Includes sprocket, 3' of #41 roller chain, 26' of hand chain, 1 chain keeper and a 1/4" key
CHAIN HOIST INSTALLATION:
Shaft Mounted units (1:1, JR-ST, JR-RD, JRG):
Install Unit onto Door Shaft.
Sprocket mounted to Rolling Door on JR-RD or sprocket on JR-ST need to align with the small 9 tooth sprocket.
Secure from sliding along the shaft with set screws and shaft collars as applicable (use shaft keys where needed.)
Install Roller Chain on JR-ST or JR-RD (the roller chain has a connector link to split chain and reconnect.
Install bracket to wall on JR-ST- or JRG if desired to keep unit from swinging.
Wall Mounted Units (3:1 models, 4:1 models):
Install Sprocket onto door shaft with key and set screws.
Install the main unit to the wall so that the roller chain will be free of slack when installation is complete (shorten roller chain if needed).
If not already completed during the previous step, install the roller chain between the main unit and sprocket on the door shaft (move the sprocket on the door shaft if necessary to ensure the sprockets are aligned).
Thread the hand chain around the pocket wheel and let it hang (extra chain may need to be purchased in doors in excess of 14ft or vertical lift or high lift doors).
Adjust the length of the chain so that the loop will hang around 1ft off the floor.
With the chain hanging freely, a link on the hand chain will need to be ben open and then closed again to complete the look. This can be accomplished with two sets of pliers
Install the chain keeper on the wall at a reasonable height and location so that the chain will be clear of the opening when engaged in the keeper.
QUESTION: how is this product installed? No information on it. by None N 10/27/2015
ANSWER: I will look for installed paper work and see if I can send it to you. You small gear goes on the main shaft. the main unit goes on the wall below or above the gear you put on the main shaft. Make sour you get a board wide 12" and 10 foot long to go on the wall before you install the main unit. then the chain goes on the gear and the main unit. this is how it work hope it help you. by kenneth k a
ANSWER: On my door the old unit was stitchwelded to the door frame and the welds had to be carefully cut with a disc grinder and then smoothed over to provide a flat enough surface for the new unit to be installed. In my case the bicycle chain going to the door was a different length so I had to plot the position of the new unit by hanging it from the chain and ensuring that the two sprockets were parallel and in line with each other. Then the unit could be tack welded in place and then stitched. There is no need to overdo the welds. Three one inch stitches are enough: one on each side and one along the bottom. The hardest part of the job is getting the smaller chain sprocket off the door spindle if its frozen to the shaft, but if its still in good condition you can simply reuse it as-is. by Sam H a
QUESTION: can this chain hoist be instaled on either side of door? by None N 1/4/2014
ANSWER: yes by T F a
ANSWER: Yes. The unit is reversible. by Sid H a
ANSWER: Must be installed on whichever side of the door that has the shaft it is intended to turn. It is a much more "stout" apparatus than I expected, mine turned a burly job into child's play. by Phil M a
ANSWER: Don't see why not. I actually use mine to open the roof vent in a greenhouse, and it is located in the middle of the drive rod. Need enough rod sticking out the end to align the sprockets and mount the housing on the wall. by Victor M a
ANSWER: yes. You may have to disassemble and reassemble to change position of the sprocket. This is very simple. by ARTHUR S a
ANSWER: Yes it can. by Lloyd B a
QUESTION: I am wondering if there is set screws on the gear my torsion shaft has no key slot? by None N 5/4/2013
ANSWER: Yes, the driven sprocket has two set screws. by Victor M a
QUESTION: I am interested in getting this, but I am not sure the diameter of the shaft. Is there an adapter that will make it fit both sizes? I cannot get to the door without driving a long distance. It is in a remote area that is far from hardware stores. by John H 11/18/2012
ANSWER: I don't think an adapter exists, but just buy 1 complete set with say the 1" bore, then you can buy an 1"1/4 bore sprocket a la carte separately.and ask them if you can return the one that doesn't fit. But the 1 1/4" bore sprocket is only another $29, so not the end of the world. by Lowe R a
