somebody can send me all the information about the hyflex please,

thanks

Dennis,

You could fabricate a tool instead of the board. A battering ram like tool with a soft end cap to prevent damage to the pipe. Make your handles on the tube about 1.25" to 1.75" in diameter. I would design it to be used with the hands under and over (like you hold a rake) and maybe two handles at right angles. The two right angle handles would reduce the stess on the shoulders when the worker hits the upper height range of the pipes. The pictured worker's smaller shoulder muscles appear to be isolated. It is best if the worker can keep their hands around the waist or belly button when using the tool. Two handle choices should help. Make the tool light to prevent shoulder strain.

I see a problem with a hand banging against the open ended tubing and that would be a nasty cut. You would want the hands protected behind the BIG cap and you would have to build another deflective guard for the right angle handles.

Do you have a picture of your stamping process?

Hope this makes sense....

Pam,

Please send my what information you have on them. You have my e-mail already.

Thanks,

Dennis

As far as the code stamping process, they make engravers that work really well. I can give you some information if you need. I'm still thinking about the hammering issues.

I was thinking that you could fabricate a support that has a counter balanced impact hammer that would perform the same function. the hammer could run on a track (side to side) and the counter balancer could provide the vertical height variation you would need. The counter balancer would support the impact hammer to reduce shoulder strain and the impact hammer could potentially reduce the impact forces.

The company I work for we produce heat exchangers, pressure vessels, reactor towers, and such. In this process we also have a machine shop that conducts the machining for the baffles tube sheets, etc. At the machine shop plant there are several ergomonic questions that I have posed, but can't seem to find the asnwers to. One concern is when feeding the tubes into a skeloton the employee's somethins have to use a board to finish hammering them into place (see attached pics) the other issue is our code stamping process where our employee has to use a hammer and a stamp to code stamp the face or side of the baffle. any suggestions on ways to reduce or elminate the ergo potenial with either?

ERGONOMIC CONSIDERATIONS WHEN SAFEGUARDING MACHINES
When safeguarding a machine ergonomics consideration is as important to the health and safety of the employee as the technique for safeguarding its self. Worker stress and fatigue can be averted by well designed work stations, and well integrated guarding.
Consideration when designing modular or cellular workstations should be paid to the following.
Sources of vibration and noise. The location of the operators control panels,( note when safety distance is used as a primary control method this safe distance must be re-measured to assure that the users safety operation controls are at the correct distance.) Mechanical stressors, this may include any sharp edges or hard surfaces, and any worked undertaken in a static position for extended periods of time. Anatomical posture a workers back and upper extremities can become very tired over time if work demands awkward postures. Forceful exertions many tasks may require high and sometimes frequent manual force to complete the task. Repetition the rate at which equipment is used on tasks that must be performed per a unit of time, may be excessive for some workers and can be the cause of chronic fatigue or even injury. Temperatures extreme environmental temperatures can likely adversely affect a workers performance, sources may include high levels of background heat that may cause fatigue or cold air or surfaces that can reduce blood flow.
Note Special reference should be made to OSHA 1910.217 for safety distance calculations.

Good day to all, I look forward to interacting with the group and gaining some great info

Great to have this group. I haveing ergonomic project at my workplace about preparing ergonomic trainning package.
I have no idea what to do first!
