## Tank top rollers ## Pin style (700525-1) The tank top roller supports the suspension wire rope of a vertically hung staging from the roof of a storage tank. The maximum rated working load is 1,500 lbs. ## Assembly - 1. Verify with the structural engineer that the tank can safely support the rim and tieback loads listed below without permanent damage. - A - these loads include a safety factor of 4 based on the rated load. AB - combine tieback loads if more than one tank top roller is used. [Example - if two are used at 1250 lbs. ea (rated load), 2 x 5000 lbs (tieback load) = 10,000 lbs.) - 2. Position tank top roller as shown on label 700527-1. Maximum overhand distance must not exceed 19.5 in., measured from the suspension point to the edge of the tank with no slack in the tieback line. - 3. Attach the tieback line from the tank roller to the center tank support. Use only industry approved IWRC wire rope with a breaking strength greater than 9,000 lbs. Use only industry approved thimbles and fist grips. DO NOT SUBSTITUTE. - 4. Torque all fist grips to manufacturer's specifications: 30 ft-lbs for 5/16 wire rope; 45 ft-lbs. for 3/8 wire rope. - 5. Proof-load the complete structure at 125% of the rated load. Maximum reach should not exceed 12 in. from edge of tank. - 6. Inspect tank, roller, and rigging for any signs of damage. Retorque all fist grips and recheck the 19.5 in. dimension under the no-load condition. This should be done at the start of each work shift. Do not use the equipment if anything is damaged. <!-- image --> ## WARNING Always use a safety harness and lanyard attached to an independent personnel safety line. Make sure the line is protected from any sharp edges and is secured to an independent safety tieback. Do not use this equipment in any manner other than described here and on label 700527-1. Consult local safety regulatory agencies for additional requirements specific to your area. ## Transfer chain (SA-1002) The transfer chain is i…

## 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…

## Wire rope inspection &amp; service OSHA 1910.28 - Safety requirements for scaffolding. Section (a) (22) Wire or fiber rope used for scaffold suspension shall be capable of supporting at least six times the intended load. OSHA 1926.45 - Scaffolding. (i) (5) Two-point suspension scaffolds shall be suspended by wire, synthetic or fiber ropes capable of supporting at least 6 times the gross rated load (of the scaffold). All other components shall be capable of supporting at least 4 times the rated load. (r) Single-point adjustable suspension scaffolds, (5) the hoisting machines, cables and equipment shall be regularly serviced and inspected, and (8) suspension methods shall conform to applicable provisions of paragraph (h) and (i) of this section. Inspecting the suspension wire rope is very important. Wire rope is a consumable item - each time it is used, it loses strength. The rate at which a wire rope weakens depends on where and how often it is used, how badly it is misused, and the condition of the equipment it is used with. The inspection is to determine, to the best extent possible, whether the wire rope has enough integrity to support a scaffold with the desired safety factor until the next inspection. The wire rope recommended for the Spider equipment in this manual is 6 x 19, fiber core, right regular lay, Seale construction, improved plow steel with a rated breaking strength of 4.26 tons. Never use a wire rope beyond the point where it cannot support 3.75 tons. ## Daily inspection Equipment operators should monitor the wire rope condition daily. Even very subtle changes in the wire rope's appearance could mean it is worn out and should be replaced. The daily inspection should include a visual examination for rust or corrosion, lack of lubrication, broken wires, kinks, crushed spots, or abrasive wear of individual wires. Examine the wire rope guide assembly daily. If it shows signs of grooving, the rigging is misaligned, which can cause rapid abrasi…

## General operating instructions - 1. Assemble the scaffold and rigging equipment according to the instructions in this manual or those supplied with the equipment. (Refer to the precautions in the preceding sections.) - 2. All rigging devices and installations must be able to support the load. An engineer or someone who is trained and capable of determining whether the structure is large enough and strong enough to bear the load should examine structural members. The structure must be able to bear a wire rope load of 4 times the maximum rated load capacity of the hoist. The gross load of equipment, material, and the workers being lifted by each wire rope must not exceed the rated load capacity of the hoist. The structural members intended to support the load must not have cracked or weakened material. - 3. Examine the structure for other safety hazards. - · De-energize and lock out electrical lines in &amp;amp; near the path traveled by the equipment. No live power lines are allowed within 10 ft. of the scaffolding or scaffolding extension. - · Remove obstructions to vertical travel, or clearly identify them to equipment users. - · Locate cranes or other lifts. All equipment users should know the location of all other workers on the structure to avoid coming in contact with them. - 4. Assemble the rigging device to the structure so the suspension line hangs plumb and passes through the scaffold equipment wire rope guide. If the wire rope is pulled off at an angle from the guide, it could wear and become weak. - · Identify and remove other hazards, such as the danger of falling material. - 5. Provide separate rigging attachments for worker safety lines in case the suspension line rigging fails. - 6. With the scaffolding equipment resting upright on the ground directly under the rigging points, connect it to the proper power supply. Place the fairlead side (front) toward the face of the structure. This provides greater stability and minimizes the amount of thrust-o…
