Whether you’re gutting an old bathroom or demolishing an entire home, you need a few good demolition tools. This includes a demolition hammer, which is a heavy-duty power application tool that uses a percussive action to tear down structures. Many demolition contractors choose an automatic quick coupler for their carrier so they can switch attachments more quickly, rather than getting off their machine and on the ground to change a shear or pulverizer.

Hydraulic Hoses

Hydraulic hoses must meet stringent standards to adapt to the high levels of pressure, loads and sometimes contorted positions that they encounter. They are used in demolition, mining and construction, oil industries, transportation equipment like excavators and backhoes, lifting equipment like jacks and more. They are designed to transport liquid hydraulic fluids. They have a three-layer general construction that includes an inner tube, reinforcement and cover. The inner tube is often made from PDFE, thermoplastic or synthetic rubbers that are compatible with the liquid it carries. The reinforcement is a coiled or braided wire set that supports the tubing and protects it from tears. The outer cover is made from rigid materials to protect the innards from abrasion, chemicals and weather. Field-attachable couplings can be screw-together or clamp-type. A screw-together coupling attaches to the hose with an insert that screws into the shell and a clamp-type coupling has a two or four bolts and nuts that clamp onto the hose OD.

Hydraulic Quick Couplings

Hydraulic quick couplings are used when hoses or attachments must be connected and disconnected quickly in high-pressure applications. They are designed for specific fluid applications and consist of two counterparts (male and female). When connected properly, they provide a perfect seal that allows the fluid to flow. When it comes to changing out demolition tools, like shears or pulverizers, an automatic hydraulic quick coupling makes the process much easier, cleaner and safer. This is especially important when it comes to the safety of operators who may need to disconnect a hose under pressure from the ground while also staying clear of dangerous equipment.

Hydraulic Hose Fittings

Using the wrong fittings can lead to leaking couplings or even bursting hoses. Use only fittings, crimpers and accessories that are specifically designed for your specific hose. There are two main types of hydraulic hose fittings: all-metal and O-ring. In all-metal connections, the metals of the mating halves create a seal by touching each other and applying pressure. O-ring hydraulic hose fittings, on the other hand, form a seal by compressing the O-ring between the two sides of the fitting. Flange hydraulic hose fittings work best with larger hoses that are going to be exposed to high levels of vibration, shock loads and heavy pressures. They can also be used in tight areas where there isn’t enough swing clearance for a wrench to reach the hose end. Always make sure that your hose and fittings have matching pressure ratings. Exceeding the recommended pressure can severely reduce a hose’s performance or cause it to fail entirely.
