Choose the Right Hydraulic Outrigger Stabilizers for Your Crane Truck

The information in this post is extremely useful for those who are operating a vehicle that would benefit from more stability when their crane is in work mode.

Outriggers and Their Main Functions

The main function of outriggers, which are also commonly called stabilizers, is to keep a truck and crane unit stable while in operation. This is often accomplished by using a single set of outriggers, but in other cases, adding auxiliary outriggers can create an even more stable platform for handling materials during load and offload.

The additional support provided minimizes shifting and leaning creating much less stress on both the crane operator and on the equipment.

The Important Role of Outrigger Stabilizers

Another important benefit of the second set of outrigger stabilizers is the reduced wear and tear on the crane rotation system due to limited side loading. Studies have indicated that additional repair costs and loss of productivity occur from operating cranes without adequate outriggers in place.

Further information will be posted each week on each of the different styles of hydraulic outriggers and stabilizers that are commonly used on different service trucks and trailers.

We would be pleased to provide more information or answers to any specific questions.  To talk to a specialist on hydraulic outriggers, please call Drive Products.

Are Winches Required on Small Truck Cranes?

Small crane trucks (with a lift capability of 5,000 lbs or less) are available in two designs. The first is a fixed boom (davit type) crane. The second is a crane with an elevating (articulated) arm. On a fixed boom crane, a winch is usually employed to do the lifting. The modern alternative is a crane with a pivoting (articulated) arm that lifts on the hook attached to its outer end.

Either type can be installed on service trucks such as flat decks, tire service, propane delivery and larger pick-up trucks.

Most operators consider an articulated crane the simpler of the two types to operate because he/she needs to focus on the movement of the boom tip hook and load movement. The operator of a winch equipped crane on the other hand, must pay attention to the winding of the winch line onto the drum as well as its movement through any sheaves.

An advantage of winch equipped cranes is that they can lift in a straight line, close to the column, while cranes with articulated booms lift through an arc of varying distance from the column.

However, because BIGMAX cranes feature booms that extend (telescope) as well as elevate hydraulically, they offer most of the advantages of winch equipped truck cranes without their operating complexities and extra costs.

What is meant by crane ‘Lift Moment’?

Important to know when searching for a truck with crane is understanding the lift capability.

The term ‘lift moment’ is the load capacity of the knuckle boom crane in either tonne-metres (t/m) or foot-pounds (ft.lbs.). For example, if you need a truck crane to lift 2000 lbs. at a distance of 10 feet, then your crane must be rated at (or have a lift moment of) 2000 lbs @10 feet, or 20,000 foot-pounds.

BIGMAX TC mono-boom cranes are compact to install with a telescoping boom. The lift moment for the smallest TC 100 crane is 6,710 ft. lbs. This crane can lift 1,890 lbs and its maximum reach is 12 feet.  The largest TC 350 crane has a lift moment of 24,900 with a maximum reach of 23 feet and a maximum lift of 5,297 lbs.

Advantages and disadvantages of DC electric powered small booms

The main advantage of a DC powered crane over a hydraulic crane on a boom truck is ease of installation. For example, since BIGMAX electric cranes come with their own battery operated power pack, the crane can be mounted on any vehicle including trucks, trailers, and boats which has an adequate battery and sufficient stability. No separate, often costly hydraulic system is required as on a hydraulic crane.

The main disadvantage of DC powered cranes on boom trucks is that, because it is battery operated, the crane has a limited duty cycle. While ideal for more occasional use, a battery powered crane can usually run for 5 minutes every 20 minutes or so, depending on the battery strength and whether the battery is being constantly charged.
