3.3 ELECTRIC POWERED HOIST
3.3.1 General
For typical installation on a scaffold and for reeving instructions, see Section 3.5
WARNING: An electric powered Sky Climber hoist shall NOT be used in an explosive
atmosphere.
An explosive atmosphere is one in which flammable gases or vapors or small particles are or may be
present in the air in quantities sufficient to produce an explosive or ignitable mixture.
3.3.2 Power Supply
Check technical specifications for minimum power requirements (see 2.2.1).
CAUTION: The motor may overheat if the measured voltage at the motor during operation is less than
90% or more than 110% of the voltages shown on the motor data plate.
On exceptionally long drops, locate the power source in the middle of the drop, thereby reducing the
amount of power cord required.
3.3.3 Low Voltage Operation
If a problem in motor performance exists when operating two hoists due to low voltage, the use of a
booster transformer or of a separate power cord for each hoist is recommended.
3.3.4 Power Cords
Because of varying platform load, source voltage and electrical system impedance, it is impossible to
recommend optimum electric cord wire sizes, but Sky Climber recommended supply cable will be
satisfactory in nearly all cases. Extremely long drops may necessitate the use of a voltage booster
transformer or location of the power source in the middle of the drop, thereby reducing the required
power cord length.
IF A BOOSTER TRANSFORMER IS NEEDED, CALL YOUR SKY CLIMBER REPRESENTATIVE.
The power cord must be secured to the swing stage by strain relief devices or other means to prevent
the connector from pulling apart. When two power cords are used in series, include strain relief devices.
Make sure the power cord length is sufficient to permit free travel of the platform without applying undue
strain to the cord strain relief.
When finished for the day, make certain the power cord is disconnected at the main outlets. Protect
power cords from rain and water at all times.
Do not attempt to alter any connectors to fit power outlets. Do not use deteriorated or contaminated
components.
