Best left for the inevitable HSE investigation.

I think you would have to give a reason if a judge were asking. I only ask because I would love to refuse an applicant on the basis of smoking. I had on guy try to quit with the gum once. I don’t know what was worse, the smoke or the constant “cud chewing” noises.
-
Bu**er, I see where you are comming from Steve. Would the equal opps brigade allow you to refuse an applicant on the basis of smoking? That would be an interesting thread.

Back in the day I would have been the take it man but these days I am too old and married. It might not be a case of take it or leave it though. Can you legally stipulate what your employees can and can’t do in their own time? America is the “home of the brave and the land of the FREE”, and positive discrimination, not forgetting the no win no fee lawyer so I was wondering if you can make that condition stick.

I don’t like smoking either, but it wouldn’t make me think a contractor was unprofessional. I recon many smokers cant see further than their addiction and wouldn’t think it unprofessional either. I wouldn’t like it in my home but people smoking in the garden doesn’t bother me. Drug policies notwithstanding, how do you stand legally telling employees what they can or can’t do outside their hours of employment? UK or US

There are plenty of people in our industry who don’t like the requirement for qualification. Some regard it as an insult to their abilities or intelligence. I certainly wasn’t that impressed when I returned to the UK after 6 years to find I needed a suite of competences to carry on doing what I had already been practicing for a decade. Without passing comment on no win no fee lawyers, in a scenario like this the ability to demonstrate training and assessment would probably have made this case a non starter, or at least substantial reduced the culpability of the employer. From an employers point of view this is what qualifications are for. If they could demonstrate that claimant had been trained and assessed. Your insurers don’t ask for proof of competence for no reason. Andy

Ahhhhhh Me too Does this mean I am not a control freak after all?

Give me a chance, I have to wait till dark or the wife will see me sneaking out.:sneaky2::sneaky2:

Well if you flog the old rotator on eBay (pretend your junk is worth something). You could end up with a serviceable grapple for a bit more than scrap price.
-
For modern forestry, it’s a bit “antiquated” and non continuous rotation is a drawback. It will however do the arborists job and for £150.00 you can’t go wrong.

Or even That cacked me up mate

Why are you fuming? Did you not do something to deserve the points? I got 3 points for using my mobile this year. (having lost of broke yet another Bluetooth set that morning). You can only be philosophical about it. I was bang to rights doing something I knew I shouldn’t have been doing. I even started the call so I have no reason to be upset. I had a laugh with the traffic cops and told them (as I was leaving) that I hoped their next bowel movement was a porcupine. Andy

You are quite right, about the effort involved. Ed hit on it earlier in the thread with the size of the pump involved. High pressure hand pumps have a very low displacement and are easier to pump but are slower. A line in the tree is also mechanically far more efficient than jacking. It also has the advantage that you are pulling the tree onto the hinge rather than jacking it off the hinge. Out of interest I set an experiment with a 90 ton “enerpac” ram I managed to snap a quite substantial hinge on a lump of 30” diameter poplar. I decided the enerpac was a bit much for the job. I would like to think that stateside they use the jacks on much larger trees with bigger hinges. Andy

Sorry you think accuracy is pedantic but if you are offering advice it ought to be accurate. If you want pedantic it’s not a one way system, it’s called a single acting ram. Like I said 45tons is nice but I managed with a fraction of that at a fraction of the cost.
-
If you are the scrotes that nicked my winch of the front of my disco you get what you don’t pay for. If you fit one a couple of strategic welds are a good idea. Andy

Certification (ISA) is a purely theoretical qualification. Hard to see how that would give any tangible benefit to a new climber. Andy

The rod has nothing to do with the pushing force of a ram. It only affects the pulling force and the speed of the “inward” stroke. As I have said before the pushing force of a ram is a function of the bore (area) and the pressure. Yes you need a bigger ram but who says you need 45 tones? I can give you 145 tones in not much more size but do you need it? What matters is the surface area in relation to the force. Don’t forget that the Silvey jack is from the land of big redwoods. I managed some big orrible trees with a weedy 13 tonnes and if you design it right you don’t need to cut it into a stem. Andy

Fluid dynamics is going to have to differ with you on the tractor part. As I said the force the ram exerts is a function of pressure and area. Lower input pressure just means you need a bigger ram. I made a portable log splitter to carry on the chipper for busting up the odd bit of dross timber that was that bit too big to chip. I adapted it to double as a felling aid. It made better than 13 tons of force (granted it had a 4 inch ram bore) and I have shoved more scabby pops about with it that I care to remember. It ran from the chipper but any hydraulic supply would do. Only the flow would change (annulus speed). Clearly not suitable for every job but effective (and dirt cheap) nonetheless. I did have thoughts on using a spare enerpac ram and pump upping the force to 10,000psi and 90 tons but the one concern I had was shoving the stem up and off the hinge rather than over it. Andy

The generic name for it is a “socket weld coupling”. I play with hydraulics a lot and I haven’t bought one in a god’s age. They are however quire simple to make all you need is an end plug coupling with the appropriate thread in it and drill a socket hole to fit your pipe. Alternatively in the unlikely event that the solid pipe is in good order and not bashed to buggery you could use a compression fitting on it and weld the pipe to the ram further up via an appropriate spacer.

Its the specification I was given and we dont all work in the depths of the woods.
-
Depends on what you want to use it for. Occasional use and self recovery you will be fine with an electric but if you want endurance go with hydraulic.
-
That’s going to be a hell of a spring to push fluid back down 60 feet of hose. Better to use an air operated jack even if you have to run in from a weedy 12 volt tyre inflator. It would be slow but it would get you there.
-
The force a ram exerts is a function of the pressure and the dimensions of the bore. The compact rams you were using (Enerpac?) do operate at higher pressures but you can get 20 tons of force out of a regular ram. Most tractors make about 2200 psi, the only problem is that you would need a feed and return (Siamese) hose which is going to be cumbersome and heavy (full of oil) at any sort of length. Pressure drop would not be a significant issue. There are air operated hydraulic jacks that would only need an air feed, which is available on most commercial vehicles.

Before you spend money the engine check the charging circuit for continuity. It can be something as simple as a blown bulb. Andy

Should you need a licence to be an arborist?

I have come across more than a few climbers who think all they should do is climb. Andy
