The RHL37 is a non-insulated telescoping ladder with a working height of 37 ft. (11.27 m). The “L” in RHL37 refers to the lightweight design of the ladder, which has just two sections for minimized weight and manufacturing costs. This unit provides an amazing side reach of 26.8 ft. (8.51 m). This model has no lifting ring.

As RH’s lightest model, the RHL37 reflects the firm’s commitment to R&D and its use of advanced technologies to reduce equipment weight without compromising safety. The use of STRENX steel comes in handy; you get the ruggedness and quality RH Aerial Lift Equipment is known for, great payload at a very attractive price. 

This unit can be mounted on many smaller chassis like the GMC Savana, Ford Transit, Mercedes Sprinter or vehicles with a GVWR (gross vehicle weight rating) greater than 9,500 lbs (4,309 kg). Contact us for more details.

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.



& Engineering

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.



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 its production facilities




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