  • Page 10: Engine

    Engine The power unit is either a Cummins diesel or a Ford gasoline engine. These water-cooled engines are designed for industrial application and are the best engines for the job. The engine is also the most costly, single piece of equipment on the machine. When referring to the manual for service recommendation, use those given for the most severe conditions.

  • Page 11: Mixer

    Strong-Mater Mixer (Dwg. #86000007) The Strong-Mate Mixer is a completely new idea in mixers...designed for mixing most varieties of cementitious materials. The Mixer is designed to give a MAXIMUM amount of agitation, complete dispersement of the cement sand, and admixtures in as short mixing cycle as is possible.

  • Page 12: Material Pump

    Strong-Master Pump Dwg. #86000020 The Strong-Master pump consists of three principle parts, i.e., the pumping elements, the suction housing for material storage and the drive assembly to transfer power to the pumping elements. The pumping elements for the grout machine consists of a 2R10-0 rotor and stator connected to the suction housing.

    400 hours of operation or more often after wear begins. It is easily done when the rotor is removed as one end is usually greatest so that it is not necessary to remove other end unless pinholes show wear. Inspect and replace worn pins and boot seals whenever rotor and/or connecting rod is inspected.

  • Page 14: Loading System

    Loading System Dwg. #11144001 A hydraulically powered bucket is used to transfer the cement and the aggregate from the ground, and dumped into the mixer. The bucket is secured in the travel position by a pin through the bucket arm. Caution: Failure to install SAFETY PIN prior to travel could result in the bucket falling causing extensive damage to the machine and possible personnel injury.

  • Page 15: Hydraulics

    Also in the system are pressure relief valves. These control the hydraulic pressure that can be exerted to the various components and thus the force. These have been reset at the factory and should not be adjusted without consulting Strong Mfg. Co., or a qualified hydraulic mechanic. Further discussion of the hydraulic system and components to follow.

  • Page 16: Maintenance

    Hydraulic System (Maintenance) The hydraulic system must be kept free of dirt. Inside the tank is a strainer mounted on the pump suction line. If it becomes clogged, the pump will malfunction due to starvation. Also, damage to the pump will occur if starvation continues.

When trouble in the hydraulic system exists, it is usually accompanied by excessive heat. The major sources of trouble are worn parts in the pump and/or motor causing excessive slippage and heat, oil too thin and breaking down causing excessive slippage, and worn valves parts or broken “O”...

    Grout Machine Trailer The trailer is equipped with 6000-pound capacity axles with brakes on both axles, electric brakes are standard, however, hydraulic brakes may be furnished on request. The standard hitch is a 2-5/16” diameter ball with option for Lunette eye. Tires are 235/85 R16 L.R.E. radials. Trailer weight with equipment is approximately 8800 pounds.

    • There are four alemites on the mixer, two on each end. These should be greased as described in “The Strong-Mate Mixer” section, and at the end of each day’s operation. • Check inside the mixer and hopper for foreign items.
  • Page 24 Optional: The hose reel is hydraulically powered. In order to remove the hose from the reel, the directional control valve lever must be in the “UP” position. This valve is located at the rear of the trailer, facing the rear of the machine, the valve is located behind the right fender. Remove only enough hose as needed for the day’s operation.

  • Page 25: Mixing And Pumping

    Caution: DO NOT disconnect material hose with hoses under pressure. Always run pump in reverse until pressure gauge read “0” PSI, or hoses become soft. Failure to do so could result in blockage or material blowing out under pressure and striking someone causing bruises, cuts, breaking of limb or possible loss or sight if material enters eye.

  • Page 26: Clean-Up

    3. Clean Up During design, emphasis was placed on making the machine simple to clean at the end of the day. The following is recommended procedure for clean-up practiced by Strong Manufacturing which has proven to be a time saver.
  • Page 27 • When all material is out of hopper, discharge dirty water from mixer into hopper. • Let pump continue to run, allowing material in the hose to be pumped until water is at end of hose. During this time, mixer man should again be cleaning mixer inside and out. Take special care to clean area around mixer door.
  • Page 28 • Push in kill button on control panel and turn key to OFF position. Caution: DO NOT perform any cleanup or maintenance that may expose any part of the body to moving or rotating parts with the engine running. Doing so exposes one to severe safety hazards that could result in cuts, bruises, loss of limb or even death.
