The RH44T is a non-insulated telescoping ladder with a working height of 44 ft. (13.41 m) and an amazing side reach of 32 ft. (9.90 m). This reinforced three sections ladder is built to side pull, assist line man for lashing and so many more.

The lifting ring is located at the end of the second section as a standard accessory and can lift up to 550 lbs (250 kg) in any position, regardless of carrier vehicle. Comes with a wider aluminium bucket for more working space and a -30˚ base for ground access.

This unit can be mounted on different chassis as long as the GVWR (gross vehicle weight rating) is greater than 17,500 lbs (7,938 kg) like Ford F550 or E550, Hino, Freightliner and so many more. Key in head option is available. Contact us to see what we can do for your preferred chassis and configuration.







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.


*** Always ensure that you are complying with all local regulations when installing bucket-equipped aerial ladders. Robert Hydraulique is not responsible for installations performed outside of its production facilities

The connection of the auxiliary battery isolates the vehicle’s aerial lift equipment. The unit will work without the vehicle engine on. In any case, it will affect the vehicle’s battery; it is actually an additional security because if the truck’s battery needs a little “boost”, due to the type of connection, it can feed of the auxiliary battery. All our units have a two-way splitter between the auxiliary battery and the vehicle. We make no modification to your vehicle, only a wire is connected to the alternator which is used to recharge the auxiliary battery when the vehicle is running.


In addition, we can provide additional security by adding a system such as Ozone-tech. This product requires removing the keys from the ignition; press an activator button to operate the unit. Ozone-tech is perfect for fleet owners that want to have some control over the fuel consumption. The system ensures optimum battery management and will turn on the engine if the vehicle needs to recharge the battery to its maximum capacity.

RH Ladder uses advanced structural optimizing simulations to ensure safety and  enhance toughness. Our engineering approach considers all attributes such as weight, resistance, quality, performance and  manufacturability. 



Accuracy is crucial to achieve consistent quality. RH Ladder uses waterjet and laser cutting, along with robotic welding to deliver constant precision and reliability.
