## Electric power supply The available power supply (115 or 230 volts single-phase at the control assembly plug) must be maintained when the staging is lifting its maximum intended load. The model designation plate indicates the required voltage. The power supply locking plug on the control assembly will also indicate the required voltage. If running the stage from a motor generator, use a minimum of 2,500 watts per stage. Do not use demand governor. If a transformer is used, use no less than 1.5 KVA. Be certain that the output voltage is correct and properly fused. ## Inspection The operator can tell if the stage is not getting enough power. If the motor pulsates or makes unusual noises while operating, further inspection by a trained and knowledgeable person is needed. Every 30 days or during installation, a trained and knowledgeable person should inspect the stage and power supply. - 1. Examine the plugs on the stage and supply cord to make sure that they are correct NEMA standard for the voltage being supplied. The plugs should be the correct voltage and be rated at 20 amps for G.E. and 15 amps for DYNA motors. - 2. Examine the plugs and rubber boots for any signs of damage that might prevent correct use. - 3. Use as short a supply cord as necessary. Use wire no smaller than 10 gauge. - 4. Always connect the supply cord to a good source of voltage and make sure it is protected by a 20-amp fuse or circuit breaker. Make sure that no other machines are drawing from the same supply. This may cause a motor to burn out due to voltage fluctuations. - 5. Check voltage and current at the control while the motor is running and lifting its maximum intended load. Voltage should not vary from the rated voltage by more than 10%--a 10% reduction in voltage results in a 20% loss of power. Large voltage fluctuations can cause the motor to burn out. Keep wire rope length at a minimum if a low voltage condition exists that cannot be easily remedied. ## Troubleshooting the ele…

## Transmission Both the air and electric units have a worm gear transmission. <!-- image --> ## Inspection Every 30 days (sooner if there are oil leaks) inspect the oil level in both sections of the transmission through the inspection hole. If the level is below the hole, fill with Mobil SHC 634 cylinder oil. Use no substitutes. At the same time inspect the bronze gear. The width of a new gear tooth is approximately 1/16-in. If the edge of the tooth is getting sharp, replace the gears. Contact your local Spider representative. - 1. On electric models, lay the stage down on the fairlead side and remove the drain plug. Look at the outer edge of the gear teeth. The sharper the edge, the thinner the tooth. (For an easy check, put the worn gear next to a new one.) - 2. On air models, inspect the bronze gear from the filler hole. Tip the stage to keep oil from draining out. Every 12 months (sooner, if needed) drain the oil from both sections of the transmission and replace with new Mobil SHC 634 cylinder oil. Use no substitutes. One quart will fill both sections of all hoists except the ST-26, which needs about 2 quarts. ## Overload switch The overload shut-off switch limits the amount of load that can be applied to the wire rope. This keeps a safety factor on the wire rope and rigging and prevents overworking the hoist motor. ## Inspection Every 30 days, or before installation on a new job, the overload shut-off switch should be inspected for proper operation by someone you or the employer knows is trained and knowledgeable: - 1. With all the wire rope stored neatly on the drum and the free end rigged to a beam of adequate strength, load the staging with the rated working load as shown on the load rating plate. - 2. When connected to a proper voltage or air supply, the staging should lift the load. - 3. With the addition of another 100 lbs, the overload shutoff switch should prevent the upward travel of the stage. ## Testing the overload switch using the tes…
