(this manual is intended for use with Schorn Simes Jacks)
Before you begin
Be sure to read this entire manual first. Follow all instructions and procedures in this manual.
Inspection
Inspect all equiptment for damaged, broken, or malfunctioning parts. Be sure all repairs are complete. Before operation be sure that maintenence has been completed.
Employee Education
Be sure all operators and people around the equiptment are familiar with all the parts, pieces, dangers, and hazards.
General Awareness
Identify moving parts and safety hazards before operation of equiptment. Make sure operating area is clear of people and objects before and during operation.
Operating Tips
Do not operate in strong winds. Do not lift, hoist, or carry people with any part of the jacking system. Make sure jacks are not sitting on loose ground, rocks, holes, or any other debris. Never adjust or perform maintenance on any equiptment while in motion. Never allow any persons under any structure being erected by equiptment during operation. Be certain to avoid overhead electrical wires when operating equiptment. Failure to follow Operating Tips could result in serious injury or death.
Jacks, Drives, PTOs, and Mules
Number of Jacks
To determine the number of jacks needed, take the diameter of the bin an divide it by 4 and disregard the fraction. This is the absolute minimum requirement allowable. Secondly, check the weight of the tank to be constructed, including accessories. The Super Simes jacks have a maximum rating of 12,500 pounds, but is generally de-rated to approximately 10,000 pounds per jack due to special circumstances or extra wind loading. The Super Simes Jacks are designed for use on the inside of the grain bin.
Setup
We recommend placing the jacks inside before completing the roof. Once jacks are inside the bin push liftubes above the top of the jack and spin 180 degrees before sliding back into the jack. With the lifttube facing away from the jack the yoke can be slid on and a quarter inch bolt installed into the hole to secure. Position each jack to the inside wall of the bin. The distance between jacks can be varied. On larger diameter bins (over 60' diameter) it is a good practice to place one jack per sidewall sheet at a minimum. When positioning the jacks, try to place each jack between vertical seams so that the vertical seam of the second ring of steel will not end up behind the jack. On bins with 3 stiffeners per sidewall sheet, there should be a stiffener on each side of the jack. The more PTO shafts used on a small diameter bin, the les of an angle the U-joints have to operate at (based on 10' sheets). When approaching a drive unit, a short PTO will be on one side of the drive and a medium drive shaft will be on the other side. Be sure each jack has a PTO connected to both sides.
Synchronizing
The Super Simes Jacks MUST BE SYCHRONIZED before the first lift is made on each bin. This is accomplished by hand cranking each jack down until the jack top pulls away from the collad on the jack top and then crank the jack up until the gap between the top and the collar of the lift tube is the same on every jack. Each jack is equipped with an aluminum shear pin to prevent damage to the gearing. If a jack is not stopped before the bottom of its stroke the pin will shear resulting in the jack no longer able to raise or lower. Refer to maintenence section to replace shear pin.
Connecting the Power Take-Off Shafts
Once the Super Simes Jacks have been synchronized, connect the power take-off shafts. First pull back the outer sleeve of the special quick coupler, slide the coupler of the splined shaft on the base of the jack stand and release the outer sleeve. This will lock the PTO in place. Do not leave an open space between the jacks.
Attaching Jacks to Bin
When the jack is in place at the bin wall use as many existing holes in the bin sheet as possible. Slide the bottom bracket on linkage over 2 bolts on each side of the jack and put the correct size nut on. If bolts used are smaller than 7/16'', a washer may be necessary. Tighten to secure jack to the bin wall.
Anchoring Jacks
With the Jacks attached to the wall and positioned for a straight vertical lift, the jacks should be bolted to the concrete with drill-in, wedge type anchor bolts or equal. Use 3 anchors, located on each side of the base and one in the foot of the jack. After being seated properly, anchors should be put in allowing a 3/4'' gap on the 2 in front and a 1/2'' gap on the foot. It is recommended that a 5 1/2'' minimum length anchor be used. The jacks must stand straight as the bin touches the concrete. Shim as necessary.
Drives
Each 7.5 hp drive has a rating of 110,000 pounds. After calculating the weight of the grain bin and divide by 110,000 to determine drives required. After all of the jacks have been attached to the bin, position the drive between 2 jacks. The drive should be placed so that the PTO is closest to the bin wall. It is best to locate the drive alongside aeration unloading tunnels as much as possible. When using more than 1 drive, run both drives bfore hooking to jacks to check for identical speed and direction of rotation. Low voltage is very damaging to electric motors. Be sure all cords have been properly sized to prevent low voltage.
