Rock grabs are a vital attachment for moving rocks and other large and heavy objects, but it can be difficult to figure out exactly which grab is the right one for you. Here are some things to think about when choosing your rock grab.
Use
The first thing you need to consider is what you will actually use the attachment for. If you already know the approximate size and weight of the rocks that you need to move around, you will already have a good idea of the type of rock grab you will need. You should also take into account the lifting capacity of the machine that you will be using. This information will already guide you towards the right choice for your task or towards a more general-purpose rock grab if you will need it for a number of different jobs.
Finger protection
You should choose a rock grab with hard steel protection around the fingers. Wear around the fingers will significantly affect the life of your rock grab. You will be working with rough and heavy materials that can easily damage unprotected fingers on the rock grab, so wear-protection is a must.
Material
The material that the rock grab is made from will have an enormous effect on its life. A rock grab can easily suffer from twisting, warping or even tearing in the face of heavy and solid materials, particularly if you use it for demolition work. You will want a grab made from high-quality steel - anything else may not be strong enough for the work you will be doing.
Static or hydraulic?
A hydraulic grab has numerous advantages over a static one - it has a full range of motion, can be much easier to attach and remove from your excavator, and the grabbing action will always be the same, regardless of the tilt. Against this, however, they are much more expensive than a static grab and will require more maintenance. If you are tempted to buy a hydraulic rock grab, you should consider very carefully whether the advantages will make a big enough difference to justify the extra cost and maintenance.
You should not buy the first rock grab you come across - or the cheapest. By carefully considering the work you will be doing and going for quality, you will ensure you buy a rock grab that will last for many years.

I was so happy when I finally escaped the city and built my new life on the farm. For many years, I had worked as a lawyer in the city of Perth. While the work was interesting, the hours were long and I hated being trapped in the big city. I remember how as a child, my father would take me out into the countryside. I decided I was going to quit my job and make a fresh start. I was so excited. However, I got a real shock when I arrived on the farm and I realised I didn't have a clue about farming. Thankfully, over the past 6 months, my neighbours have begun to teach me everything I need to know about the world of arigculture. I decided to start this blog to help others who plan to move out of the big city.
