SECTION A – INTRODUCTION
5 Safety Overview
There is no one single factor that is more important for minimizing the possibility of personal injury to the
operator and those working in the area, or damage to property, equipment, or material than being familiar with
the equipment and using Safe Operating Practices.
MULE is designed for lifting and transporting of material only. Under no circumstances, either during initial
installation or in any other use, should the hoist be used for lifting or transporting personnel.
No operator should be permitted to use the equipment that is not familiar with its operation, is not physically or
mentally fit, or has not been schooled in safe operating practices. The misuse of MULE can lead to certain
hazards which cannot be protected against by mechanical means; hazards which can only be avoided by the
exercise of intelligence, care, and common sense.
Safe Operating Practices also involve a program of periodic inspection and preventative maintenance (covered
in a separate section). Part of the operator’s training should be an awareness of potential
malfunctions/hazards requiring adjustments or repairs, and bringing these to the attention of supervision for
corrective action.
Supervision and management also have an important role to play in any safety program by ensuring that a
maintenance schedule is adhered to, and that the equipment provided for the operators is suitable for the job
intended without violation of one or more of the rules covering safe operating practices and good common
sense.
Do’s and Don’ts (Safe Operation of MULE)
The following are Do’s and Don’ts for safe operation of MULE. A few minutes spent reading these rules can
make an operator aware of dangerous practices to avoid and precautions to take for their own safety and the
safety of others. Frequent examinations and periodic inspections of the equipment as well as a conscientious
observance of safety rules may save lives as well as time and money.
DON’TS:
•Never lift or transport a load until all personnel are clear and do not transport the load over personnel.
•Do not allow any unqualified personnel to operate hoist.
•Never pick up a load beyond the capacity rating appearing on the MULE. Overloading can be caused by
jerking as well as by static overload.
•Never carry personnel on the gripper, the hook or the load.
•Do not operate MULE if you are not physically fit.
•Do not operate MULE to extreme limits of travel of cable without first checking for proper limit switch
action.
•Do not tamper with or adjust any parts of the MULE unless specifically authorized to do so.
•Never use the wire rope as a sling.
•Do not divert attention from load while operating hoist.
•Never leave a suspended load unattended.
•Never operate a MULE that has an inherent or suspected mechanical or electrical defect.
•Do not jog controls unnecessarily.
•Do not operate MULE if cable is twisted, kinked, or damaged.
•Do not remove or obscure label.
DO’s:
•Read and follow manufacturer’s instruction, installation, and maintenance manuals. When repairing or
maintaining a MULE, use only manufacturer’s recommended parts and materials.
•Read and follow all instruction and warning information on or attached to the MULE.
•Remove the MULE from service and thoroughly inspect and repair, as necessary, if unusual
performance or visual defects (such as peculiar noise, jerky operations, travel in improper direction, or
obviously damaged parts) are noticed.
•Establish a regular schedule of inspection and maintain records for all MULEs with special attention
given to hooks, grippers, wire rope, brakes, and limit switches.
•Check operation of brakes for excessive drift.
•Never lift loads over people, etc.
1. All operators should read the Operators Manual before operating the Unit
2. Check the wire rope for improper seating, twisting, kinking, wear, or defects before
operating.
3. The installation and operation of MULE is subject to hazards that can be avoided only
by using extreme care and common sense. It is essential that the competent person
be appropriately trained in the installation, dismantlement, proper use and safe
operation of the work area jib hoist and its accessories.

Page 3
SECTION A – INTRODUCTION
•Check for damaged hooks, grippers and wire rope.
•Keep wire rope clean and well maintained.
•Check the wire rope for improper seating, twisting, kinking, wear, or other defects before operating the
MULE.
•Make sure a load clears neighboring stockpiles, machinery, or other obstructions when raising, lowering,
or traveling the load.
•Avoid swinging of load or load gripper when traveling the MULE.
•Be sure the load attachment is properly seated in the saddle of the gripper or hook. Balance load
properly before handling. Avoid gripper tip loading.

