.1 Loading/Unloading and Hoisting (Diagram)
(1) Units should be loaded and unloaded carefully to avoid causing damage to unit components. Use a
crane to load and unload units and use a forklift for short-distance transportation. A skid can ensure
that the weight of units is evenly distributed on the base. In addition, three to six steel rods can be
placed under the unit base to help slowly move the units, as shown in the following figure.

(2) To hoist the units, pay attention to the following instructions:
Choose a suitable crane based on the unit's weight (buy insurance for it if possible).
Hoist the unit by using the method shown in the following figure. The steel rope shall wind the
lifting hook one circle to prevent danger due to steel rope slipping when the weight is unbalanced.
Use an enlargement pole to prevent sling damage to the unit.
Strictly abide by the local safety regulations during hoisting. Only relevant personnel are allowed
within the construction area. It is forbidden to stand under the crane or the lifted units.