Mules
Mules are to transfer power from jack to the next when there is a span of more than one bin sheet. When there is a place in the bin that installing a jack is not needed a mule works in its place.
Operation
Lift Cycle
Before beginning the lift cyle, be certain the jacks have been synchronized and properly set. If bin is round and jacks are straight they can be anchored at this time. Be sure all PTOs are connected and jacks are properly attached to the bin wall. On the Super Simes Remote Control Panel, pull the lever to the ON position on the disconnect box. Release the STOP on the control side of the panel and switch the control selector to the remote control setting or panel setting if desired. Switch the direction of travel to the UP position if using the control panel. If using the remote, press the ON button. Sound the alarm twice and push the UP button to start lifting the bin. Raise the bin 18'' and press the STOP button as soon as the entire first hole in the lift tube is visible. On each lift tube pin the jacks with L-pins in the round stand tube below the square tube. After making sure ever round stand tube is pinned, switch the direction of travel to the DOWN position and pull the STOP out if using control panel. If using the remote press the ON button and then the DOWN button to start the down stroke of the jacks. At this point the lift tube supports the bin at this height while the jacks are being run down for the next lift. Run the jacks down 18'' and press STOP when the entire last hole on the bottom of the square tube is visible. On each lift tube, pin the jacks with L-pins in the square tube above the top of the jack. Move the toggle switch on the control panel to the UP position or press the on button with the remote. This process is repeated until the desired height is achieved for the next ring of steel.
Re-Attaching Jacks On Wall
If there are 4 or more crew members, split them into 2 teams for hanging sheets. Each team should start directly opposite one another and work in the same direction. Put all bolts into the horizontal seam of the hanging sheets. Put one bolt into every row on either of the seam, alternating as you go down, creating a zig-zag pattern. The remaining bolts can be put in while jacking the bin up for the next ring. Tighten the horizontal seam when all vertical seams have bolts in them. Use drift pins (punches) to align holes if putting bolts in becomes difficult. At this time position the bin on the concrete as you want it when you are done assembling and raising the bin. It may be necessary to lift the bin several times until you are satisfied with the position of the bin. When satisfied with the position of of the bin and have set it down in its final position, you may have to reposition jacks to align with the holes to re-mount the jacks. Before jacks can be re-mounted to the bin wall you will need to lower jacks to the bottom of the lift cycle. To do this, you will need to lower the jacks until the lifint linkage is loose and no pressure is on the jack. Then un-fasten linkage from the wall and with one hand apply upward pressure on the top of the lift tube. With your free hand pull both L-shaped lift pins from the lift tube and allow lift tube to slide down until it is resting completely in the jack top. Be sure every jack has been disconnected from the wall and then run jacks down until the linkage is at the correct height to connect to the top of the bottom ring on the bin.
Maintenance/Inspection
Super Simes Jacks
Lubrication
The Super Simes Jacks need to be oiled with 1-2 ounces at a minimum once daily in the Jack top oil hole. The gearbox should only require oil after the initial fill if oil is not weeping from the bushings in the gearbox cover. Use only special formulated Gear Silk in Super Simes Jacks. Periodically inspect lift tubes to be sure there is a thin coat of Gear Silk on the square tubing. Inspect lift tube for burrs, knicks, cracks, or any other damage. Check Jack for any damage to the gearbox, the jack top, lift tube, and linkage. If damage is present, replace or repair before jack is used.
Storage
Before Jacks are stored, be sure to propery lubricate jack and all moving parts. Inside storage is recommended. If stored outside a waterproof cover put on over all equiptment is recommented. Plastic sheeting is not recommended since moisture trapped under the plastic condenses leaving high humidity condition, which produces rust rapidly. Water should be prevented from coming into contact with equiptment.
Drives
Lubrication
Periodically check oil and add as necessary. Gear silk is recommended for spline shaft lubrication. Inspect drive periodically for damage. Replace or repair any damage before using drive.
Storage
Before storing, lubricate all moving parts. Inside storage is recommended.
PTO's/Mules
Lubrication
Be sure to periodically grease fitting on PTO shafts and lubricate spline shaft couplers. Mules integrate sealed bearing that require no maintenance. Inspect for damage or parts not working. Replace or repair before using PTO shaft/mules
Storage
Before storing, properly grease fittings and well lubricate spline shafts and couplers. Inside storage is recommended.