2 Standard System Components
Component Names
Powerpack – Houses power management and
distribution devices, air compressor and Lifting
Cable actuator.
Primary Arm – 1st Boom element closest to the
mast. The Powerpack is attached to the Primary
Arm and rotates around the rotation mast.
Ground Base – The Ground Base is the platform
MULE is built on. It can be picked in all 4 directions
for easy transport. Its slim size allows for it to fit
through 36” openings while the incorporated
outriggers and jacks provide for a level and stable
footprint.
Controller– The main operational interface for
MULE where most of the functions are located. The
Controller attaches to the working end of the Wire
Rope.
Fork Tubes – The Fork Tubes is attached to the
bottom of the rotation mast and is used to pick,
transport, and lift MULE. Cross pockets allow the
Fork Tubes to be picked from all four sides. System
can rest on level ground on the Fork Tubes. The Fork
Tubes can be disconnected to decrease weight or
remove obstacle
Grippers – The gripper or hook type device attaches
to the Handle through a U-Joint connection. Different
grippers allow for grabbing of different materials and
the incorporated U-Joint allow for the tilt of the load
to be precisely controlled during placement.
Secondary Arm – 2nd Boom element. Rotates around
the end of the Primary Arm. Data coil cord, coil airline
and Wire Rope come down from the end of the
Secondary Arm.

SECTION B – SYSTEM SUMMARY
Fork Tubes Adapter Plate
Allows Mast Sections to be directly mounted to the
Fork Tubes. Without special engineering approval,
this is only for use with Strap-over style MCWP
mounts.
Weight of adapter plate: 75 lb
One-Button Handle
This handle has a GRIP button built in for easy
access when the Gripper is unloaded.
Two-Button Handle
This handle has the GRIP and SET buttons built in
for easy access when the Gripper is unloaded.
This allows for a typical place cycle to be done
without releasing the handle.
Cord Reel
As an upgrade to the standard power cord, a
retracting cord reel can be installed to easily
dispense the right length of cord at the jobsite.
CMU Gripper 1” - 2 1/4” W/Button
Mount
The CMU Gripper 1” - 2 1/4” W/Button Mount is
the first of many grippers available for MULE.
This gripper is capable of picking CMU with
center webs between 1” and 2-1/4” thick. The
profile is minimized to avoid rebar interference.
An articulating arm holds the GRIP and SET
buttons to allow for easy access to the buttons
while holding the block. The user adjusts the
position of the button box for personal comfort
based on the material being handled.
This gripper does not change the load capacity of
MULE.
Wire Rope Extensions
Wire Rope Extensions allow for vertically moving
the 11’ working zone further from MULE. They
attach to the Wire Rope and coil cords the same
way that the Controller does. The Controller is
then attached to the extensions. Multiple
extensions can be hooked together for long
reaches.
The extensions will decrease the allowable load
by the weight of the extension.

5 Safety Features
Rotation Lock
When power is removed from MULE, a pin is engaged to lock the rotation of the Primary Arm. This is
primarily used in 2 situations; when building/dismantling MULE and moving MULE.
When MULE is being transported between sites, there is a pin that can be inserted to prevent the lock
from coming disengaged.
Preventing the Load from Dropping
When MULE is placing a load utilizing the GRIP button, it will not release the block until it senses that
the load weight is being carried by something else. This prevents a load from dropping unexpectedly
when the GRIP button is accidentally triggered.
Loss of Air
If air pressure is lost for any reason MULE is still in a safe condition. When air pressure is lost, the
Primary Arm Rotation Lock will engage keeping the arm and any possible load from drifting away. Also
the design of the Grippers prevents loads from being dropped by requiring air pressure to release. If air
is not available, the unit will no longer operate but will be in a safe condition.

Page 10
SECTION B – SYSTEM SUMMARY
Overload Protection
The software running MULE is constantly monitoring the load on the Wire Rope. If the capacity of 135lb is
exceeded the software will only allow for the controller to be lowered at a slow speed. This feature
prevents heavy loads from being lifted and possibly damaging the unit or risking a tip-over. Repeated
overload will cause premature failure of components.
6 Basic Requirements
Power: 20A@120V AC, 60Hz
Load to be placed: 10-135 lb
7 Your Machine
As each MULE is made up of several main components, there are multiple serial numbers on each
machine to allow for product tracking. For your records it is smart to record these numbers upon receipt.
Serial Number Stickers can be found in the following locations:

•Mast height not to exceed 41 ft
If the desired setup exceeds any of the requirements above or other limits described throughout this
manual, contact Construction Robotics with specific details for non-standard engineering approval.
Additional engineering charges may apply.
If any uncertainties with the contents of this manual arise or clarifications are required, contact your
Dealer immediately.
2 Powering MULE
MULE requires clean, steady power to run. When running off a standard wall outlet with no extension
cord, no issues should be encountered during standard operation.
If a generator or extension cord is being used, be sure to follow the guidelines in the sections below to
ensure smooth operation of MULE.
Power Requirements
Voltage: 120V (+/- 6V) (if voltage is out of range, see section G6.1 on page 39 to adjust MULE)
Amperage: 20A (at full speed and full capacity)
Frequency: 60 Hz
OSHA requires that MULE be powered through a GFCI receptacle when using temporary site power or
generators over 5000W (1926.404).
Be sure to follow all OSHA procedures for all power connections.
Generator Power
When site conditions require the use of a generator, it is important to have capable equipment
available.
Many standard jobsite generators with less than 4000 Starting Watts do not have the power to handle
the peak loads of MULE without creating power conditions that will cause faults. The newer inverter
style generators provide cleaner power than standard generators.
When using a generator CR recommends using Honda EB2800i with Eco mode turned off.
Using Additional Extension Cords
MULE comes standard with 50’ of power cord. Whenever possible, it is best to bring the power source
into the range of MULE’s power cord.
If it is necessary to add an extension cord, refer to the chart below for the proper gauge based on the
length that is needed. Use of a smaller gauge cord than specified may lead to errors that prevent
machine function.

