Pull the lamp rope with the reserved rope
The reserved rope and the pull light rope shall be connected with a
dead buckle to ensure that they will not fall off accidentally, and
the nodes shall be wrapped with adhesive tape. Especially for the
rope end of the lamp rope, it is easy to cause the inner membrane
to scratch during the dragging process.
In the process of pulling the lamp rope down into the material with
the reserved rope, it must be operated when the material is
inflated. Otherwise, it is easy to cause inner membrane damage.
Lower lamp
Under the light of the link is the most cause intimal damage. Be
careful. Before lowering the lamp, check the lamp wheel, lamp body,
and connecting wire for burrs and resin. If any, clean it and treat
the wheel smoothly. If it is a headlamp wheel, it is recommended to
wipe a small amount of grease to reduce the friction of the
material's inner membrane when the headlamp is lifted and lowered.
During the process of lowering the lamp, it is necessary to ensure
that the material bulges up and the lamp enters the material
smoothly without obstacles. If it cannot enter smoothly, it is
necessary to find out the reasons for the obstacles. It is not
allowed to drag or kick. Most of the inner membrane damage occurs
at this time. The lamp shall be pulled into the material as far as
possible, and sufficient length shall be reserved for the binding
head for easy operation to avoid hindering the lifting of the
headlamp.
