written. Should any such legislation or practices change or
be “enlarged” upon then due consideration must be
taken. Various standards have been used to assist in
compiling this document and will be listed where
applicable.
According to ASME B30 Standard the use of trolleys is
subject to hazards that cannot be overcome by
mechanical means but only by the exercise of
intelligence, care and common sense.
It is therefore essential that personnel involved in the
construction, operation, installation, inspection, testing,
maintenance, repairing and using Elephant Lifting Products
trolleys must be careful, competent, trained, physically
and mentally qualified in the safe operation of this
equipment and handling of loads.
Serious hazards include but not limited to, overloading,
improper or inadequate maintenance, dropping or
slipping of the load caused by improper hitching or
slinging, obstructing the free passage of the load and
using equipment for a purpose for which it was not
intended or designed.
The above can lead to fatal consequences. Operators of
Elephant Lifting Products trolleys are also under obligation to
ensure safe and hazard-free operation. This can be
achieved through the following measures:
 Keep the operation manuals available at the trolley
operating site,
 Performing regular training,
 Performing regular inspections (at least once
annually),
 Implement an inspection log and make regular
entries,
 And regularly check personnel for safety and hazard
awareness during work.
Elephant Lifting Products fully realizes the importance
of proper design factors, minimum and maximum sizes
and other limiting dimensions of the trolley and its
fastenings, chains, sprockets and similar parts all of
which are designed with safety in mind.
The various conditions of the equipment or material can
vary depending on the environment they are used in
which may cause corrosion or wear and any other
variables that may arise in each individual application. It
is in the light of this that the trolley(s) must be maintained
and repaired under the supervision of a competent
person:
(a) Who is qualified by virtue of his knowledge, training,
skills and experience to organize the work and its
performance;
(b) Who is familiar with the legal requirements which
apply to the work to be performed;
(c) Who has been trained to recognize any potential or
actual danger to health and safety in the performance
of the work.
The instructions given in this manual must be interpreted
accordingly and sound judgment used in determining their
application. It is intended to help the operator to become
familiar with Elephant Lifting Products trolleys and
how to use them properly. Observance of the
manual helps to avoid hazardous situations, to
reduce repair costs and downtimes and to ensure
the specified service life of the Elephant Lifting Products
trolleys.
•Always keep this manual readily available at the

3.2 Safety Summary
1 Do not use these trolleys or any equipment attached
to it for lifting, supporting or transporting people and
lifting or supporting loads over people.
•Elephant Lifting Products trolleys are designed
to provide a MINIMUM of 5 to 1 safety factor. It is
the responsibility of the customer to ensure that the
structure to which a trolley is attached and any load
attaching device(s) used in conjunction with a
trolley(s) can handle the static and dynamic load(s)
when the trolley is lifting
and lowering the rated load. If in doubt, consult a
registered professional structural engineer.
•If a hoist is to be used in conjunction with the
trolley, ensure that a hoist having a rated
capacity equal to or less than the capacity of the
trolley is specified.
2 Lifting equipment is subject to different regulations in
each country. These regulations may not be
specified in this manual. Whenever a conflict arises
between the contents of this manual and any other
applicable legislation, standard or procedure, the
more stringent of the two must be applied.
The Occupational Health and Safety Act and Mine Health
and Safety Act and other recognized safety sources make
a common point: Employees who work near cranes or
assist in hooking on and arranging a load(s) should be
instructed to keep out from under the load.
From a safety standpoint, one factor is paramount,
conduct all lifting operations in such a manner that if there
were an equipment failure, no personnel would be injured.
This means keep out from under a raised load and keep
out of the intended path of any load.

7 Safe Operating Instructions
1. Before each use or shift, the operator should inspect
the trolley for distortion, wear and damage.
2. If inspection indicates that a trolley is damaged, it
should never be used. Replace any item indicating
damage, distortion and/or excessive wear.
3. To avoid an unbalanced load which may damage the
trolley, operate the trolley when the load or hoist (if a
hoist is used in conjunction with the trolley) is
centered under the trolley. Position the hanger shaft
at the centerline of the trolley and beam using
properly installed spacer washers. Do not “side pull”.
4. If a hoist is to be used in conjunction with the trolley,
ensure that a hoist having a rated capacity equal or
less than the capacity of the trolley is specified.
5. Do not use these trolleys for lifting, transporting
people or supporting loads over people. Make sure
people or any obstruction are clear of the load path
before traversing the load and trolley.
