ST-45 PUMP — IMPORTANT HAND SIGNALS Figure 1 display's the basic hand signals commonly used in concrete pumping operations. Figure 4 Operation Hand Signals PAGE 16 — MAYCO ST-45HRM PUMP — OPERATION & PARTS MANUAL — REV.
ST-45 PUMP — GENERAL INFORMATION Concrete Mix Design There are four ways in which this seal can be lost: 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.
ST-45 PUMP — 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. It is impossible to define a specific mix for each region that the Model ST-45 be will working in. Therefore, the mixes on pages 58-59 will provide a basic guideline for establishing the proper mix design for your area.
ST-45 PUMP — HOW IT WORKS The 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.
ST-45 PUMP — PUMP COMPONENTS Figure 7. Major Pump Components PAGE 20 — MAYCO ST-45HRM PUMP — OPERATION & PARTS MANUAL — REV.
ST-45 PUMP — PUMP COMPONENTS Figure 7 illustrates the location of the major components for the ST-45 Structural Concrete Pump. The function of each component is described below: 13. Lubrication Panel – This console allows for the remote lubrication of components on the pump. 14. Rear Running Lights – ALWAYS check and make sure both the right and left running lights are functioning correctly before towing the pump. 1. Tow Hitch Coupler – Requires a 2-inch ball hitch or a 3-inch pintle.
ST-45 PUMP — CONTROL BOX COMPONENTS Figure 8. Pump Control Box Components 1. Engine Tachometer – Monitors the engine RPM’s and hours of operation for the engine. 2. Emergency Stop Button – Press emergency stop button to stop pump in an emergency.Turn knob counter clockwise to disengage the stop button. 3. Hourmeter – Display's the number of hours the pump has been in use. 4. Ignition Switch – Insert the ignition key here to start the engine.
ST-45 PUMP — ENGINE COMPONENTS Figure 9. Pump Control Box Components INITIAL SERVICING The pump's engine (Figure 9) must be checked for proper lubrication and filled with fuel prior to operation. Refer to the manufacturers Engine manual for instructions & details of operation and servicing. 1. Muffler – Used to reduce noise and emissions. NEVER touch the muffler while it is hot! Serious burns can result. NEVER operate the engine with the muffler removed. 2.
ST-45 PUMP — OPERATING PROCEDURES C. If it is necessary to wait 10 minutes or more for another load of concrete, it is wise to start the pump and pump 6 or 8 strokes every 5 minutes to prevent setting of the mix in the system. If waiting time is excessive, it would be wise to wash out the pump and hoses and start over when the new truck arrives. OPERATING SUGGESTIONS 1. A well-planned location of the pump and routing of the hose before starting a pour may save subsequent moves throughout the job. 2.
ST-45 PUMP — OPERATING PROCEDURES WARNING B. MBVR – air entraining, acts as a lubricant. Common sense tells us that if you drive a truck into a brick wall, something is going to be damaged. The same holds true with your concrete pump. If you repeatedly pull the throttle all the way out and try to force your pump to push through blockages due to separation of material in the hose or manifold, you will soon have breakdowns and costly repairs which are not covered under warranty.
ST-45 PUMP — OPERATING PROCEDURES C. Mix the prime to the consistency of a smooth batter. D. Position the first ready-mix truck at the hopper. Check the concrete. DO NOT discharge concrete into hopper at this time. The bentonite is not compatible with concrete. DO NOT pump it into the forms discharge it out of the formed area. NOTE 16. The shuttle tube is plugged if volume at the discharge end of the hose stops, the hose is soft and the hydraulic oil pressure gauge reads 3000 psi or more.
ST-45 PUMP — OPERATING PROCEDURES D. Carefully knock the end of the hose away from the reducer. E. Chip the concrete out of the reducer with the pry bar. F. Remove the reducer. From the discharge end, chip the concrete out of the shuttle tube with the pry-bar. If concrete cannot be loosened from the outlet of the shuttle tube, remove the clean-out plug on the bottom of the hopper to discharge the concrete. G.
ST-45 PUMP — OPERATING PROCEDURES Use a 25 ft. hose, or short section, off the pump; and for the balance of the horizontal distance to the vertical line, use steel pipe.This type of installation has been satisfactory on many jobs being pumped in excess of 100 feet high. Line pressures are always less using steel pipe as compared to hose. entire drive system and valving under simulated full load conditions.The pump owner can do the same by making an adapter to couple to the end of the discharge cone: e.g.
ST-45 PUMP — INSPECTION CAUTION NEVER operate the pump in a confined area or enclosed area structure that does not provide ample free flow of air. FUEL CHECK 5. Read the fuel sight tube (Figure 10) on top of the fuel tank to determine if the pump's engine fuel is low . ALWAYS wear approved eye and hearing protection before operating the pump . NEVER place hands or feet inside the hopper. ALWAYS make while the engine is running.
ST-45 PUMP — INSPECTION ENGINE OIL CHECK 7. Remove the engine oil dipstick from its holder (Figure 12). 12 The oil listed in Table 47 is recommended to ensure better engine performance.
