CMC AZTEK Instruction Manual

INSPECTION, POINTS TO VERIFY
Inspection
User safety depends on equipment integrity. Equipment should be thoroughly inspected
prior to being placed into service and before and after each use. Inspect the equipment
according to your department's policy for inspecting life safety equipment. In addition, CMC
recommends a detailed inspection by a competent person at least once every 12 months
depending on current regulations and conditions of use. Record the date, inspector name,
and inspection results in the equipment log as well as any other relevant information to track
the usage history.
Before and after each use, the user should:
• Confirm the device is functioning properly.
• Verify the presence and legibility of the product markings.
• Verify there is no excessive wear or indications of damage such as deformation, corrosion,
sharp edges, cracks, or burrs. Minor nicks or sharp spots may be smoothed with emery cloth
or similar.
Prolonged use with carabiners or other hardware can create dangerous wear and sharp edges
that will decrease the safety of the device when used with textiles.
• Check for the presence of dirt or foreign objects that can affect or prevent normal operation such
as grit, sand, rocks, and debris.
• Verify that the swivel top rotates normally and the swivel axle bolt has not loosened.
• Verify that the main axle bolt has not loosened.
• Verify smooth rotation of the sheaves and security of the main axle bolt.
• Verify rope cover is tight and the rope end is secure.
• Always check the quick release Prusik pin – it has small balls that must extend to lock it in place.
• Verify spring pins are present and in place.
During each use, the user should:
• Confirm all pieces of equipment in the system are correctly positioned with respect to each other.
• Monitor the condition of the device and its connections to other equipment in the system.
• Do not allow anything to interfere with the operation of the device or its components.
• Avoid placing the device and attached connectors against an edge or sharp corner.
• Reduce the risk of shock load by minimizing slack in the system.
• Ensure swivel axle bolt has not loosened.
Retirement
CMC does not specify an expiration date for hardware because the service life depends
greatly on how and where it is used. The type of use, intensity of use, and environment of use
are all factors in determining the serviceability of the equipment. A single exceptional event
can be cause for retirement after only one use, such as exposure to sharp edges, extreme
temperatures, chemicals, or harsh environments.
A device must be withdrawn from service when:
• It fails to pass inspection.
• Sheave or swivel does not rotate smoothly.
• It fails to function properly.
• It has illegible product markings.
• It shows signs of damage or excessive wear.
• It has been subjected to shock loads, falls, or abnormal use.
• It has been exposed to harsh chemical reagents or extreme environments.
• It has an unknown usage history.
• You have any doubt as to its condition or reliability.
• When it becomes obsolete due to changes in legislation, standards, technique, or incompatibility
with other equipment.
Withdrawn equipment shall not be used again until confirmed in writing by a competent
person that it is acceptable to do so. If the product shall be retired, remove it from service and
mark it accordingly or destroy it to prevent further use.
PRODUCT USE
All pulleys are designed to specific performance criteria. Be aware of load limitations, manner
used, and proper technique. Do not overload a pulley. Pulleys can fail under improper use
conditions such as loading with a side plate open or applying a bending, shear, or torsional
load to the pulley. If you are not sure of proper application or technique, seek proper training in
pulley use and technical rope work. See below for additional product-specific guidance.
AZTEK pulleys are designed to be used in pairs in a pre-rigged mechanical advantage system
using 8mm cord. The end of the cord can be secured around the "horn" of one of the pulleys
and secured with the supplied end cap. A prusik hitch can be used for progress capture and
can be secured directly to the pulley via the plunger pin. Both the horn and the plunger pin
have a minimum breaking strength of 12 kN. The AZTEK pulleys can be rigged in either a 5:1
or a 4:1 mechanical advantage configuration. At any given time only one prusik hitch is used.
When not in use the prusik cord should be loosened and allowed to float on the cord.
Examples of Use:
(A) Prusik on Bottom Pulley: The bottom Prusik is active and the top Prusik is not attached.
Prusiks are color-coded to indicate which pulley they are used with (tactical black gear is
lettered). Do not use a Prusik with the mismatched color pulley. When the Prusik is holding
the load, only 3 sides of the rope are sharing the load and therefore the Prusik is holding
33% of the load.
(B) Prusik on Bottom Pulley - opposite side: This is the same setup as illustration (A) viewed
from the opposite side. The bottom Prusik is pinned to the bottom pulley. NOTE: Extra pins are
available to keep as a spare, but don't pin both Prusiks at the same time or you will be stuck.
(C) Prusik on Top Pulley: The top Prusik is pinned and the bottom Prusik is not attached.
When the Prusik is holding the load, 4 sides of the rope are sharing the load and therefore the
Prusik is holding 25% of the load.
Warnings
• When using a prusik hitch in conjunction with a pulley, care must be taken to prevent the prusik
knot from being pulled in between the side plates of the pulley. Prusiks must be properly tended.
• Make sure the quick release prusik pin is locked in place. Verify the small balls extend. Insert the
pin fully and then make sure it won't pull out.
• Do not use a double sheave pulley with only one sheave loaded.
• To prevent roll-out, use only locking carabiners. Do not allow ropes or objects to rub or twist the
sleeve because this could unlock it. Vibration can also unlock a sleeve. Sleeves must be locked
to achieve full strength.
• Check that the sheave is in good condition and freely rotates. Confirm security of the main
axle bolt.
• Do not let an object in between the sideplates and never rig your system so that the pulley is
forced against something that could break or open the sideplate.
• Verify that the swivel top rotates normally, and the swivel axle bolt has not loosened.
• Verify spring pin or set screws are in place and have not been removed. Confirm swivel top does
not move up or down.
• Pulleys must be free to align with the load. Any restraint is dangerous. Do not allow any bending
force on the pulley or it may break or break the connectors.
• Keep snagging hazards away from device. Beware that rope traveling through this device can
draw in hair, fingers, clothing, etc., causing injury and jamming the device.
• Moisture, ice, salt, sand, snow, chemicals, and other factors can prevent proper operation or
can greatly accelerate wear.
• Swivels are for orientation only. Not for high speed or multi-rotations. Verify swivel is rotating
freely.
• Do not use with wire rope or steel cable.
• Slack must be kept out of the system to prevent high impact falls.
• Use in Fall Arrest Systems
• The anchor point for the system should preferably be located above the user's position and
should meet the requirements of the EN 795 standard (12kN minimum strength).
• In a fall arrest system, it is essential to check the required clearance below the user before each
use, to avoid hitting the ground or an obstacle in the event of a fall.
• Make sure that the anchor point is correctly positioned to limit the risk and the length of a fall.
• A full body harness is the only device allowable for supporting the body in a fall arrest system.
MAINTENANCE AND CARE
Carrying, Storage and Transport
During all use, carrying, storage and transport, protect the equipment from sharp edges,
flame, extreme temperatures, rust, strong chemicals, and mechanical damage. Clean equip-
ment using clean fresh water to remove any dust or debris. Do not use a pressure washer
for cleaning. If the equipment gets wet, remove excess moisture with a non-abrasive cloth
and allow to air dry at temperatures between 10° C and 30° C. Do not use an automatic dyer,
tumble dyer, or direct heat. During storage and transport, protect the equipment from heat,
direct sunlight, moisture, chemicals, oils, and external loads or impacts. Do not store where
the equipment may be exposed to moist air.
