Magnet Access and Rigging

The magnet is very heavy and fragile, thus requires special consideration during delivery and
movement  to  its  final  installation  point.  The  other  components  of  the  spectrometer  system
(console,  options,  etc.)  can  typically  be  removed  from  the  trucks  with  forklifts  and  are
positioned  in  the  NMR  lab  with  a  pallet  jack.  Specifications  for  these  components  are  also
included in this chapter for planning purposes.

4.1

Considerations for Off-loading on Site

When planning for offloading the magnet and console during delivery, the following factors
must be considered:

Delivery Area

There must be sufficient space in the driveway or parking area for the overhead crane (or
forklift) and for the delivery truck. There must also be sufficient leveled area for uncrating the
magnet and other crates.

Transport Weight

The transport weight and size of the magnet system, console and their respective crates will
affect the choice of equipment required for offloading and movement of the magnet.

Loading Dock

The

size and overhead clearance

of the loading dock will influence the choice of forklift,

crane, or other rigging equipment required to off load the magnet and system crates.

The

elevation

of the loading dock relative to the laboratory will determine if a crane is

required, or if an elevator is needed for the transportation of the magnet from the loading
dock to the laboratory.

The

load bearing capacity

of the loading dock must be sufficient for the system. Refer to the

transport weights of the magnet system, console, and accessories listed in the chapter.

If height/width restrictions require the magnet to be removed from the pallet (e.g. to pass
through a doorway), rigging equipment will be needed both on the loading dock and inside
the lab.

Equipment Requirements

All rigging equipment required to off-load the magnet system must be selected to handle the
size and transport weights of the system.

Generally a

pallet

is integrated in the magnet crate. The top and sides of the crate are

removed or lifted off the magnet, leaving the pallet under the magnet for transportation into
the lab.

Crane

: For larger magnet systems, a crane meeting the load requirements for the specific

magnet may be required to lift the magnet off the truck, place it on a flat surface for uncrating,
and for lifting the magnet again for placement on air skates or a pallet.

Forklift

: It may be feasible to use a forklift to pick the magnet from the truck and lower it to a

flat surface for uncrating.

Pallet Jack

: If a loading dock is available, it may be possible to roll the magnet off the truck

using a pallet jack.
