I was wondering if anyone can advise me as to the noise emissions from a Scissor Lift - something general will suffice, the Main Contractor has requested this information. I cant really see it of being any consequence..!!

Ronan,
There's nothing you can do except measure the noise level coming from it. Get yourself a noise meter, make sure it's calibrated and taike the readings. Irish legislation now has three levels; 80, 85 & 87 dBA.
Having said all that I think your main contractor is going over the top when asking for this. I've never come accross this before and perhaps someone else on here might enlighten me onwhy is should be required.
The simplest answer might be to give your drivers/operators hearing protective PPE to solve the problem or provide an earplug station (quite inexpensive) in the area where you have your scissor lift.

Some scissor lifts do have powered rollers/castors that can generate an appreciable amount of noise when in use, but I wouldn't have thought the raising and lowering of the lift would be a noise issue.

Hello Ronan,
Personally, I have never come across a Mobile Elevating Work Platform that generates sufficient and persistant noise levels to cause me any real concern.
In fact, my immediate reaction to such high or excessive noise levels would be to suspect it as being generally unusual and possibly faulty. In such a case I would pervent the equipment being used as a precaution and take the necessary action.
This means sourcing a suitably quieter machine. I do not think that the solution would be to issue the operator with hearing protection for obvious reasons.

I don't know the technical term but "scissor lifts" have a lattice arrangement which,when closing, lifts the platform vertically. Try google or wiki. Most, not all, are electric powered by batteries with a noise level of around 80 dBa. Diesel powered ones can go somewhat higher but those I have met have been well muffled.
Your client may be worried about additioning of noise sources. If they have an area of less than 80 then adding your 80 could take them over the top locally. 80+80 can add up to 83.

Don't forget while in operation for manouvering reversing, audible warning devices are used they tend to be over 100dBA while being used inside buildings for prolonged periods it can get a litte anoying. Invaluable for safety.
Merv is correct electrical lifts are no more noisy than an electric FLT.
Diesel powered are bound to be more noisy, but hey who ever heard of a quiet building site!
Manufacturers should be supplying figures for noise emissions check operators handbook etc.
Regards Alan.

The noise from a 500RTS Scissor lift at the base is about 107decibels and 84 decibels at about 6metres high.
Solution if somebody is working at the base turn off the machine.
If they are working in the machine at base level precautions required.
go electric if possible?
