The RH44D is an insulated telescoping ladder with a working height of 44 ft (13.41 m), comprising three ladder sections for optimal efficiency. Ideal for work requiring a longer reach (e.g., utility poles offset far from the road), it can be installed on more lightweight trucks to give them working heights and horizontal reaches normally associated with bigger rigs. The lift ring located at the end of the second section is a standard accessory and can lift loads of 550 lbs (250 kg) in any position, regardless of carrier vehicle. And that’s not to mention the many other benefits and options available to ensure that RH aerial ladder equipment meets your specific needs.

This type of aerial ladder must be installed on vehicles whose GVWR (gross vehicle weight rating) is greater than 9,500 lbs (4,309 kg). Outriggers are generally not required. However, given the variety of configurations possible, outrigger requirements must be confirmed by means of stability tests performed on your bucket truck.

The same applies to the bucket’s load-carrying capacity (in other words, the maximum weight authorized to be carried in the bucket). Specifically, this telescoping ladder is rated to carry 350 lbs (159 kg); however, its actual load-carrying capacity depends on the carrier vehicle.

We encourage you to contact Robert Hydraulique to obtain more information on the restrictions and factors to be taken into account when installing RH telescoping aerial ladders so that you can meet the highest standards in quality and safety.
