Construction Hoist

Construction Hoists Buying Guide

A construction hoist is a material hoist, not a personnel hoist. These machines lift material, and the distinction is a legal one, not a matter of preference. OSHA's construction rule for material hoists, 29 CFR 1926.552, requires a posted "No Riders Allowed" sign and bars anyone from riding the hoist except for inspection and maintenance. A builders hoist raises block, mortar, tools, and buckets up the face of a scaffold, and it never carries a worker. Keep the load path clear below the hook, keep people off the landing zone during a pick, and treat the rated capacity as a ceiling you do not test. Everything else in this guide assumes the hoist is moving material and only material, because that is the job these units are built and certified for.

Size the capacity, then look at the speed. Capacity and speed pull against each other on these units, and it is worth understanding the trade before you buy. The OZ Lifting OBH500 lifts 500 lb at 75 feet per minute, while the OBH1000 doubles the capacity to 1,000 lb but slows to 37 feet per minute because it reeves the rope for the heavier pull. Our Vestil electric rope hoists split the range finer, at 300, 500, 700, and 1,000 lb, all on 115V power. Total the load honestly: the material plus the bucket, the hook, and any rigging, then round up to the next rating. If the job is repetitive light loads up a low rise, the faster 500 lb unit moves more material per hour. If the picks are heavy, buy the capacity and accept the slower rope. Do not size to the single heaviest pick of the year and then crawl through a thousand light ones.

The mount is the decision that defines a construction hoist. This is where a builders hoist earns its name, and it is the part buyers most often underspec. The hoist is only as safe as what it hangs from, and the collection carries every common way to attach one. The scaffold mount bracket bolts the hoist to a standard scaffold tube and is the default on tube-and-clamp or system scaffold. The wall mount bracket anchors it to structure when there is no scaffold to use. The beam clamp, rated to 1,000 lb, grabs the flange of an I-beam with no drilling. The swing arm clamp lets the hoist pivot out past the edge so the rope clears the deck and drops cleanly to the ground below. Whatever you choose, the structure has to carry the load with margin. OSHA requires a scaffold and every component to support at least four times the maximum intended load under 29 CFR 1926.451, so a fully loaded 1,000 lb hoist plus its own weight has to sit on a scaffold rated well beyond that. Confirm the scaffold rating and the bracket rating before the first pick, not after.

Move the load sideways with a trolley. A fixed mount lifts straight up and down, which is fine until you need to land material a few feet inboard from the rope line. A push beam trolley carries the hoist along a beam so you can spot the load over the deck instead of over the edge. We stock push beam trolleys sized for the OBH500 and OBH1000, including a half-ton trolley that also fits the OBG gantry frame. Pair a trolley with a beam that spans the opening and a vertical hoist becomes a short horizontal handling system. That is often the difference between setting a pallet of block where the masons are working and dropping it at the edge for a second manual carry, which is the lift that hurts people.

115V power and 90 feet of reach. Every construction hoist here runs on single-phase 115V, the same power as a job-site outlet or a portable generator, so there is no three-phase drop to arrange. The OBH1000 ships with a 15 ft power cord and a 65 ft control pendant, which lets the operator stand clear of the load and still reach the buttons from a lower landing. Ninety feet of wire rope is the standard drum length across the OZ and Vestil units, enough for most low- and mid-rise work. Measure your lift height and add the slack you need to reach the ground with the hook, because usable lift is always a little less than the total rope wound on the drum.

Controls, braking, and when to step up to a different hoist. The OBH builders hoists come with a wired pendant, upper and lower limit switches that stop the drum at the top and bottom of travel, a dynamic brake that holds the load when the button is released, and a 360-degree swivel hook. If the pendant cord gets in the way, the wireless plug-and-play adapter converts the same hoist to remote control. A construction hoist is built for temporary, portable, outside-the-building work. When the lift is permanent and lives in one bay, an electric wire rope hoist or an electric chain hoist wired for the shop is the better long-term buy. Match the machine to the job: rope up the scaffold for the build, a fixed hoist on the beam once the building is standing.
