Choose the Right Warehouse Forklift

Warehouse forklifts are best for raising and transporting crates, pallets and other materials over short distances. As their name implies, they’re often used in warehouses for loading and unloading inventory as well as picking and stacking. They can handle heavy loads and operate on indoor surfaces or smooth outdoor surfaces.

Warehouse forklifts come in different types. If you need the ability to move loads to the side, look for a side loader or a warehouse forklift with an available side-shift attachment. A walkie stacker is a walk-behind forklift designed to move and stack pallets at greater heights than a standard pallet jack. For the highest reach, choose a quad mast forklift.

Choose the correct forklift capacity

Choose a forklift with sufficient maximum capacity and make sure it can fit where you need it to go.

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 large forklift rental. In the case of forklifts with telescopic booms, consult the load chart to figure out the forklift’s load capacity.

United Rentals offers warehouse forklift rentals with a wide range of maximum capacities, including:

  • Small warehouse forklifts: A 3,000-pound warehouse forklift can handle light-duty to medium-duty jobs around a warehouse or other industrial site.
  • Medium warehouse forklifts: These have capacities ranging from 3,000 pounds to 15,500 pounds and are suitable for medium-duty to heavy-duty jobs. This 12,000-pound warehouse forklift can travel up to 12.1 mph under full load.
  • Large warehouse forklifts: With load capacities up to 55,000 pounds, large forklifts can handle heavy-duty applications.

In addition to capacity, you’ll also need to consider the forklift’s dimensions in relation to the space restrictions of the jobsite. For example, if you’re working in a warehouse, knowing the aisle width and/or common pallet dimensions will help to determine the size and type of forklift to rent. Pallet jacks and side loaders are ideal for narrow aisles.

Know the lift height you need

The height to which you need to lift materials will determine what not only what type of forklift you need to rent but also the type of mast you need (straight or extending, and how many stages). Forklift masts are typically two-stage or three-stage, though some are four-stage (quad masts). Quad masts are designed for the highest stacking.

Remember to consider your overhead clearance, including doorways, and make sure the mast (or boom in the case of a telehandler) at its lowest height will fit. Four-stage masts collapse to a lower height than other masts.

Choose a lift truck with the right tires

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

Forklifts with pneumatic tires, filled with compressed air, can handle rough terrain and uneven surfaces, including those found on construction sites and in lumberyards. Forklifts with pneumatic tires are typically intended for outdoor work, though they can also be useful in large warehouses. Cushion tires, made from solid rubber, provide less traction and lower ground clearance and are intended for indoor floors and smooth, level outdoor surfaces.

Choose between electric, diesel and gas/LP power

You need to decide the best power option for your site and project. Electric, diesel/gasoline and propane forklifts all have their advantages and disadvantages. When looking for the right rental forklift, start by thinking about the tasks the forklift will be used for. Will the work happen mainly inside or outside? Is moving heavy pallets the number one need, or will the operator be using attachments to do other work? What is your budget?

Electric forklifts

For indoor work, consider renting an electric forklift. Electric-powered forklifts are often used to lift and transport materials in industrial or warehouse settings, especially in cold-storage facilities for food and medical equipment.

If “battery-powered” makes you pause, consider this: Sealed lead-acid batteries have better starting power, recharge more quickly and have lower maintenance costs than older lead-acid batteries. Many heavy-duty forklifts still rely on lead-acid batteries because these heavy batteries — weighing between 800 and 4,000 pounds — serve as a counterbalance to the material being lifted. Newer electric models rely on lithium-ion batteries, which are the lightest option.

The pros of electric warehouse forklifts
  • Quiet, exhaust-free operation
  • Relatively low operating costs
  • More compact than propane or diesel thanks to the lack of an internal combustion engine
  • Maneuverable, can turn on a dime
  • Controls are basic, a boon for new or less experienced operators
  • Less downtime due to fewer moving parts and the absence of engine oil, coolants, filters and fuel
  • Less vibration, which reduces operator fatigue
  • Great performance from the AC motor
  • Performance not affected by cold temperatures needed for cold storage


The cons of electric warehouse forklifts
  • Most electric forklifts not rated for outdoor use
  • Higher costs than propane and diesel forklifts, and charging bays, chargers and tools for removing large batteries add to the costs
  • Heavy-duty work may require more expensive batteries
  • Batteries require recharging, which can slow down work and diminish runtime


Propane forklifts

For quick refueling and low emissions, propane forklifts deliver. Liquid propane (LP) powers the internal combustion engine. Propane forklifts come in many sizes and capacities and are used in trucking and logistics, manufacturing and large warehouses.

If you're considering renting a propane forklift, weigh these pros and cons.

The pros of propane warehouse forklifts
  • Can be used for work indoors or outdoors, even on inclines
  • Fast refueling (replacing a sealed propane tank takes five minutes or less)
  • Lower emissions than diesel
  • More power, greater torque and superior runtime than electric
  • Wide range of capacities
  • Longer engine life than diesel


The cons of propane warehouse forklifts
  • Fuel costs are unpredictable
  • Propane is volatile and can leak from tanks if tanks are punctured
  • More moving parts increase maintenance costs compared to electric
  • A clutch is used to slow traction speed so you may need to train drivers on loading and off-loading
  • May be difficult to start in cold weather
  • Less power and torque than diesel or gas models
  • Louder than electric forklifts


Gas/diesel warehouse forklifts

Need a bigger, more powerful forklift that can work on a slope? Renting a diesel or gas forklift is the way to go. These machines are the go-to outdoor forklifts for heavy-duty applications, such as heavy manufacturing, lumberyards and construction. Gas-powered forklifts are less common than diesel-powered forklifts but share many of the pros and cons.

The pros of gas and diesel warehouse 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 warehouse forklifts
  • Limited to outdoor use due to exhaust fumes
  • Noisy operation and vibrations cause operator fatigue
  • Can’t make short turns or work in tight places due to their size
  • Require more highly trained operators