6. If multiple trolleys are used together at the same time,
avoid collision or bumping of trolleys and do not ram
trolleys into the end stops. Improper and careless
operation can result in a hazardous condition for
operator and load.
7. Ensure stops are securely installed at both ends of
the beam prior to using trolley.
8. Ensure that stops are installed to prevent the trolley
from running off either of the open ends of the beam
track when the trolley is being installed over the open
end of the beam.
9. On a hand-operated trolley, the stops should engage
parts of the trolley other than a wheel. If a stop
engages the tread of the wheel, its height shall be no
less than the radius of the wheel.
10. Do not join a hand chain by inserting a bolt between
links as this may cause jamming of a hand chain with
the hand wheel sprocket.
11. Do not swing a suspended load.
12. Ensure that trolley wheels’ ride on the top surface of
the lower flange of the beam.
13. Install manual chain hoists so that hoist hand chain is
on opposite side of trolley hand chain.
14. When operating the trolley, keep the load as close to
the floor as practical to make people aware and keep
clear of any load the trolley is supporting.
8 Installation
The installation of the Elephant Lifting Products
trolleys shall be in accordance with the qualified
persons recommendations described above “Personnel
Competence” on page 2.
Adjust trolley width before installation. Refer to Figure 1
below along with instructions to position spacer washers
for measured beam flange width (W).
Figure 1: Push Trolley
Instructions:
1. Measure the beam width (W) and add 2-4mm to this
amount for clearance between the wheel flanges to
allow 1 to 2 mm of clearance per side (“A” in the
figure);
2. Remove the locknuts from the crosshead and adjust
the width of the trolley by shifting the spacers
accordingly. There are two different thicknesses of
spacers that allow for adjustment in 1mm increments.
Ensure that the amount of spacers on either side of
the crosshead are the same. Spacers not used
between the side plates should be fitted to the shaft
between the side plate and the lock nut. Ensure that
the suspension plate (if fitted) or the groove in the
crosshead is central to the side plates;
3. Fully tighten the locknuts and re-check the clearance
between the wheel flange and the beam.
Upon completion of installation, perform initial operating
checks, Section 10.1 and ensure familiarity with “Safe
Operating Instructions”, Section 7.
NOTE: Rounded wheel tread is suitable for taper and
parallel flanged beams.

9 Clearances
Under all operating conditions, clearances between
beams, trolleys operating at various levels and potential
obstructions, shall be maintained.
Where passageways or walkaways are provided on
the structure supporting the trolleys, obstructions
shall not be placed so that personnel will be
jeopardized by movements of the trolleys.
Clearances shall be provided at the curves of the beam
to allow for the swing of the load when the trolley is
negotiating the curve. The amount of clearance shall be
determined by considering the size, weight and speed of
the trolley and track curve radius.
10 Operating Conditions
The four most important aspects of trolley operation
are:
1. Follow all safety instructions when operating the
trolley.
2. Ensure that only people instructed in safety and
operation of these products operate the trolley.
3. Inspect each trolley on a regular basis and scheduled
a maintenance program.
4. Always ensure that the weight of the load and rated
capacity of a hoist (if it is to be used in conjunction
with the trolley) are equal or less than the capacity of
the trolley assembly. Do not overload.
10.1 Initial Operating Checks
1. Upon completion of trolley installation, ensure the
side plates are parallel to the beam.
2. If a hoist is used in conjunction with the trolley ensure
that the hoist and load are centered below the trolley
and beam.
3. Lift a load equal to or less than the rated capacities of
either the trolley or hoist a few centimeters or inches
off the floor. This is to ensure that all parts of the
trolley are in working order. If parts of the trolley are
dropped, they can cause severe injury or damage.
4. Ensure that the rail stops are securely installed.
5. Operate the trolley along the entire length of the
beam.
6. Inspect trolley performance when raising, moving and
lowering test load(s). Trolley must operate smoothly
prior to being placed in service.
11 Lubrication
Trolley wheels are equipped with sealed bearing which
require no lubrication.
11.1 Geared Trolley Wheels
Trolleys shall be stationary while lubricants are being
applied. Lubricate exposed trolley drive pinion and wheels
teeth with grease as often as necessary to keep the teeth
liberally covered.
