ST-45HRM CE CONCRETE 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-45HRM CE CONCRETE 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 64-65 will provide a basic guideline for establishing the proper mix design for your area.
ST-45HRM CE CONCRETE 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.

Serious burns can result. NEVER operate the engine with the muffler removed. 2.
ST-45HRM CE CONCRETE PUMP— OPERATING PROCEDURES OPERATING SUGGESTIONS 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. 1.
ST-45HRM CE CONCRETE 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-45HRM CE CONCRETE 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 20.
ST-45HRM CE CONCRETE 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-45HRM CE CONCRETE PUMP— OPERATING PROCEDURES 19. Vertical Pumping – When pumping vertically up the side of a building, above 12.2 meters (40 feet), we would recommend the installation of steel pipe securely fastened at intervals as necessary to support the pipe. Ninety degree, long radius pipe sweeps should be installed at the top and bottom of the steel line. Use a 7.62 meter (25 ft.
ST-45HRM CE CONCRETE 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 shutdown the engine before performing any kind of maintenance on the pump.

ST-45HRM CE CONCRETE PUMP— TOWING INFORMATION 1.0 GENERAL INFORMATION In . order to maintain the function and safety of your trailer, only original parts of the manufacturers design must be used. Servicing should only be undertaken by qualified personnel. 1.1 TOWING LEVEL Ideally, the trailer should be towed level (Figure 37) and not with the draw bar leaning up or down excessively.
ST-45HRM CE CONCRETE PUMP— TOWING INFORMATION 1.4 CONNECTION TO TOWING VEHICLE First, check the compatibility of your 50mm Ball Coupling or Towing Eye with the Towing Jaw/Ball connection on your vehicle. Always fit the breakaway cable or safety chain in a loop, fastening back on itself, to a substantial integral point on the towing vehicle. Ensure that the effective length is as short as possible, but still allows articulation (e.g. for cornering) without applying the brakes or tension through the chains.
ST-45HRM CE CONCRETE PUMP— BRAKING SYSTEM 3.0 BRAKING SYSTEM 3.1 WHEEL JACKING On level ground, with the hand brake lever in the off position and overrun coupling draw tube shaft fully extended forwards, secure one wheel with wheel chocks. Position your jacking device behind the opposite wheel, as near to a main longitudinal chassis member as possible. Lift the wheel clear of the ground and secure with suitable axle stands. NOTE If not already connected, connect the Bowden (sheathed) cables to the brakes.
ST-45HRM CE CONCRETE PUMP — BRAKING SYSTEM 3.4 COUPLING AND TRANSMISSION SYSTEM Attach the opposite end of the outer cable to the anchor plate (Figure 41E) on the axle or draw bar, using the nut provided. Connect the inner cables to the compensator, locking the 2 plain nuts together in front of the compensator for each cable. If not already connected, attach the rear end of the brake rod to the compensator center hole.
ST-45HRM CE CONCRETE PUMP— BRAKING SYSTEM With the handbrake fully off, check that the spring store’s overall length is 185 to 190 mm and is not applying a force to the U shaped guide on the side of the overrun lever. Adjusting is by the nut at the front of the assembly. This procedure should only be necessary when replacement parts have been fitted.
ST-45HRM CE CONCRETE PUMP — BRAKING SYSTEM 3.5 BRAKE PARTS KNOTT COUPLINGS Brake shoes (Figure 42) are recommended to be replaced when the lining thickness measures less than 2mm, as it is likely that they will be worn out before the next service. Always replace both brake shoes together, regardless of the lining thickness on the other shoe. It is further advised that brake shoes should be ideally replaces as an axle set to avoid uneven braking from side to side.
ST-45HRM CE CONCRETE PUMP— BRAKING SYSTEM 4.0 ADJUSTABLE HEIGHT DRAW BARS 4.1 HEIGHT ADJUSTMENT/TIGHTENING JOINTS the principle of the joints is steel pegs engaging with mating dimples (Figures 44A and 44B), which can be seen between the joint plates. While securing the assemblies, the equipment should be “rocked” as the joint pins are tightened to allow positive location. 4.1 GREASING ADJUSTABLE JOINTS There is a grease nipple at each joint pin position 4.
ST-45HRM CE CONCRETE PUMP — BRAKING SYSTEM 5.0 WHEEL HUB ASSEMBLIES 5.1 INSPECTION Ensure the brake shoes (if braked) are clear of the drum with no interference. Clean the hub to remove any road debris. Rotate the hub slowly – there should be no roughness or restriction. Rotate the hub rapidly – There should be no rumble, rattle or high-pitched noises.
ST-45HRM CE CONCRETE PUMP— BRAKING SYSTEM 6.0 OVERRUN COUPLING ASSEMBLY The coupling is greased on assembly, but will require periodic maintenance to ensure a smooth operation of the braking system. Re-grease the shaft bearings via the grease nipples (Figure 46), provided at 9,656 km (6,000 miles) or 6-month intervals. Also ensure correct functioning of all pivots, levers, ratchets and the spring store assembly. Grease all points of movement. Nipples Bellows Figure 46.