3 Setup Process
Base Distance from Wall
The distance MULE sits from the wall face determines how many lineal feet of wall can be worked in a
single setup.
In some cases, MULE must be set further back than desired due to site obstacles. No problems will be
encountered if the area in Figure C-1 is clear.
For a straight wall follow the table below:

SECTION C – SYSTEM SETUP
Outrigger Position
Before assembling MULE the outriggers within the
Ground Base have to be extended and locked into
position. These allow MULE to be stable while
making the Ground Base able to fit through a 36”
opening.
To extend the outriggers, pull the center pin out
completely, this will allow both outriggers on one
end of the Ground Base to slide freely.
Once the outrigger is free to move, slide it out until
the line on the outrigger is lined up with the edge of
the Ground Base. Be sure that the correct side of
the outrigger is facing up.
Once the outrigger is extended to the correct
position slide the center pin back in to lock them in
place.
This procedure needs to be done on both ends of
the Ground Base for all 4 outriggers.
Install the jacks in the outriggers, with the handle
pointing up.
Base Leveling
The maximum capacity of the Ground Base is 3700
lb. Do not exceed this capacity; use the weights
above in the document to determine how much
non-MULE weight can be supported at any time.
Ensure the ground or bearing surface under the
jacks has the necessary capacity to support the
total load. Follow the table below based on system
weight for bearing surface requirements:
Cribbing may be needed under each jack foot to
increase the bearing surface capacity.
Using a 2’ or 4’ level, level the base in both
directions using the jacks.
Ensure that the jacks are not extended more than
22” below the bottom of the outrigger. See Figure
C-2
To fully extend the jacks, a pin adjustment is
required. Remove the pin shown in Figure C-3,
extend the jack by 1 position and insert the pin. It
is not permitted to extend the jack past the 2nd
position.
When leveling is complete, check that all 4 jacks
are contacting the ground and carrying weight.
Using Wire Rope Extensions
When work is required below the standard cable
reach extensions to the Wire Rope are required.
They connect to the Wire Rope and coil cords as
the controller does. The controller then connects
to the extension. Multiple extensions may be
hooked together for tall setups.
Controller Installation
Attach the Controller to the Wire Rope loop using
the clevis pin at the top. Secure the clevis pin with
the lock pin.

Wheel Set Assembly – Optional
Accessory
For MULE to be assembled to the Wheel Set, the
mast must be no taller than:
•CR Mast: 6 ft (11ft with specific approval from
CR Engineering)
•HM Mast: 1 Section (6 ft with adapters) (11ft
with specific approval from CR Engineering)
•The Wheel Set is attached to the Ground Base
using (4) plow bolts provided with the Wheel
Set.
To lift the Ground Base, move the pin in the jacks
to the 2nd position and crank the jacks evenly to
lift the pallet high enough to allow the Wheel Set
to roll under, never exceed 3° of tilt (on both
inclinometers) during this process.
Once the Wheel Set is under the Ground Base,
align the 4 holes in the Wheel Set with the holes in
the bottom of the Ground Base. Insert provided
plow bolts and install washer, lock washer and
nut on the bottom of the Wheel Set. Tighten with
provided wrench to 80 ft-lbs. Once the bolts have
been tightened the jacks can be let down so that
the assembly can roll.
The Wheel Set has a maximum capacity of 3200
lb. Do not exceed this capacity; use the weights
above in the document to determine how much
non-MULE weight can be carried at any time. The
Wheel Set has enough capacity to support MULE
in the standard configuration. If using the Flat and
Smooth case (Section C4.2(b) on Page 16),
capacity may be an issue and weight must be
calculated.
When using MULE, no wheels may be touching
the ground, they should be able to spin freely;
ensure that all 4 jacks are contacting the ground
and have similar amounts of weight on them.
When in operation on the jacks, Section C3.3
must be followed.
