Critical Warnings

Essential warnings regarding severe weather, equipment damage, and operational modifications.

Generator Sizing and Operations

Generator Recommendations for Hoists

Spider's recommendations for generator types and ratings for SC1000 and SC1500 electric traction hoists.

Key Generator Terminology

Definitions of essential terms like Portable Engine-Generator set, Fuel, Governor, Voltage Regulator, and Frequency.

Troubleshooting Poor Hoist Performance

Diagnosing issues like low engine speed, incorrect voltage, low fuel, or blocked cooling systems affecting hoist operation.

Overview

1. Function Description
2. Important Technical Specifications
3. Usage Features
4. Maintenance Features

The provided document describes a checklist and operational guidelines for Swing Stages on Wind Turbine Exteriors, which are suspended platforms used for maintenance and inspection tasks on wind turbines. The system primarily consists of electric traction hoists, a platform, and associated safety and power supply components.

Function Description:

The swing stage system is designed to provide a safe and stable working platform for personnel performing tasks on the exterior of wind turbines. It utilizes electric traction hoists to raise and lower the platform along the turbine structure. The system emphasizes safety through rigorous pre-operational checks, adherence to operational manuals, and specific guidelines for power supply and environmental conditions. It is intended for intermittent platform movement, typically for tasks requiring less than 10 minutes of continuous upward travel.

Important Technical Specifications:

• Hoist Models: SC1000 and SC1500 electric traction hoists.
• Hoist Capacities:
  • SC1500 (Part Numbers 9015, 9016): 1500 lbs
  • SC1500 (Part Numbers 9035, 9036): 1500 lbs
• Voltage AC: 208 VAC for both SC1500 models.
• Amperage:
  • SC1500 (9015, 9016): 9.9 Amps
  • SC1500 (9035, 9036): 6.9 Amps
• Phase:
  • SC1500 (9015, 9016): Single-Phase
  • SC1500 (9035, 9036): 3-Phase
• Minimum KW per hoist: 6 KW for both SC1500 models.
• Power Supply: Designed for 110 VAC and 208 VAC single-phase 60 Hz, and 208 VAC 3-phase 60 Hz.
• Fall Arrest System: Must prevent falls greater than 6 feet. Anchor bolts require tightening to 150 ft-lbs of torque.
• Lifeline: Attached to the top rail bumper plate for platform stabilization.
• Storage Bucket: Must be properly attached with drain holes free from debris.
• Roller Bumpers: Must be secured, turn freely, and be in good condition.
• Hitch Pins: Must be installed and secured with hair pins.
• Generator Requirements: Minimum recommended genset ratings are based on intermittent platform movement (less than 10 minutes of continuous upward travel) and standard ambient conditions. Larger capacity generators are advised under conditions such as ambient temperature over 100°F, relative humidity over 50%, site elevation above 5000 feet, cord length over 250 feet (without a transformer), or continuous hoist operation for more than ten minutes.
• Output Frequency: Must be between 58 and 62 Hz.
• Voltage Operating Range: Critical to verify the hoist's voltage operating range before plugging into the generator to prevent damage.

Usage Features:

• Pre-Operational Checks: A comprehensive checklist ensures all components are in working order and safety protocols are met. This includes verifying hoist manuals, daily inspections, generator requirements, platform weight limits, fall arrest systems, and environmental conditions.
• Hoist Operation: The primary inlet guide must be pushed aside to release the secondary safety brake when de-rigging the secondary wire rope.
• Environmental Considerations:
  • Maximum wind speed limits must be observed; an anemometer is required.
  • Work in unsafe wind or weather conditions is prohibited.
  • Platform de-rigging is required during severe weather to prevent equipment damage.
• Platform Management:
  • Taglines must be secured to structural uprights.
  • The deck must be kept clear of trip hazards; materials should be stored in work buckets outside the deck area.
  • Platform overload is prohibited; the total weight of equipment, workers, tools, wire ropes, power cord, and accessories must not exceed the hoist's rated load.
  • All rollers on the stirrup mast must turn freely and show no excessive wear.
• Power Supply Management:
  • Kellum grips on the power supply must be properly attached to the stirrup.
  • Generator selection is crucial, considering hoist capacity, voltage, phase, and environmental factors.
  • Inverters are described as electronic devices converting DC to AC power, typically quieter and lighter, but with limited power output and susceptibility to sudden load surges.
  • Single-phase power is for most tools; 3-phase power is for equipment with high startup loads.
  • Startup/Run Factor indicates the power required to start an electrical motor, which can be 3 times the run power for a scaffold hoist motor.
  • Power cords must have correct connector pin orientations and match voltage/phase requirements.
  • The generator should not be in "energy saver" mode during hoist operation, as high startup loads can damage both the genset and hoist motor.
  • Low fuel levels can cause voltage and power surges, damaging the hoist.
  • Generator air intake, exhaust, and cooling systems must be unobstructed to prevent overheating and damage.
• Fall Arrest System: Fall arrest anchor points (one per operator) are to be used with shock-absorbing lanyards.
• Hoist Lanyard: Must be attached to the hoist carrying handle and stirrup to secure the hoist in an upright position.
• Platform Modification: Drilling, cutting, removing parts from, or modifying the platform is prohibited. Assistance for different platform needs should be sought from SPIDER.

Maintenance Features:

• Daily Inspections: Hoist daily inspections are mandatory.
• Wire Rope Inspection: Wire ropes must be inspected for kinks, broken wires, or bird caging prior to rigging.
• Troubleshooting:
  • If the hoist is not operating properly, consult the operation manual.
  • For low engine speed/output frequency (outside 58-62 Hz), consult the genset's operator manual or authorized service provider.
  • For incorrect voltage, check the genset's gauge panel or measure with a multi-meter. Adjust output voltage via the genset operator's manual or contact the service provider. A buck or boost transformer may be needed to adjust output voltage.
  • Ensure correct socket/plug alignment and connector pin orientation.
  • Monitor fuel levels and consult genset manuals for consumption rates and refueling procedures.
  • Ensure generator intake, exhaust, and cooling systems are clear to prevent low power output, overheating, and damage.
• Contact Information: SPIDER (877-774-3370) is provided for assistance with platform modifications, troubleshooting, and general support.
