Ingersoll Rand EZTT080 Manual De Operación Y Mantenimiento página 7

The four most important aspects of operation are:
1. Follow all safety instructions when operating the unit.
2. Only allow people trained in safety and operation of this product to
operate the unit.
3. Subject each unit to a regular inspection and maintenance program.
4. Be aware of the unit capacity at all times.
Ensure operators use suitable personnel protective equipment when
operating EZ-Torque Tubes and attached tools. Maintain personnel
protective equipment in accordance with manufacturers instructions.
At the end of each shift, or prior to turning off air supply, lower tool to its
lowest position.
Description Of Operation
The EZ-Torque Tube is an integrated group of components designed to
maximize the interaction of man and machine. Ease of operation
minimizes operator fatigue and incorporates added safety during the
performance of repetitive tasks.
Principles Of Operation
The EZ-Torque Tube is designed to allow vertical operational control
within a specific range of motion.
• All new, altered or repaired equipment should be inspected and
tested by personnel instructed in safety, operation and maintenance
of this equipment to ensure safe operation at rated specifications
before placing equipment is service.
• Never use a unit that inspection indicates is damaged.
The inspection intervals recommended in this manual are based on
intermittent operation of the equipment eight hours each day, five days per
week, in an environment relatively free of dust, moisture and corrosive
fumes. If the equipment is operated almost continuously, or more than
eight hours each day, more frequent inspections will be required.
Frequent and periodic inspections should be performed on equipment in
regular service. Frequent inspections are visual examinations performed
by operators or personnel trained in safety and operation of this equipment
and include observations made during routine equipment operation.
Periodic inspections are thorough inspections conducted by personnel
trained in the safety, operation and maintenance of this equipment.
Inspection intervals depend upon the nature of the critical components of
the equipment and the severity of usage.
Careful inspection on a regular basis will reveal potentially dangerous
conditions while still in the early stages, allowing corrective action to be
taken before the condition becomes dangerous.
Deficiencies revealed through inspection, or noted during operation, must
be reported to designated personnel instructed in safety, operation and
maintenance of this equipment. A determination as to whether a condition
constitutes a safety hazard must be made, and the correction of noted
safety hazards accomplished and documented by written report before
placing the equipment in service.
Records and Reports
Inspection records, listing all points requiring periodic inspection should
be maintained for all load bearing equipment. Written reports, based on
severity of service, should be made on the condition of critical parts as a
method of documenting periodic inspections. These reports should be
dated, signed by the person who performed the inspection, and kept on file
where they are readily available for authorized review.

OPERATION
When installed on a trolley-rail system, push on the external column or
tool to move in a horizontal direction. During travel ensure load travel
path is clear and pay attention to direction of travel during movement.
Vertical raising and lowering of the system should be easily accomplished
by exerting force on the attached tool. On air cylinder or spring balancer
equipped units, use tool to raise and lower Torque Tube.
Tool Holder (optional feature)
Two Tool Holder designs are available.
Fixed Horizontal/Vertical (Two Axis):
To reposition tool either loosen tool clamp capscrews to rotate tool in
holder, or loosen the four mounting capscrews to rotate complete tool
holder assembly. Tighten capscrews when correct adjustment is obtained.
360° Tool Holder (Three Axis):
To rotate a tool held in tool holder. pull out plunger and rotate to desired
position. Allow plunger to spring return to locked position. Rotate tool
slightly to engage locking pin.
Tool holder may also by rotated by loosening the four mounting
capscrews to rotate complete tool holder assembly. Tighten capscrews
when correct adjustment is obtained.
INSPECTION
For equipment in continuous service, frequent inspections should be made
by operators at the beginning of each shift.
1. OPERATION. Check for visual signs or abnormal movement which
could indicate a potential problem. Ensure tube and trolley
movements are smooth and unrestricted.
2. FASTENERS. Ensure fasteners are secure. Tighten loose and
replace damaged fasteners.
3. COLUMNS AND OPTIONAL TOOL EXTENSION. Check for
wear and damage. Repair or replace as necessary.
4. SIDE PLATES. Check for wear or damage. Replace if worn or
damaged.
5. SAFETY CABLE. Check clamps are secure. Tighten clamps if
necessary.
6. AIR SYSTEM. Visually inspect all connections, fittings, hoses and
components for indication of air leaks. Repair any leaks or damage,
tighten any loose connections.
Frequency of periodic inspection depends on the severity of usage:
NORMAL
yearly
Disassembly may be required for HEAVY or SEVERE usage. Keep
cumulative written records of periodic inspections to provide a basis for
continuing evaluation.
Inspect all the items in "Frequent Inspection". Also inspect the following:
1. FASTENERS. Verify fasteners are tight. Torque fasteners to
recommended torque levels.
2. SIDE PLATES. Replace the side plates once per year regardless of
condition. Refer to "PARTS SECTION" for replacement part
numbers, and "MAINTENANCE" section for replacement
instructions.
3. SPRING BALANCER. Inspect spring balancer in accordance with
manufacturers literature.
4. AIR CYLINDER. Check cylinder vent is clean and unrestricted.
Check cylinder for leaks and external damage. Replace or repair
cylinder as required.
5. TOOL HOLDER. Check tool holder rotates freely and locking
mechanism provides positive stop. Check tool holder clamps are not
damaged.
