Ingersoll-Rand QCH Series, Product Information

Page: 5 / 12

OPERATIONAL PARAMETERS
Quantum Electric Hoists are intended for general industrial material handling
operation with freely suspended loads. The electric chain hoists of the QCH Series
are capable of different load capacities. They can be installed as stationary or mobile
units. Electric chain hoists are manufactured in accordance with the latest technical
developments along with the latest technical safety regulations and specifications,
and are tested for safety by the manufacturer. The operational parameters of the
electric chain hoist also encompass the compliance of the safe operating practices,
maintenance information and parts information manuals.
The operational parameters do not include:
• Exceeding the defined load capacity,
• Diagonal pulling of the load or yarding,
• Excessive impact or lifting of guided loads.
Excessive inching operations, ground mooring and running against limit switches,
should be avoided.
Operating temperature is –20° C to 50° C (68 ° F to 122 ° F)
Hoists are rated at H3 Duty Class in accordance with ASME HST–1–1999.
The manufacturer accepts no responsibility for any damage to this equipment,
resulting from abnormal operating practices.
START-UP
DANGER
• Mechanical adjustments should be performed by authorized designated
personnel.
CAUTION
• The operating staff must carefully read the operating instructions of the
electric chain hoists before its initial operation and carry out all checks. Only
when a safe operation has been established may the device be put into
operation. Unauthorized persons may not operate the device or perform
any work with the help of the same.
n
Transport and Assembly
For the transport and assembly of the electric chain hoists, the safety direction for
handling with loads are to be followed. Refer to Product Safety Information Manual.
The electric chain hoists must be assembled by qualified staff, always bearing in
mind the accident prevention directions. Before assembly the electric chain hoist
must be stored in an enclosed room or covered area. Should the electric chain hoist
be destined for operation outdoors, then it is recommended that a protection roof
is erected to shield it from the influences of the weather.
Whenever possible, the electric chain hoist should be transported in its original
packaging. It is recommended that the assembly and connection of the electric chain
hoist is effected on-site by qualified designated personnel.
INSTALLATION
Prior to installing the hoist, carefully inspect components for possible shipping
damage.
Hoists are supplied fully lubricated from the factory. Refer to “LUBRICATION” section
for recommended oils and lubrication intervals. Lubrication of the load chain is
recommended before initial hoist operation.
WARNING
• A falling load can cause injury or death. Before installing, read Product
Safety Information Manual.
• Owners and users are advised to examine specific, local or other
regulations, including American National Standards Institute and/or OSHA
Regulations which may apply to a particular type of use of this product
before installing or putting hoist to use.
n
Mounting
Make certain your hoist is properly installed. A little extra time and effort in doing so
can contribute a lot toward preventing accidents and help you get the best service
possible.
Always make certain the supporting member from which the hoist is suspended is
strong enough to support the weight of the hoist plus the weight of the maximum
rated load plus a generous factor (consult a structural engineer).
If the hoist is suspended by a top hook, the supporting member should rest
completely within the saddle of the hook and be centered directly above the hook
shank. Do not use a supporting member that tilts the hoist.
n
Hook Mounted Hoist
Place hook over mounting structure. Make sure hook latch is engaged.
n
Trolley Mounted Hoist
When installing a trolley on a beam, measure beam flange and temporarily install
trolley on hoist to determine the exact distribution and arrangement of the spacers.
Adjust spacers in accordance with trolley manufacturer’s literature to provide the
correct distance between the wheel flange and the beam. The number of spacers
between the trolley side plate and mounting lug on hoist must be the same in all
four locations in order to keep the hoist centered under the I-beam. The remaining
spacers must be equally distributed on the outside of the side plates.
WARNING
• At least one mounting spacer must be used between the head of each trolley
bracket bolt and the trolley bracket and between each trolley bolt nut and
the trolley bracket. Failure to do this could cause the hoist to fall when used
improperly.
Ensure trolley bolts or nuts are torqued in accordance with manufacturer’s
specifications. For installation of hoist and trolley on beam, make certain the side
plates are parallel and vertical.
After installation ensure beam stops are in place, operate trolley over entire length
of beam with a capacity load suspended 4 to 6 inches (10 to 15 cms) off the floor.
CAUTION
• To avoid an unbalanced load which may damage the trolley, the hoist must
be centered under the trolley.
NOTICE
• Trolley wheels ride on the top of the lower flange of the beam.
n
Power Connection
DANGER
• Electro technical adjustments should only be performed by authorized
specialists.
The main connection cable, fuse and the switch must be installed by the customer
before connecting the electric chain hoist to the mains power supply.
A 4-wire cable with a ground protective conductor is needed to provide the power
supply for three-phase models. A 3-wire cable with a protective conductor is
adequate for single-phase models. The length and the gage must be determined to
support the power consumption of the electric chain hoist.
DANGER
• The ground conductor must not carry any power. With motorized trolley
operation, the power supply is enclosed in a terminal box on the drive
motor. With the installation of a motor protector, the load plate voltage of
the electric chain hoist must be noted.
CAUTION
• Checking direction of rotation: If the direction of rotation does not
correspond with the button symbols on the control switch, power supply
wires L1 and L2 must be swapped around.
NOTICE
• Make sure wire connection at the terminal is in accordance with Dwg.
MHP3318.
Electrical Connections if not tight and secure, will cause a fire. During installation
the electrician must make sure that all electrical connections including the ground
connection are secure. Make sure all junction boxes and switch enclosures are
adequately sealed and protected for the environmental conditions to be
encountered.