If the grease becomes contaminated with dirt or other
abrasive material, clean off old grease and apply new
grease. For temperature -29o to 10o C (-20o to 50o F) use
M2 EP 1 grease or equivalent grease. For temperature -
1o to 49
o C (-30o to 120o F) use M2 EP 2 grease or
equivalent grease.
•When greasing pinion and geared wheels make
sure excess grease is removed from trolley
wheels riding surface and track of the beam.
•Failure to keep beam track and wheel contact
surface clean affect the safe operation of the
trolley.
12 Safe Transportation
If you wish to transport your Elephant Lifting Products
trolleys to another site or for inspection, please observe
the following points:
1. Dismounting:
a) Make sure there is no load attached to the
trolley;
b) Attach the trolley load hook or suspension
plate to the chain hoist or other means of
lifting;
c) Remove beam or rail stops and slide the
trolley over the edge of the beam;
d) Set the entire trolley down carefully, do not
allow it to drop.
2. Disassembly:
a) Remove the crosshead from the side plates;
Note: Only necessary for geared trolleys.
b) Remove the chain from the hand wheel;
c) Remove the hand wheel assembly from the
geared side plate assembly.

8 | Page
Disassembling a trolley from the beam by separating the
slide plate is extremely dangerous and this operation
should be carried out by the trained or competent
personnel contemplated in SANS1824:2003 and
American Society of Mechanical Engineers (ASME)
standard B30.17-2015.
13 Storage
Store the trolley in a clean, dry place indoors. If lengthy
storage is required, lubricate wheels and place entire
unit in a suitable storage container. Store the product
away from heat and steam. Never allow it to rest for
lengthy periods of time on concrete or ash floors as the
lime sulfur and ash can cause corrosion.
14 Inspection
All inspections shall be performed by designated
personnel in accordance with the Elephant
Lifting Products recommendations and with the
requirements of ASME B30 Volume.
Any deficiency revealed through inspection must be
reported to an appointed or qualified person. A
determination must be made as to whether a more
detailed inspection is required or a deficiency constitutes
a safety hazard to continued operation. Such deficiency
shall be corrected before resuming operation of the
trolley. The results of the inspection must be recorded in
the inspection log.
Careful inspection on a regular basis will reveal potentially
dangerous conditions or evidence of malfunction while
still in the preliminary stages, allowing corrective actions
to be taken before the condition becomes dangerous.
Elephant Lifting Products recommends two types of
inspection:
a) The frequent inspection performed by the operator as
pre-work inspection.
b) The periodic inspections performed by personnel
trained in the operation and repair of these trolleys.
14.1 Frequent Inspection
Trolleys that are in continuous service, inspection should
be made at the beginning of each shift or before the trolley
is first used during each shift.
Elephant Lifting Products trolleys shall be
inspected at intervals depending on severity of
usage, as follows:
NORMAL HEAVY SERVERE
Monthly Weakly to Monthly Daily to Weekly
The following items shall be inspected:
1. Operating mechanisms of the trolley and hand chain
drive wheel for proper operation and adjustment.
Operate the trolley so that it travels 1 metre (3 feet)
along the beam. Inspect for visual signs or abnormal
noises such as but not limited to, squeaking, grinding
and grating which could indicate a problem. Do not
operate the trolley until all problems have been fixed.
2. Inspect trolley load hooks if used in accordance with
ASME B30.10 - 2015 Standard.
Trolleys that have been idle for a period of 1 month or
more but less than 1 year shall be inspected in
accordance with frequent inspection before being placed
into service.
14.2 Periodic Inspection
Frequency of periodic inspection depends on the severity
of trolley usage, as follows:
NORMAL HEAVY SERVERE
Yearly Biannually Quarterly
•Please note the requirements of the Occupational
Health and Safety Act of South Africa (Act 85 of
1993), Driven Machinery (Regulation 18), Lifting
Machines and Lifting Tackle regarding the
examination and testing of lifting machines and lifting
tackle.
Disassembly may be required for HEAVY or SEVERE
usage. Keep accumulative written test records of dated
and signed periodic inspections to provide a basis for
continuing evaluation. Records should be kept available.
Inspection of all the items in “Frequent Inspection” must
be conducted and also the following items shall be
inspected:
1. Fasteners
Check cap screws, retainer rings, pins and nuts. Replace
if missing or damaged and tighten if loose.
2. All Components
Inspect for wear, damage, distortion, deformation and
cleanliness.
If external evidence indicates the need, disassemble.
