Founded in 1991, Robert Hydraulique Inc. has over the years developed a line of innovative hydraulic aerial ladders with working heights from 35 to 50 feet.


Robert Hydraulique (RH) is a manufacturer of insulated and non-insulated hydraulic aerial ladders. Innovation, reliability and effectiveness characterize its line of specialized equipment and form the basis for RH’s outstanding and ever-expanding 
reputation in the industries it serves. 


Robert Hydraulique’s mission is to “develop market-specific products and create high-tech concepts that meet its clients’ most demanding requirements”. Emerging from these objectives are versatile, long-lasting hydraulic aerial ladders that can operate a wide range of application areas. And it’s these products and capabilities that form the basis for the growing success of RH equipment. 


Our hydraulic ladders are used in the following sectors: government projects, telecommunications, cable television, public works, electrical contracting, sign design and installation, tree trimming, and building and ski resort maintenance.

Robert Hydraulique obtained its first South Korean order for a new type of four-section ladder to be manufactured for a company based in Seoul. Contracts followed for numerous other components to upfit ladder trucks. Since then, more than 50 fire trucks in South Korea have been equipped with RH telescoping ladders. 


Also in 2005, Robert Desrosiers took a more active role in AMETVS (Specialty Vehicles and Transportation Equipment
 Manufacturers’ Association) and became the secretary of its Board of Directors. Within a year, he was promoted to Vice-Chair, and two years later he was elected Chair of the Board.

In 2006, Carl Desrosiers joined Robert Hydraulique team after having spent six years as a project manager for Expertech, a telephone network installer owned by BCE. Having grown up in the world of aerial ladder devices, he has the background and expertise to provide continuity in Robert Hydraulique’s management for decades to come.     


In 2008-2009, Robert Hydraulique created numerous new projects, including the development and production of a ladders  adapted for ski resorts (BR, see picture), cable-television-specific equipment (RH44T) and mainly, the first light version ladder with only two sections (RHL37).


Robert Desrosiers founded Robert Hydraulique in October 1991 with the objective of offering repair and maintenance services for hydraulic components and aerial ladder and bucket systems of all kinds. At the beginning, the company had only 3 employees and operated out of a shop facility on rue Charles-Marchand in Le Gardeur, Quebec. Those were the conditions when Robert Hydraulique carried out its first major contract, reconditioning several aerial ladder units for a large-scale telecommunications company. In just two years, rapid growth compelled Robert Hydraulique to move to a new location and increase its staff to about 20 employees. 

Around this time, Robert Desrosiers conceived of the idea of creating a hydraulic aerial ladder that would revolutionize the market. After selling its maintenance operation and expertise to RentWay (now operating under the name of Penske) in 1998, Robert Hydraulique tapped into five years of research and development to open a production plant and officially establish itself as a manufacturer of hydraulic aerial ladders. 


Success was almost instantaneous, with users quick to recognize the added value inherent in RH aerial ladders. The quality, strength, safety and many other advantages of these hydraulic ladders were clearly evident to bucket truck operators. Initially, RH telescoping ladders came in eight models (3 insulated and 5 non-insulated), with working heights ranging from 35 to 50 feet.

In 2009


In early 2009, Robert Hydraulique signed its first business deal in Africa with the sale of insulated telescoping ladders to an electrical company in Cameroon. The quality, strength and dielectric properties of the buckets were key points in the company’s procurement decisions. This is just one example of RH ladders being deployed and successfully operated in challenging conditions and environments. At the end of 2009 the RH team grow bigger and greet Aude Bélanger as the director of the engineering and conception department.

In 2010


After a long period of strategic negotiations, RH aerial equipment established a foothold in Indonesia, which has the potential to be a very promising market for Robert Hydraulique.    RH  also manage to add strategic member  in the organisation, Jonathan Lesage as the Director of operations. Young and filled with energy our team is ready to conquer the Aerial lift equipment market.

In 2011 the Quebec government (CGER/ Management Center of Wheeled Vehicle) approached us improve an existing product that was too heavy for our road during our more than generous thawing period. It was preventing them to work a month or two at a time and had to find a solution. Thriving on challenges, RH took the project under their wing and developed a similar but lighter and improved unit that was called RHP14. This unit isn’t our usual piece of equipment. It is a platform that can stretch to the side all the way to 16 ft, with a 26-degree elevation it can go all the way up to 14 ft.

In 2012


is the year of major advancements in Indonesia.  After multiple visits by Carl Desrosiers and Robert Desrosiers in South-East Asia, RH Ladder as establish an office base in Jakarta, built up a partnership with Adicitra who will assembly the RH bucket truck in their facilities in Surabaya, built and get the approval of a demo bucket truck by the employees of the national electricity company. And finally get the first significant order by the end of 2012 after three years of hard work with numbers of ours international relations.



was a decisive year;  big changes were made at RH to give the opportunity to fix new standards and to give the company the push to climb another step in its progression.  

