MECHANICAL REPAIRS AND WELDING
Mechanical and Hydraulic Repairs in Montreal and Heavy Equipment Maintenance
Careful Repair and Maintenance of Heavy Equipment, Truck Mechanics and Hydraulic Systems
The road safety of heavy equipment and trucks is a priority for many contractors. Through its Rhinobac division, specialized in mechanical and hydraulic repairs in Montreal, Groupe Projet has carefully restored the mechanics and hydraulic systems of heavy equipment as well as Roll-Off and dump trucks since 2019.
We perform mechanical maintenance on dump trucks and heavy vehicles such as Roll-Off and Hooklift. Our team has the skills to install and assemble hydraulic systems. Clients also ask us to commission and install new equipment on their truck fleets.
We also sell all the parts required to install new Roll-Off systems or replace defective systems. We are committed to keeping you safe on the road.


Welding of Dry Material (Crd) and Shipping Containers: A Durable Solution
At Rhinobac, a division of Groupe Projet known for mechanical and hydraulic repairs in Montreal, we favour restoring dry material (CRD) and shipping containers to avoid shortening their service life. Our team relies on a durable solution: container welding. You can repair every component, including doors, walls, and floors. Our approach is efficient. We repair not only containers for dry materials (CRD) and shipping, but also Roll-Off trucks, trailers, and platforms.
Our Mechanical and Hydraulic Work for Trucks
Rhinobac, a division of Groupe Projet, provides mechanical and hydraulic repairs in Montreal for specialized trucks, dump bodies, and Roll-Off equipment. We handle diagnostics, repair, and load testing. Each assignment follows a documented process to reduce downtime and ensure a reliable return to service.
System Diagnostics
Complete inspection of pressures, flows, temperatures, code reading, load tests, and leak checks. The diagnostic report prioritizes root causes to guide an effective repair.
Cylinders and Rams
Disassembly, inspection, and overhaul of rods, seals, and bushings. Surface refinishing, replacement of critical parts, and bench testing to validate force and the absence of leaks.
Hydraulic Pumps and Motors
Assessment of internal losses, recalibration, and replacement of worn components. Flow and pressure measurement restores circuit efficiency and consistent movements.
Manifolds and Valves
Block cleaning, spool refurbishment, and safety valve adjustment. Correction of jerky movements and slow responses on lifting functions.
Hoses and Fittings
Custom hose fabrication with controlled crimping. Route optimization to limit abrasion, reduce pressure losses, and prevent premature failures.
Roll-off and Hooklift Systems
Repair of rails, rollers, hooks, and locks. Sequence synchronization, adjustment of limit sensors, and stabilization of loading and unloading cycles.
Powertrain, Brakes, and Suspension
Brake adjustment, restoration of air circuits, and service on springs, bushings, and shock absorbers. Work on clutches, transmissions, and shafts to eliminate vibration and noise.
Electrical and Controls
Sensor, harness, and module diagnostics. Parameter updates and checks of in-cab panels to ensure coherent function operation.
Preventive Maintenance and Commissioning
Oil changes, filters, oil analyses, and safety inspections. Functional load tests and quality control before returning the vehicle to service.
