Chassis Lifting Guidelines
•
Before moving the device to a site, ensure that the site meets the power, environmental,
and clearance requirements.
•
Before lifting or moving the device, disconnect all external cables and wires.
•
As when lifting any heavy object, ensure that most of the weight is borne by your legs
rather than your back. Keep your knees bent and your back relatively straight. Do not
twist your body as you lift. Balance the load evenly and be sure that your footing is firm.
•
Use the following lifting guidelines to lift routing devices and components:
•
Up to 39.7 lb (18 kg): One person.
•
39.7 lb (18 kg) to 70.5 lb (32 kg): Two or more people.
•
70.5 lb (32 kg) to 121.2 lb (55 kg): Three or more people.
•
Above 121.2 lbs (55 kg): Material handling systems (such as levers, slings, lifts and
so on) must be used. When this is not practical, specially trained persons or systems
must be used (riggers or movers).
