How do I select the right crane capacity for my application?

Start by looking at this helpful MODEL SELECTION GUIDE and then read the following.

Crane capacity is typically stated in one of two ways:

Foot*Pounds / Overturning Moment - typically used when describing Pedestal cranes.

The Foot*Pound rating is independent of the Maximum Lifting Capacity of the winch itself.

For example: the ET10KX is rated for 10,800 ft*lbs.   The Maximum Lifting Capacity of the winch is 3,200 lbs (using snatch block to provide 2 part line).

- or -

Maximum Lifting Capacity - typically used when describing Mast cranes

For example, the CT2004FB is rated for 2,000 lbs.  It is able to handle 2,000 lbs a maximum of 3 feet from the center of rotation, making it a 6,000 ft*lb crane.

How to determine Foot*Pounds (Overturning Moment)

a)      Determine the WEIGHT of the load to be picked up.

b)      Determine the DISTANCE from the Center of Crane Rotation to the spot where the load is to be picked up.

c)      FOOT*POUNDS = DISTANCE x WEIGHT

Example #1:  2000 lb WEIGHT to be picked up at 10 feet = 20,000 ft*lbs

                       Venturo crane to be used = ET25KX or HT25KX

      Example #2:  1000 lb WEIGHT to be picked up at 20 feet = 20,000 ft*lbs

                             Venturo crane to be used = ET25KX or HT25KX

Note that in both examples, the required Foot*Pounds was the same.  It is important to determine the greatest Foot*Pounds requirement (“worst case scenario”) when selecting your crane capacity.

When considering a Ferrari Knuckle-Boom (Articulating) Crane:

To convert Foot*Pounds to Meter*Tonnes, divide by 7,260.

7,260 ft*lbs = 1 meter*tonne

In most cases the Foot*Pounds calculation will dictate the model of crane to be used, the GVW of the truck, and the type of body.

What size truck (GW) is recommended for my Venturo crane?

NOTE: It is the sole responsibility of the installer to insure that the total structure of crane, truck, and outriggers are structurally sound and that the completed vehicle has sufficient stability against overturning.

What does "meets ASME/ANSI B30.5 specifications" mean?

ASME B30.5 (also referred to as ANSI B30.5) is the official ANSI "safety standard for cableways, cranes, derricks, hoists, hooks, jacks, and slings" having a maximum rated capacity greater than one ton. Officially, "the standard presents a coordinated set of rules that may serve as a guide to government and other regulatory bodies and municipal authorities responsible for the guarding and inspection of the equipment falling within its scope".

In our industry, the "Construction and Characteristics" section (Chapter 5-1) of the standard has come to be used as a general crane design guideline. A few of the aspects addressed by the specification include:

• Minimum sheave diameter relative to wire rope diameter. This guideline helps prevent premature wear of wire rope.
• Wire rope design factor (Breaking strength = 3.5 x Working load).
• Device to prevent uncontrolled retraction of hydraulic cylinder in the event of a hydraulic system failure.
• Visible load rating chart.

How do I interpret Venturo's model numbers?

This is most easily explained using a few general examples:

ET10KX
ET = Electric (over hydraulic) Telescopic
10K = 10,000 ft*lbs
X = Power extension

ET25K
ET = Electric (over hydraulic) Telescopic
25K = 25,000 ft*lbs
Since there is no "X" suffix, this model does not have power extension

HT40KX-P
HT = Hydraulic (PTO powered) Telescopic
40K = 40,000 ft*lbs
X = Power extension
P = Proportional control
