Arctostaphylos uva-ursi

What sort of money is the D30?

Surely a crown lift would suffice in that case?

Don't really think it is a tree that lends itself to crown reduction. I have only ever deadwooded them as they seem to keep themselves pretty trim otherwise.

Horse chestnut is fine in a stove but can spit on an open fire. It will obviously need to be stacked in a dry place for a year before you can burn it. Split the larger wood now as it will help it dry out.

No it is definitely a Horse chestnut. Find yourself a professional crew.

er? No

To the height of the trellis! That is not pollarding its topping. The trees would become an eyesore in my opinion and you will be locked into a cycle of continual management of any regrowth and rot.

Fair do's

I don't care which method you choose just don't damage that lovely concrete meerkat and mole ensemble in the birdbath.

Gosh David! All those limbs bar one have blown off that tree in the third picture!!

Nice video. Puzzled as to why you chose to rig some of the top sections and not others? Were they rigged just to keep the ground crew occupied and warm?

It's a good clear video. I am just not overly enamored with the device.

Just so. WLL is the working load limit which is the maximum load which an accessory can by design lift. SWL safe working load is the load that can be lifted under particular service conditions. e.g. The SWL of sling chains depends on the included angle.

Interesting device. The brake looks to be a bit of an unnecessary faff to me as it is not mid-line detachable so you have to feed the entire rope though to employ it. I am not sure that the bolts in the aluminium frame would be stronger than the full length welds on the GRCS. You suggest rust might be a problem but I have no such issue with mine. I assume that the bolts are steel? Have you ever noticed the corrosion that occurs between steel and aluminium over time? (Take a look at an old landrover!).

WLL and SWL are abbreviated terms commonly used in the field of engineering. “WLL” stands for “working load limit” while “SWL” stands for “safe working load.” The main differences between safe working load from working load limit is that “SWL” is the older term. Today, SWL is not used anymore because it has been completely replaced by the term WLL. Let us discover the reasons why engineers put an end to using the term “safe working load.” “Safe working load” is also synonymous with “normal working load.” According to irata.org, “safe working load” is defined as “the breaking load of a component divided by an appropriate factor of safety giving a safe load that could be lifted or carried.” Safe working load is the amount of weight (load) that a lifting device can carry without fear of breaking. Now, who sets the load capacity for certain lifting equipment? It is the lifting equipment’s manufacturer. The manufacturer recommends the maximum load capacity of his lifting equipment. The lifting equipment or device can be a rope, a line, a crane, hooks, shackles, slings, or any lifting device. To know the safe working load, the lifting equipment’s minimum breaking strength is divided with the safety factor that is constant or assigned to a particular type of equipment. Usually, the safety factor of a particular equipment ranges from 4 to 6. If the equipment poses a risk to a person’s life, the safety factor is raised to 10. Since the definition of “safe working load” is not very specific and there are legal implications, the USA standards began to stop using this term. A few years after the USA standards began to stop using this term, the European and ISO standards began to follow suit. Later on, both the Americans and Europeans developed a more appropriate term and definition for the maximum load capacity of a particular lifting device. Both parties agreed to the use of the term “working load limit” or WLL. Based again on the pdf file presented in itera.org, the specific definition for the working load limit is that it is the maximum mass or force which a product is authorized to support in general service when the pull is applied in-line, unless noted otherwise, with respect to the centerline of the product. This definition can also be added to refer to the following definitions: the maximum load that an item can lift; and the maximum load that an item can lift in a particular configuration or application. The working load limit of a lifting equipment depends greatly on a competent and skilled manufacturer who can wisely designate its WLL value. It’s the responsibility of the manufacturer to determine the right or approximate WLL value for each lifting device. To come up with a WLL value, there are many factors to consider. This includes the speed of operation, the applied load, the length of each rope or line, size, number, and etc. Any factor that can affect the working load limit of a lifting device should be carefully observed. Summary: WLL stands for working load limit while SWL stands for safe working load. WLL and SWL are terms often used in the field of engineering. Safe working load is the older term of working load limit. The definition for safe working load is the breaking load of a component divided by an appropriate factor of safety giving a safe load that could be lifted or be carried. The working load limit is that it is the maximum mass or force which a product is authorized to support in general service when the pull is applied in-line, unless noted otherwise, with respect to the centerline of the product.

I always favour the Isaac Newton too, but when things are likely to get broken or damaged I call on the services of Mr Good (the original and best in my humble opinion).

Nice idea. Trouble is people will want to keep jumping on it!

Where did you get it broadsword?

Interesting! Thanks for coming back. Great video.

Possibly Norway maple?

Here's the new one:

Sloppy

What works have been prescribed? Can you post some "after" pictures too?

That was my next best guess!
