Rough terrain forklifts don't have the largest capacity, but they are meant to be driven across the most challenging outdoor terrain. Choisissez un chariot élévateur à fourche d’une capacité maximale suffisante et assurez-vous qu’il peut s’adapter à l’endroit où vous en avez besoin Think through what materials you plan to lift (single pallets? heavy containers? wood?) and the heaviest loads you'll need to lift. It's common for people to underestimate the capacity of the forklift they need, so when in doubt, go for a larger rough terrain forklift rental. For forklifts with telescopic booms, consult the load chart to figure out the forklift's load capacity.

United Rentals offers rough terrain mast forklift rentals and reach forklift— or telehandler — rentals with a wide range of maximum capacities, including:

• Small rough terrain telehandler forklifts: This4,500-pound telehandlercan handle medium-duty jobs around an outdoor site and travel on inclines, rocks or mud.
• Medium rough terrain forklifts: These range from 6,000 pounds to 10,000 pounds and are suitable for medium-duty to heavy-duty jobs. This 6,000-pound mast forklift has large pneumatic tires to transport materials where you need them.
• Large rough terrain forklifts: With load capacities between 12,000 and 23,000 pounds, large rough terrain forklifts can handle heavy-duty applications.

In addition to capacity, you'll also need to consider the forklift's dimensions concerning the space restrictions of the jobsite.

The height to which you need to lift materials will determine the type of forklift you need to rent and the type of mast you need (straight or extending, and how many stages). Les mâts de chariot élévateur sont généralement de deux ou trois étages, bien que certains soient de quatre étages (mâts quadruples).

Remember to consider your overhead clearance and ensure the mast (or boom in the case of a telehandler) at its lowest height will fit. Les mâts quadruples se rétractent à une hauteur inférieure à celle des autres mâts.

Most forklifts have a specific type of tire, so chances are, if you're using the right forklift for the terrain, it will have the right tires.

Rough terrain forklifts typically have large pneumatic tires filled with compressed air to handle rough terrain and uneven surfaces. Forklifts with pneumatic tires are typically used for outdoor work. If you need indoor work, a warehouse forklift with cushion tires, made from solid rubber, provides less traction and lower ground clearance and is intended for indoor floors and smooth, level outdoor surfaces.

Because rough terrain forklifts are ideal for outdoor use, they are typically gas or diesel-powered. Diesel-powered forklifts are bigger, more powerful than the smaller models working in warehouses or indoor industrial sites. Diesel-powered mast forklifts are the go-to for heavy-duty applications, such as heavy manufacturing, lumberyards and construction. Gas-powered forklifts are less standard than diesel but share many pros and cons.

The pros of gas and diesel rough terrain forklifts

• More power and torque than electric or propane forklifts
• Can lift more weight and easily power hydraulic attachments
• Faster acceleration and lifting
• Require less maintenance than propane-fueled engines
• Run time is limited only by fuel accessibility

The cons of gas/diesel rough terrain forklifts

• Limited to outdoor use due to exhaust fumes
• Noisy operation and vibrations cause operator fatigue
• They can't make short turns or work in tight places due to their size
• Require more highly trained operators
