From the beginning over forty years ago, in 1961, Liftmoore, Inc. has built truck
cranes for field service, material handling and many other uses. These first units
were small and used for handling motors, drums, drill bits and other items in light
trucks and in some automobiles. These products proved useful and the business
continued to grow and develop larger cranes for heavier jobs.
The first cranes were 12 Volt electric drive. These units started at 1000 lbs
capacity. Larger units were required and today they build electric cranes up to
6000 lbs maximum capacity. Some hydraulic cranes were built for special uses
and in 1988 the first production hydraulic crane was introduced. Today a
complete line of hydraulic cranes from 3200 to 10,000 lbs is available from
Liftmoore has maintained a quality product throughout its past and that tradition
continues today. By supplying a quality product and providing excellent customer
service, Liftmoore has grown from a company with only a local market to now have
distrobution throughout the United States and Canada.
Reduce Service Cost since Job is done quicker
2. Precision Hoisting
Accurate Locating of Equipment
Spot Load Anywhere within the Crane's Operating Radius
3. Reduces Injuries
Eliminate Manual Lifting of Heavy Objects
|Note: These are suggested requirements to support the crane but do not
guarantee meeting the stability requirements of OSHA 29 CFR 1910-180.
Outrigger packages and possibly counterweight will be necessary to use
the crane capacity at maximum reach. If the crane does not meet the
stability requirements at maximum reach it will be necessary to reduce the
rating over that range as required in OSHA 1910-180 which is specified by
SAE J765. The crane mounting must be structurally sound and anchored
to the truck frame. In addition, the truck manufacturer's certification
instructions must also be followed.
|An optional accessory for your Liftmoore crane
is radio control. Radio control is the most
convenient method for operating a crane. The
operator is free to move around while
concentrating on the suspended load and its
safe movement. This control is available on
electric cranes, on-off control hydraulic cranes,
and proportional control hydraulic cranes. If
you already own a Liftmoore crane, this radio
control can be retrofitted!
|We also install Jackstands, Outriggers, and Boom Rests, Pedestals, Mounting
Plates, and Radio remote controls.
The jackstands or outriggers must be used under every crane to keep it level
while in use. Keeping the crane level is necessary to minimize crane rotation
loads. This will increase component life on powered rotation cranes and will
make control of manual rotation cranes easier.
Outriggers are available with the following configurations:
Manual pull out with a manual crank for setting and retracting the outrigger
Manual pull out with hydraulic cylinder(s) for setting the outrigger
Hydraulic out with hydraulic down cylinders for easiest set up
Boom Rests are required for all power rotation cranes and are designed to hold
the boom in a nearly horizontal position.

|Use an Electric or Hydraulic Crane?
|Cranes are offered with two different power systems,
either hydraulic or electric powered. All models feature
power hoist winch and most models offer power boom
elevation, power rotation and power boom extension.
Whether to use an electric of hydraulic crane in an
application is a function of the use of the crane.
For field service applications which require very little
crane running time an electric crane works very well.
Examples of field service applications are mechanic's
trucks of heavy equipment dealers and road
contractors, welders bodies, and LP gas tank delivery.
The duty cycle of the electric motors is limited to 5
minutes in 30 minutes per motor. As the battery loses
power the voltage drops causing the motor to run slower
and heat up faster. This can damage the electrical
For extended duty applications the hydraulic crane is
required. One example of an application requiring a
hydraulic crane is unloading a trailer loaded with tanks
or pallets of material that must be unloaded quickly.
Another example is lifting objects long distances several
times. Note that the winch oil will heat up. This restricts
lifts to approximately 200 feet.
The duty cycle of hydraulic crane can be nearly
continuous. For heavier use the reservoir size needs to
be larger to prevent heat build up in the oil.
There are some advantages electric cranes have over