In  2013 Decision was taken and needed. To push and offer a greater and consistent product, RH Equipment has to bring external restriction sub contracting limitation to internal production and quality control standard.


A new 20 000 ft2  production plant was built to  accomodate a much greater production capabilities and efficiency. 


Numerous tools and machine addition was also integrate in this facility such as, robot Welding, CNC mahining,  waterjet 5axis cutting table, pres brakes and more.


With new production line RH equipment has  growth their production capabilitise by more than 6 times with a better quality control and a 47% faster pace.


New capablilities gave a new lanch to development and new product that will show up few years laters.

2014 NAFFCO reached out to us to help them create a faster fire truck to assist in local airports. Here is a little piece of NAFFCO history so you know how important this step is. It is an enterprise that was founded in Dubai, UAE to become the world's leading producer and supplier of life safety solutions. They saw the importance and how useful of having easy access to multiple safety services,they specialized in offering complete solutions under one roof for all types of high quality firefighting equipment, mobile hospitals and airport rescue firefighting vehicles. That is where we fit in. Since we can mount our units on smaller (faster) vehicle, we installed an RHL37 on a Ford Service body with our aluminium bucket. 

In 2015


a new challenge was waiting. The  SOPFEU " Government Air Service Quebec ," was the request of 10 RHS34 . This is Last Provided UN - Who staircase self-leveling and facilitates the maintenance of UN aircraft. It's 10 Wonders Were Distributed Across Quebec, more particularly to the airport Jean Lesage. LORs of July 31, 2015 California lived a tragedy Appointed ` Rough Fire`` Who TOOK end November 5 , 2015. It was at this time FUT Who uses our aircraft - tanks and suddenly Done followed the RHS34 .

And to addition that year, SSAB with the program ’’My inner STRENX’’ approached RH to become partner and be the 3rd company is the world to be part of that program. My Inner Strenx™ is a program for manufacturers who are thriving to make the best possible products using Strenx™ performance steel. It’s also a way for customers, operators and end users to identify manufacturers and products made with superior steel and quality-controlled production. In the never-ending battle to improve the performance of our units, the use of Strenx® steel products, less weight wins. In order to refine our product line we knew we needed to use lighter and stronger steel that can be used in thinner dimensions. Strenx® performance steel became our solution to this challenge. SSAB call it a performance steel, because it adds performance beyond ordinary high-strength steel. With Strenx steel, we can justify more payloads, cut down on fuel consumption, CO2 emissions  and aerial lift users can improve their business by reaching higher, faster and further.

Innovation is the name of that big year. Why? In order to step up their game RH increase their engineering team to finalized, develop and create new products. With our engineering department, we have developed an innovative concept of distributing the overall aerial lift equipment weight on the entire vehicle, which creates increased structural strength of our unit. Moreover, beyond 50% of the aerial lift equipment has been optimized for this concept; the base, platform and internal structure in order to maximize the cargo space. This specific technic is applicable, at that point, on the Sprinter (Mercedes or Freightliner).

We are also very proud to announce that we are finally capable to install our units on the Transit T350 and the GMC Savana 3500 and yet to be respectful of all regulations  (CSA, OSHA, DOT, ANSI + more) and honour the body builder guide of each vehicle. We have also developed a system to embed in the floor our energy source to maximize the cargo space and meet the regulations (CMVSS/ FMVSS 105 & 126) in regards to the gravity center.

2016 continues

Innovation is the name of that big year. Why? In order to step up their game and now that our line of products is bigger than ever, RH greets in their growing team Isabelle Boulet to develop the US market and expend their horizon. New distributors are added to the RH family to service better this great country.  She succeeds in selling a unit to the DPW of Utica (NY) with our distributor Kurtz truck equipment.

That’s not all! October 1st becomes a significant date for Robert, Carl and Jonathan

After many years of pushing the company further and prove their professionalism their outstanding efficiency, Robert made the decision to give lead, to continue the venture and selling the manufacture to the key members. From that day on Jonathan Lesage (with RH since 2010) has become the president and Carl Desrosiers (with RH since 2006) the vice president of RH.  Along with an experimented and devoted team, filled with vibrant energy, their involvement remains the same, which brought success to the company. Even more so, it is the RH philosophy: safety, quality and sustainability! The only thing that will change is the name of the company for RH Aerial Lift Equipment instead of RH-Ladder (Robert Hydraulique) since they manufacture so much more than just ladders. We can count now about 20 different RH models insulated (dielectric) or not, platforms, auto-levelling steps, tow behind and without mentioning our classics and more.


Let’s start 2017 with a BANG!  It is during a discussion between RH Aerial Lift Equipment inc. and Cisolift Distribution inc. that the idea came to conceive a completely different and new piece of equipment a few years back. In association with Cisolift, RH equipment outdid themselves and developed this brand new product that answers a specific need of which was ceaselessly increasing, but no solution existed just yet; let’s welcome the RHR series, an insulated towable aerial ladder available in 3 models! It combines the versatility of the towable boom and the safety of insulation against electric shocks.
