Section 5 – Procedures

5.2-2 Gate Spring Hinge Adjustment

1. The tension of the spring hinges should be
such that when the gate is opened halfway and
released, it will close fully and latch.
2. To adjust the tension of the spring hinges, first
remove the safety locking screw of each hinge.
Retain the screws for reinstallation later.
NOTE
Adjusting the tension on the spring hinge is a two
handed operation .
3. To increase the tension, insert a 5/32" hex wrench
in the screw socket. Turn the wrench clockwise
to desired tension as well as aligning the locking
screw hole. Hold the wrench in place, maintaining
the selected tension, while reinstalling the locking
screw.
NOTE
Make sure the holes inside the hinges are aligned
before inserting the locking screw .
4. Adjust all the other spring hinges on the gate so
they have the same tension.

5.2-3 Railing Maintenance and Repair

Skyjack MEWPs have been designed to make sure
compliance with the relevant design standards
applicable for that particular unit at the time of
manufacture. As such, any repairs made to the
guardrail or basket structure need to make sure this
compliance is not compromised and must return the
structure to its original condition.
Any damage must be repaired by returning the railing
assembly to its undamaged state. Damage includes,
but is not limited to, the items listed below:
bent/deformed guardrail sections
▪
cracks or broken welds in railing sections
▪
damaged pin connections
▪
missing pins or broken pin lanyards
▪
missing railing hardware
▪
loose or missing parts
▪
additional holes in guardrail sections other than
▪
those approved by Skyjack
Additionally, the guardrails must be properly
positioned and secured, and the entry gate must be in
good working order.
The strength of the guardrail system, and therefore
its ability to provide fall protection for platform
occupants, depends upon the design being secure
and undamaged.
Skyjack railings are designed for modular
replacement, and Skyjack recommends replacement
of any damaged railing section. Skyjack-approved
replacement parts will meet this requirement.
