Design, Manufacture and Installation of Theatrical Equipment WorldwidePowerLift ®Inspection Check ListPRODUCT USE REQUIREMENTSThis checklist is provided as a tool for use by a qualified person while inspecting PowerLift machinery. Although an attempt has been made to include all of the most important points of inspection, no such list can anticipate the particular circumstances of every installation. It is the responsibility of the qualified person to make a reasonable effort to identify hazardous conditions not mentioned herein and formally advise the owner to take corrective action. This check list is primarily for inspecting the hoist machinery. Loft blocks, cables, battens, and all other parts of the rigging system must also be inspected.IMPORTANT SAFETY INFORMATION• See Identification Label attached to controls enclosure on each unit for model number, speed, and capacity information.WARNING! Improper installation or maintenance can cause the load to fall.• Equipment must be inspected at the time of installation and annually thereafter. Individual applications may require more frequent inspection and maintenance. • Do not substitute or modify components provided with this equipment. Use only parts provided by JR Clancy.• Remove the load from the hoist before disassembling.DANGER! Electrocution Hazard• Remove power source before opening electrical panels.• Electrical equipment must be serviced by qualified personnel only.WARNING! Moving parts can cut or crush.• Keep body parts away from machinery in motion. • Remove power source before working on machinery.INSTRUCTIONS FOR USE1. Prior to inspection, obtain and review a copy of the PowerLift Maintenance Manual for the hoist configuration being inspected. Contact JR Clancy if the correct Maintenance Manual cannot be located.2. Identify the channel number of the machine to be inspected and write it in one of the boxes at the top of the check list. Duplicate the list as required for larger systems.3. Inspect each of the items on the checklist and verify that the machinery is serviced and adjusted according to the requirements of the maintenance manual. See the manual for questions about specific part names and adjustments. Remove the covers from the machine as required.4. Replace the covers and repeat the process for each machine at the site.5. Inspect the theater. Make sure that capacity labels, safety signs, and dealer contact information are in place.6. Make contact with the authorized person at the theater and make sure that all of the manuals and the service log are available for use.7. File copies of the check lists in the owner’s service log along with any recommendations for service. Complete the attached Certificate of Inspection and fax or mail a copy of the checklist to JR Clancy.PowerLift Inspection ChecklistVenue Name:_____________________________________Date of Inspection : _______________________Channel NumbersCheck machine covers Machines with moving parts within 106 inches (2.7m) vertically from the floor and less than 60 inches (1.5m) horizontally from a safety barrier must be fitted with machine covers. Otherwise covers may be omitted at the discretion of the customer.Roll pins are in place at each end of beam.Beam flanges where the machine is attached are less than 8” (20 cm) wide and less than 1” (2.5cm) thick. Flanges are at least 4” (10 cm) wide and 1/4" (6 mm) thick.Check mounting clampsClamp rods are tightened. Thrust plates installed on both ends of hoist. Jam nuts are installed and tightened.Sheave fleet angles are within 1.5 degrees. Cables do not rub side plates of head or loft blocks. Cables are not twisted.Only one line wraps more than 20 degrees around the sheave of the beam mounted loft blocks(if provided). That line is in the 3rdgroove as marked.The drum/head block fleet angle matches the helix angle of the drum. Checkblocks and reevingWire rope is free of kinks, corrosion, distortion, and broken strands.Cable keeper roller installation matches the directions in the Maintenance ManualExposed parts of drive shaft are clean and lubricated. Drum screw is clean and lubricated. Rubber protective band has been removed from the reducer breather valveFor electric load brake, the manual release bolts of the secondary load brake have beenremoved. The gap between the load brake magnet and armature measures 0.9 mm (0.035”) For mechanical Weston Brake, the bottom of the dust groove in the brake pads is visible on all pads of the brake. The disks of the Weston Brake are free from dirt and oil.Check machineryThe mounting position on the gear reducer name plate matches the actual mounting position of the PowerLift. No apparent oil leaks. Oil level is correct for the mounting position. Replace or lab test gearbox oil every two years.Control enclosure covers are in place. No missing fasteners Strain relief connections are tight.Power plugs are twist-locked into receptacles. Control plugs are latched into receptacles. Check electricalUnused control plugs are closed and latchedLimit switch brackets and activation arms are in good condition and not bentHard limits are set and checked. For electric load brake, 6“ (15 cm) from any obstruction. For mechanical Weston Brake, 6” (15 cm) for fixed speed units, 14” (36 cm) for variable speed units. With the machine on down hard limit there are at least three dead wraps on drum for each line Machine runs smoothly throughout entire range of travel Limit switch locking nuts are tightenedFor electric load brake, when hoist stops after lifting batten, motor brake engages before load brake engages. When the hoist is moving the batten, the load brake is open and does not rub Check operation and limit switchesFor mechanical Weston Brake, when hoist is lifting batten, motor brake stops the load before the load brake pawls engage. When the hoist is lowering batten, the load brake engages consistentlyCapacity labels are in place on each batten and match the machine capacity on the hoist Identification LabelMotorized rigging safety sign is installed and dealer contact information has been filled in Jumper has been removed from service light timer. Timer is reset and light is off.Check the availability of safety information materialsOwner has copies of the Installation, Operation, and Maintenance Manuals, and Service Log.Design, Manufacture and Installation of Theatrical Equipment Worldwide J.R.
