INTRODUCTION
This manual provides detailed instruction on the installation of GoLifts.Since the introduction of ceiling
mounted patient lifts, the frequency ofinstallations has rapidly increased. This is due to greater
awareness of the risks associated with manual patient transfer and repositioning, which has led to the
enforcement of more strict lifting regulations. Wealden Rehab strives toconsistently provide exemplary
service, design, andinstallation toall of its customers. In an ever more competitive market,itis
important to standardize installation techniques, thus ensuring that the highest standards ofquality and
safety are met.
The guidance given in this manual is intended foruse byarchitects, designers and customers of

ATTACHMENT ACROSS WOOD JOISTS
Attachment across wood joists means that the direction ofthe track line isperpendicular to the
direction of the joists.
If the wood joists are 2” x 4”, The Top-Down Method must beused and the lift capacity cannot exceed
700 lbs. If the lift capacity is greater than 700 lbs.,the Top-Down Method must be used and the
minimum joist requirement is2”x6”.
There are two methods than can beused toattach track across wood joists:
TOP-DOWN METHOD
This method isused when there is workable space above the finished ceiling. Inmost cases, this
method applies torooms that are onthe uppermost floor ofa building, below the roof trusses.

BOTTOM-UP METHOD
This method isused when the joists are located between floors, and where there is noworkable access
above the ceiling.

ATTACHMENT BETWEEN WOOD JOISTS
Attachment between wood joists means that the direction of the track line isparallel tothedirection
of the joists. Ifthe joists are 2”x 4”, either the Top-Down Method or theBottom-UpMethod can be
used, but lifting capacity cannot exceed 700 lbs. If the joists are at least 2”x6”, there are nolimitations
onlifting capacity. If there is workable space above the ceiling, use the Top-Down Method, as
described inthe previous section. Ifthere is noworkable space above the ceiling, The Bottom-Up
Method must be used. When attaching between joists, the Bottom-UpMethod of attachment is
different than described in the previous section.
Bottom-Up Method:
This method isused when the joists are located between floors, and where there is noworkable access
above the ceiling.

ATTACHMENT TO I-JOISTS
Amodern method of construction istouse I-joists, alsocalled, TGI joists, TJI joists or silent floor joists
(examples below) instead of traditional wood joists.
Knowledge of structural I-joists components is crucial when working with these types of joists. There is
only one way todetermine the best way to attach toI-joists. The most important facttoremember is
that the bottom cord ofthe I-joist is never a structural member. Similarly, the vertical plywood portion
of the joist is alsonot structural.
Furthermore, the joist asa whole cannot beattached to until the necessary support isadded. This
means that the I-joist must be“packed” in order to addanysignificant structural pullout value. Packing
is a method commonly used toturn a non-structural member into a structural member by significantly
increasing the pullout value. There are instances when the shape of the I-joist will limit the materials
that can beused for packing. When preparing for a job that involves attachmentstoI-joists, it is always a
good idea to have the manufacturer specs, sothat the packing material can bepredetermined andwill
be ready at the time ofinstallation. It is very costly toshow up at a job and not be able to dothe
installation because the proper materials werenot planned for or packed.
PACKING I-JOISTS:
For every bracket attachment, two T.G.I. joists must bepacked, and the attachment point suspended
directly between the joists. (See Figure 3 – Packing T.G.I. joists) If the attachment point is biased toward
either side of center, the weight will not be evenly distributed among thejoists. This will decrease the
pullout value ofthe member.

A spring (saddle) nut can also be used to secure the threaded rod, as shown below.

ATTACHING TO CONCRETE
There area number of different types ofconcrete andevery individual concrete structure is unique. Itis
very important that the structural details of concrete are investigated andscrutinized before ever
determining if it is suitable for supporting a patient lift system. It is equally important that the
specifications of the concrete anchor being used are known. Many manufacturer specs will provide
pullout values for concrete with a number of different compression values. Compression values are
measured in pounds-per-square-inch (P.S.I.). Itis important to know this value before deciding that the
combination of anchor and concrete will be sufficient for the requirements of the lift.If there is any
doubt as to the adequacy of either the concrete ortheconcrete anchor, consult a structural engineer
before proceeding with the installation.
This manual does not provide instructions on use of different concrete anchors. Refer tothe
manufacturer specs forinstructions for use.
ATTACHING TOA CONCRETE SLAB
Aconcrete slab must beat least 4” thick toreceive a typical heavy-duty concrete anchor. Itispossible to
attach toa thinner slab, but anchor selection will limit the load-bearing capability of the system. Asa
general rule, the concrete should beapproximately three times asthick as theanchor embedment.

ATTACHING TO HOLLOW-CORE CONCRETE & OTHER HOLLOW STRUCTURE:
Chemical anchors are used when the ceiling is constructed of pre-cast reinforced concrete, poured
reinforced concrete, pre-cast concrete sections or Beam &Block Construction (Beam and Block only on
new builds or where access is available tovisually inspect the beam). See Figure 6 – Epoxy Anchors in
Hollow-Core Concrete.
**Always verify load capacities with the anchor manufacturer’s specs before installing**

Figure 7 – Anchoring to Hollow Structures
ATTACHMENT TO STEEL I-BEAMS
As with anystructural member, the specifications andload bearing limitations should bechecked at the
time ofthe site assessment. The most significant determining factor with respect to material and labour
cost isthe span between beams. When surveying a room, the surveyor should note the exact distances
between beams, how many beams are in each room, and where they are located. Insome cases, it may
be necessary to penetrate the firewalls between rooms toattach structural steel between I-beams in
adjoining rooms.
NOTE: There are a wide variety of I-beams clamps available. Refer to the manufacturer specifications
for methods of attachment and load bearing limitations.

ATTACHMENT TO OPEN STEEL WEB JOISTS
There area number of different types andsizes of open steel web joists (OSWJ), each with varying
load bearing limitations. Itis important to know the specifications of the joists before beginning the
installation. When possible, obtain input from an engineer to verify the adequacy ofthe joists for the
purposes of the track system.

ATTACHMENT TO STRUCTURAL WALLS
Wall mounted track systems are typically used when it is not possible tohang from the existing ceiling.
Special consideration is required when fastening wall brackets tothe walls. Wall mounted brackets can
only beattached tostructural load-bearing walls. (See Figure 10– Wall Mount Bracket). There are a
number of different types of structural walls, each requiring a specific anchor type. Extra care should be
taken when preparing toattach each bracket. Use a laser tomake sure the brackets will be level. If the
track system is an XY configuration, make sure that the brackets are evenly spaced between parallel
tracks, astoprevent any potential for thegantry to bind.
ATTACHING TOCINDERBLOCK:
There are three anchoring options when attaching to cinderblock walls.
1. Epoxy anchors can beused inany hollow portion of the block, aswell asthrough the mortar. Refer
to the manufacturer specs for application instructions and cure times. Remember that the epoxy
must cure 100% before a load test can be performed on the track system.
2. Sleeve anchors or lag shield anchors can be used, but are not recommended if the track span
exceeds (a) 92” with Single Track (b) 149” with Double Track (c) 262” with Triple Track. These
anchors are intended for use in hollow blocks.
3. The mounting bracket can be attached by drilling through the structural wall and using a back plate
on the opposite side of the wall. A back plate is simply a small steel plate (1/4” thick) with mounting
holes that mirror the holes on the mounting bracket. The plate should be painted to match the
colour of the wall. Connect the plate to the bracket using long bolts or threaded rod. In the rare
event that the opposite side of the wall is a room that is also being tracked, and the position of the
back plate is a suitable location to mount, a mounting bracket can be used instead of a back plate.
