general information Concrete Mix Design Mix design is most important to achieve maximum pumpability. Pumpability is affected by, among other factors, the type and gradation of aggregate used. Natural aggregates make a more workable mix and pump more readily than crushed aggregates. A blend of natural and crushed aggregates will produce a workable mix. The type and gradation of aggregates is equally important for workability as the size and percentage of coarse aggregates in the mix.
general information Regional Differences Concrete is made by mixing locally available rock and sand with cement and water. For this reason there are great differences in the pumpability of concrete from one region of the country to another. In addition, this Mayco Concrete Pump can be used to pump a large aggregate hard rock as follows: Pea rock (1/2" minus) pump with mixes being as low as 30% rock and 70% sand. (reference maintenance for recommendations on cleaning the pump.
general information Downhill Pumping Downhill pumping can be a difficult procedure on some jobs. The slurry procedure would be the same as explained Priming The Pump With Slurry Mixture section of this manual. It is suggested that a sponge approximately 2”x 4”x 6” in size be placed in the hose before the start of pumping. Wet the sponge before placing it in the hose to keep the slurry from running too far ahead of the concrete, which will reduce the possibility of separation.
general information Fill the hopper with water after making sure that all sand and rock have been removed from manifold. Operate pump at full throttle and the 3/8" diameter hole restriction will create sufficient back pressure to make thorough inspection of all moving parts. The Effects Of Heat And Excessive Time On Concrete: Hot concrete, commonly referred to as a hot load, is concrete that has been in the redi-mix truck in excess of 2 to 3 hours. On a hot day, this amount of time is even less.
general information Clearing The System After Mix Set Up If, for any reason, the mix should set up in the system, the following procedure is suggested: 1. Disconnect the hose from the pump and wash the pump out immediately. WARNING Hose Line Pressure When disconnecting hoses, use extreme CAUTION. The hose is under pressure. Hose could whip and cause severe bodily harm. 2. Reconnect the hose and fill the hopper with water. 3. Reconnect the hose and fill the hopper with water.
general information Reverse Pumping Procedure 1. Switch the pump into reverse. With pump speed at a medium-slow (approx. 12 strokes per min.) try to pull the “pack” back into the hopper with 5 or 6 reverse strokes. 2. Remix the concrete in the hopper. 3. Switch the pump into forward. If it is still plugged, repeat “Reversing” procedure three times. 4. If concrete still does not move, proceed to the Shuttle Tube Inspection Procedure. 6. Remove the reducer.
general information he following is a brief explanation of how the concrete cylinders, hydraulic cylinders, shuttle tube, valves and hopper work in sequence to pump concrete. The hydraulic pressure is generated by a variable volume, pressure compensated, axial piston pump that is driven by a diesel engine. The rod sides of the drive cylinders are hydraulically connected together creating a “slave circuit,” which allows hydraulic oil to transfer from one piston to the other.

trailer maintenance The following trailer maintenance guidelines are intended to assist the operator in preventive maintenance. Trailer Brakes Properly functioning brake shoes and drums are essential to ensure safety. The brakes should be inspected the first 200 miles of operation. This will allow the brake shoes and drums to seat properly. After the first 200 mile interval, inspect the brakes every 3,000 miles. If driving over rough terrain, inspect the brakes more frequently.
trailer maintenance ADJUSTABLE CHANNEL WARNING 5/8" X 11" X 5" BOLT Failure to maintain proper fluid level in the actuator may result in loss of braking action which could cause severe property damage, injury or death. Periodically check the actuator mounting fasteners for damage or loosening. Inspect the actuator for worn or damaged parts. As you are towing your trailer, be aware of any changes in braking quality.
trailer maintenance After removing the dust cap, cotter pin, spindle nut and spindle washer, remove the hub to inspect the bearings for wear and damage. Replace bearings that have flat spots on rollers, broken roller cages, rust or pitting. Always replace bearings and cups in sets. The inner and outer bearings are to be replaced at the same time. Replace seals that have nicks, tears or wear. Lubricate the bearings with a high quality EP-2 automotive wheel bearing grease.
trailer guidelines The following guidelines are intended to assist the operator in the operation and handling of a trailer. Shift your automatic transmission into a lower gear for city driving. Safety precautions should be followed at all times when operating a trailer. Failure to read, understand and follow the safety guidelines could result in injury to yourself and others. Loss of control of the trailer or tow vehicle can result in death or serious injury.
trailer guidelines DRiviNg CONDiTiONS When towing a trailer, you will have decreased acceleration, increased stopping distance, and increased turning radius (which means you must make wider turns to keep from hitting curbs, vehicles, and anything else that is on the inside corner). In addition, you will need a longer distance to pass, due to slower acceleration and increased length. Be alert for slippery conditions.
trailer guidelines iNOpeRaBLe BRaKeS, LigHTS OR MiRRORS Be sure that the brakes and all of the lights on your trailer are functioning properly before towing your trailer. Check the trailer taillights by turning on your tow vehicle headlights. Check the trailer brake lights by having someone step on the tow vehicle brake pedal while you look at trailer lights. Do the same thing to check the turn signal lights. See Trailer Wiring Diagram section in this manual.
trailer guidelines VI N TA G VIN TAG Figure B. VIN Tag Location To determine the “empty” or “net” weight of your trailer, weigh it on an axle scale. To find the weight of the trailer using an axle scale, you must know the axle weights of your tow vehicle without the trailer coupled. Some of the trailer weight will be transferred from the trailer to the tow vehicle axles, and an axle scale weighs all axles, including the tow vehicle axles.
trailer guidelines eMeRgeNCY fLaReS aND TRiaNgLe RefLeCTORS BaLL HiTCH COUpLeR It is wise to carry these warning devices even if you are not towing a trailer. It is particularly important to have these when towing a trailer because the hazard flashers of your towing vehicle will not operate for as long a period of time when the battery is running both the trailer lights and tow vehicle lights. A ball hitch coupler (Figure C) connects to a ball that is located on or under the rear bumper of tow vehicle.
