Using a rough terrain forklift, you can easily lift mortar, brick, and block up to five stories high, even in muddy terrain. Two types of construction forklifts are available: mast and telescopic boom. Mast forklifts have a vertical frame on which the forks (and load) are raised and lowered. They're used in industrial warehouses, brick and block supply yards, and sometimes on construction jobsites. Telescoping boom forklifts have extendable booms that rotate upwards. Because they can both lift and reach, they're preferred by most masonry contractors. How do you select a forklift? First, determine the lift capacity and reach that you need. Next, make sure the unit has the maneuverability and traction your jobsites demand. Then decide what features you want. LIFT CAPACITY A forklift is of little value if it can't lift the load. Lift capacity is a function of the lift height and reach. The greater the reach, the smaller the lift capacity. SPEED Forklift productivity depends on travel speed and boom speed. Check the manufacturer's literature for the maximum travel speed for each gear. Most manufacturers rate the boom and lift speeds in feet per minute (fpm) for loaded and unloaded operation.
