9. OPERATION WITH LIFTING DEVICE
When supplied, a lifting device can be used to help placing and removing stop logs from the frame. It is
basically a beam that travels in the same guide frame than the logs. It has 2 hooks aligned with the 2
handles that are located on each log.
9.1. LOWERING A STOP LOG
1- Hook the lifting device to the chainblock or crane (not supplied)
2- Bring the lifting device over a stop log and pull the rope so that the 2 hooks pivot backwards.
3- Lower the lifting device at the proper height so that the hooks can enter the stop logs handle
when they pivot forward. Let go of the rope. Log is now hooked.
4- Lift the log & device and bring them above the frame. Lower the log into the frame until it reaches
the bottom or the top of the logs that were previously lowered into the frame.
5- Continue to lower the device an inch or two, and then pull the rope to unhook the log. Lift the
lifting device out of the frame with the crane or chainblock.
6- Repeat the steps with the other logs.
9.2. REMOVING A STOP LOG
1- Hook the lifting device to the chainblock or crane (not supplied)
2- Bring the lifting device over the frame where logs are installed. Lower the device into the frame
until it reaches the top log and continue lowering.
3- Hook should engage themselves onto the handles by the weight of the lifting device.
4- Lift the log & device and bring them out of the frame. Bring to place of storage and unhook the log
from the lifting device. Use the rope to pivot the hooks if necessary.
