoist control enclosure. If the power supply that will be connected to
the hoist is not the same as shown on the hoist serial number plate,
DO NOT connect power supply to hoist.
ASME B30.16 requires that all new, altered, or modified hoists be
inspected by a designated person prior to initial use to verify that the
equipment and installation comply with applicable provisions of the
standard. Such an inspection should be performed at this time, using
ASME B30.16 as the basis for inspection procedures.
Disconnect power and lockout disconnecting means before connecting power supply to hoist.
Only a qualified electrician should connect the power supply to the hoist.
