LS-60TD PUMP — TOWING SAFETY PRECAUTIONS
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:
TOWING SAFETY PRECAUTIONS
Check with your county or state safety towing
regulations department before towing your
concrete
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 55 MPH, however
before towing your pump, check your local state, and
county vehicle towing requirements. Recommended off-
road towing is not to exceed 15 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 5 (Tire Wear
Troubleshooting).
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 6,000 lbs. (2,720 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 40. 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 wear 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 6.
■ 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.
CAUTION - LOCAL TOWING REGULATIONS
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.
CAUTION - DAMAGED TRAILER COUPLER
