Rice Lake MSI-4260 Port-A-Weigh - Manual (Page 13)

Introduction 9
1.8 Installation
The MSI-4260 features a heavy duty, cast aluminum enclosure rated at NEMA 4 IP
66. It installs easily by hanging it on the crane, using properly sized shackles.
Note
Please refer to MSI’s brochure, “Crane Safety” when installing

model MSI-4260 .
One of the most common installation problems is using an oversize shackle or too
large a hook to interface with the MSI-4260. This can cause off center loading and
stress points that will reduce the life of the lifting eye or hook.
Use the appropriate interface hardware for the capacity of the scale.
• If your interface hardware does not fit properly, MSI can supply the MSI-4260
with oversize lifting eyes or shackle interfaces.
• If the crane hook is too large to fit in the lifting eye with single point interface,
then install the scale using adaptive rigging.
• If multiple attachments are needed, use a shackle or ring to attach the multiple
lines to thus keeping a single point attachment to the scale.
WARNING
Important
Single point attachments are necessary to ensure the safety and
accuracy of the scale system.
Regular maintenance inspections of the lifting system should be
performed to ensure safety. Pay particular attention for signs of
stress on any element in the load train.