Check gears, shafts, bearings, wheels, load sheaves and
side plates. Replace worn or damaged parts. Clean,
lubricate and reassemble.
3. Drive Chain Hand Wheel
Check for damage or excessive wear of chain drive
sprockets and excessive chain stretch or distortion.

irregular sounds or other evidence of jamming, wedging
or malfunctioning.
4. Supporting Structure.
Check the supporting structure for distortion, excessive
wear and continued ability to support the load.
5. Trolley
Check that the trolley wheels run and track the beam
properly and that the clearance between the beam and
trolley wheel flanges is 1 to 2 mm maximum per side.
Check that wheels, bearings shafts, gears or rollers are
not excessively worn, cracked or distorted and inspect the
side plates for opening due to bending. Do not operate
the trolley until any problems have been identified and
fixed.
6. Nameplate.
Check for presence and legibility. Replace if necessary.
Trolleys that has been idle for a period of 1 year or more
shall be inspected in accordance with periodic inspection
before being placed into service.
14.3 Records and Reports
An inspection record should be maintained for each
trolley, listing all points requiring periodic inspection. A
written report should be made monthly on the condition of
the critical parts (e.g. wheels, bearings, side plates and
hanger shaft) of each trolley. These reports should be
dated, signed by each person who performed the
inspection, and kept on file where they are readily
available to the authorized personnel.
15 Troubleshooting
This section provides the information necessary for
troubleshooting the Elephant Lifting Products
Trolleys. The troubleshooting guide provides a
general outline of problems which could be
experienced with normal use of the trolley. Table 1 lists
the symptom, the possible cause, and the possible
remedy for the trouble being experienced.
Table 1: Troubleshooting
16 Maintenance
General maintenance should be performed in accordance
with the requirements of ASME B30 Volume and the
conditions and practices of a particular workplace.
Elephant Lifting Products trolleys are extremely robust
and require little maintenance. They are suitable for
use in explosion-hazardous areas as well as in
areas with increased concentrations of soot and dust,
high humidity and at ambient temperatures of – 20° C
up to approx. + 70° C if they are not heated above
this level due to external influences. The thermal
endurance of chains and hooks is up to + 150° C.
In order for the trolleys to operate safely and reliably over
a period of many years, compliance with maintenance
and inspection intervals is of immense importance. If the
trolley is being operated in a harsh environment that leads
to accelerated wear, then the maintenance intervals
should be reduced.
•Never perform maintenance on the trolley while it is
supporting a load.
•After performing any maintenance on the trolley, test
trolley as described in the “Safe Operating
Instructions”, Section 7, before returning trolley to
service.

16.1 Cleaning and Care
If your Elephant Lifting Products trolley has to work in
dirty surroundings, remove coarse dirt from the trolley.
Trolley wheel bearings are sealed and require no
lubrication. If trolley wheel rotation is rough or noisy,
replace trolley wheel bearing.
Threaded components of Elephant Lifting Products
Trolleys are metric. Verify and match thread sizes
before assembly.
16.2 Spare Parts
If during repair work, the replacement of components is
necessary, only original Elephant Lifting Products
spare parts may be installed.
17 Hand Chain Adjustment or Replacement
•When cutting the weld side of a hand chain link,
do not cut or nick the opposite side. A damaged
link must be replaced to prevent premature
failure. A falling hand chain can injure personnel.
•Proper use, inspections and maintenance will
increase the life and usefulness of your Elephant
Lifting Products equipment. During assembly
lubricate gears, threaded areas of nuts, bolts,
caps crew and all machined threads with applicable
thread lubricants or antiseize compound to prevent
corrosion and allows for ease of disassembly of
components.
17.1 To Replace Hand Chain
1. Cut a length of chain twice the required hand chain
drop plus 30 cm (1 foot)
2. Run the new hand chain around the hand wheel,
making sure that it is seated correctly in the hand
wheel sprockets.
3. To create a “C” link, cut the welded side of the chain
link and bend it open to grip the exposed part of the
link.
4. Connect the hand chain ends with the “C” link(s),
make the total number of links even and bend the “C”
link(s) shut.
5. If replacing the hand chain, disconnect it at the “C”
link and carefully remove the hand chain.
6. Make sure the hand chain is not twisted. To untwist a
hand chain, open a “C” link and remove one chain
link.
17.2 To Adjust Chain Length
Add or remove a length of chain twice the desired
amount of chain adjustment.
