Custom Designed Plumbing Kits

Your attachment should give you production, versatility and reliability. No attachment can function effectively on a poorly designed hydraulic circuit resulting downtime and weak performance will cause you headaches and cost you money. Get a properly designed custom kit from the Merc Group Hammers. First class engineering and first class components mean you will get the best return on your attachment investment.

What Type of Kit Do I Need?

Single-Acting

Used for Breakers, Compactors and Rotary Cutters. These attachments process oil in one direction, and typically require low back pressure on the return line. Our kit typically returns direct to the hydraulic reservoir.

Double-Acting

Used for Shears, Crushers, Grapples and Thumbs. These attachments typically utilize a cylinder that must extend and retract. They require a circuit that can route oil bi-directionally.

Dual-Purpose

With the addition of some special valving, we can offer kits that are easily converted from Single to Double-acting, allowing your carrier to operate various attachments, for example, a shear and breaker.

Second Function

We stock special directional valves that make it easy to add more auxiliary circuits to operate, for example, a rotating function on a crusher.

Typical Circuit Components

Tubing

Heavy-walled (.200″), TIG welded, and pressure tested.

Hoses

Premium-quality assemblies – JIC hose ends are commonly available, for easy field replacement, if necessary.

Relief Valve

Massive, severe-duty, in-line pilot operated relief valve ensures accurate setting and trouble-free service life.

Special Components

Filters, accumulators, directional valves, flow control valves, solenoid valves, 3-way and 4-way ball valves, and other hard to find items are in stock.

Clamps

Massive cast assemblies that are custom made for severe-duty applications. Solid steel, no rubber or plastic parts to wear out.

Clamps

Very high pressure ball valves for durability, and easy installation and removal of attachments.

Pedal Valve

Proportional valve provides superior “feel” (important on double acting circuits), and is extremely durable and reliable. Electrical connections are eliminated. Joystick or foot switch controls are also available.
