If this is not possible, due to lack of space, insert the chain through the elevator head outle
t (see drawing below), insert the complete chain down the channel. Then insert half of the
chain into the return channel, so the chain is evenly distributed in both channels.
Block the chain with a rope or wire, and pull one end of the chain around the bottom
sprocket and lift it up to the inspection door. Check the chain length
(loosen the tensions bolts on the elevator head). If the chain needs shortening, it can be
disassembled with a thin chisel. Assemble the chain – use only new clips in the connector
links. Tighten the chains with the bolts on the elevator heads with a few mm play at the
lower sprocket.
