TOWING GUIDELINES
To reduce the possibility of an accident while transporting the
pump on public roads, always make sure that the trailer and the
towing vehicle are in good operating condition and both units
are mechanically sound.
The following list of suggestions should be used when towing
the pump:
■ Make sure that the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weight rating" (GVWR).
■ ALWAYS inspect the hitch and coupling for wear. NEVER
tow the light tower's trailer with defective hitches, couplings,
chains etc.
■ CHECK the tire air pressure on both the towing vehicle and
the trailer. Also check the tire tread wear on both vehicles.
■ ALWAYS make sure the trailer section of the pump is
equipped with a "Safety Chain".
■ ALWAYS attach trailer's safety chain to frame of towing
vehicle.
■ ALWAYS make sure that the vehicle and trailer directional,
backup, brake, and trailer lights are connected properly and
are working properly.
■ Remember in most cases the maximum speed unless
otherwise posted for highway towing is 45 MPH, however
before towing your pump, check your local state, and county
vehicle towing requirements. Recommended off-road towing
is not to exceed 10 MPH or less depending on type of terrain.
■ Place chocked blocks underneath wheel to prevent rolling,
while parked.
■ Depending on soil conditions and location it may be
necessary to place
support blocks underneath the trailer's
bumper to prevent
tipping , while parked.
■ Inflate tires to correct pressure, inspect tires for cuts, and
excessive wear. See Table 3 (Tire Wear Troubleshooting).
Towing Safety Precautions
Pump Trailer Vehicle Connection
1. Check the vehicle hitch ball, and trailer coupler for signs of
wear or damage. Replace any parts that are worn or
damaged before towing.
2. Use only the 2-inch ball diameter with a towing capability of
5,000 lbs. (2,268 kg) as indicated on the trailer's coupler.
Use of any other ball diameter will create an extremely
dangerous condition which can result in separation of the
coupler and ball or ball failure.
3. Be sure the coupler is secured to the hitch ball and the lock
lever is down (locked).
4. Attach safety chains as shown in Figure 2. Remember to
cross the safety chains.
5. After towing for about 50 miles recheck the entire towing
system for tightness.
Recommended Maintenance
1. Smear ball socket and clamp face with chassis grease.
Periodically oil pivot points and were surfaces of coupler
with SAE 30 W motor oil.
2. When parking or storing the concrete pump, keep the coupler
off the ground so dirt and other debris will not build up in the
ball socket.
■ Check wheel mounting lug nuts with a torque wrench.
Torque wheel lug nuts as described in the "
Lug Nut Torque
Requirements
", Table 5.
■ Make sure brakes are synchronized and functioning properly.
■ Check tightness of suspension hardware (nuts and bolts).
■ Avoid sudden stops and starts. This can cause skidding, or
jackknifing. Smooth, gradual starts and stops will improve
gas milage.
■ Avoid sharp turns to prevent rolling.
■ Retract wheel stand when transporting.
■ DO NOT transport pump with fuel in the fuel tank.
If the trailer coupler is deformed replace entire coupler. NEVER
tow the pump with a defective trailer coupler. There exist the
possibility of the trailer separating from the towing vehicle.
Check with your county or state safety towing regulations
department before towing your concrete pump.
