9 Assembling DANGER Only qualified maintenance personnel or experts are allowed to assemble and disassemble the electric chain hoist. Prohibited Assembly or disassembly of the hoist by incompetent personnel may result in death or serious injury. Installing a Chain Container Preparation for Assembling To facilitate mounting the chain container, hang the hoist body. Check that the stopper and the cushion rubber are attached to the third link from the end of the no-load side chain (the side without the Bottom Hook). Assembling The two types of the Chain Container are provided: canvas and steel This manual describes the method to combine the canvas Chain Container with the body of the electric chain hoist. Refer to the separate Mounting Manual of the Steel Chain Container" for the steel Chain Container. Mandatory Mandatory DANGER The each type of Chain Container has the capacity to store the specific amount of the Load Chain. Use the Chain Container in correct capacity. An chain overflow from the overstored container or a drop of container improperly installed on the hoist can cause quite dangerous situation, resulting in fatal or serious injury. Failure to have the maintenance personnel install the Chain Container may cause fatal or serious injury. Before installation of the container, please also check the container capacity of the hoist and lifting height as shown on the container. CAUTION en storing the Load Chain into the Chain Container, put the end of no-load side chain first and then store the rest of the Load Chain in order. Failure to comply with these instructions may causes bodily injury or loss of property.

11 Checking rails used for the trolley, and adjusting the collar Although the product is shipped in conjunction as far as the order of the hoist and trolley is made, it is necessary to adjust the collars to the width of your rail. en a rail width is specified upon order, the collars arrangement is made at shipment. However, if you change to a different rail width, make correct collar adjustments as explained in this section. Rail and wheel profile In the conjunction with the motorized or manual trolley, the profile of the trolley wheel and the rail should meet. Check the profile of both the rail and the wheel. For I beam For H beam Rail spacer arrangement Improper spacer arrangement could result in missing, irregular running or dropping. Make correct adjustments of the trolley spacers to the rail width as shown in the following the table.
