The mechanical grapple is a kind of attachment that is commonly used in the front end of the excavator for the handling and loading of timber. We have briefly introduced the characteristics of the mechanical grapple and other information for you. This time we will talk about the three types of mechanical grapple for excavators, let's take a look at their differences.
mechanical grappler: Propelled by the bucket cylinder of the excavator, without additional hydraulic speed.
Non-rotating wood grabber: pipes need to be added to control the wood grabber during installation, and the front end of the wood grabber will not rotate when in use.
Rotary wood grabber: This kind of wood grabber is more common, and two sets of hydraulic valve blocks need to be added for control operation during installation.
The non-hydraulic rotary wood grabber is connected by the oil circuit of the excavator bucket cylinder. It does not need to add additional hydraulic pipelines and hydraulic valves. It is quick to install and use. This style of product is convenient for use by many excavator drivers. The selectivity is high and the price is relatively low.
The mechanical grapple with rotation needs to be controlled by adding a set of hydraulic valve blocks and pipelines to be used normally, and this product can be adjusted in multiple angles according to the special requirements of the construction operation, and the use is more ideal, high and efficient.
Hydraulic cylinders equipped with hydraulic wood grabbers are equipped with protection devices.
Of course, due to the development of excavator attachments, quick-hitch couplings are constantly improving. Now many excavators are equipped with a quick-change coupling to replace and load and unload different excavator attachments.
