The 15t PROLH from Tiger
Yale’s CD85
lever hoist can lift 10t
Yale’s Mini 360 fits in the palm of the hand
weight, despite its load capacity of
1,000kg. Suggested applications are repair, assembly or maintenance work. Kito says the product is answering a
great demand for compact hand chain blocks. “Almost all users choose a hand chain block for mobile applications by two criteria, the dead weight and the load capacity,” says the company, “because you need as little weight as possible and as much power as possible at the same time. On this account, the small and compact Kito CX is available in three different versions. The Kito CX010, weights 7.3 kg and has a load capacity of 1 ton, offering application with heavy loads. 250 kg and 500 kg capacities are others in the range. On all three models the housing is compact and made of aluminium. Inside the housing is high-quality, two-stage precision gearing. A heat-treated steel frame serves as a stable bearing for the gearwheels; the gearwheels themselves are cold forged for maximum and constant performance. The chain sprocket casting is precisely matched to the gearbox so that the nickel-plated load chain is carried flawlessly. The intent has been for a small but strong construction. And the CX010 has an unusual feature.
As small hand chain blocks are often transported and used in several places, it is provided with a ‘Twist Checker’ as

part of the standard equipment. It is a small tool that determines quickly and easily if the load chain is twisted or if the hoist can be used directly out of the toolbox. It would seem a genuine improvement for the daily work routine.
LEVER OR CHAIN? Having opted for manual power, another choice remains: should it be a chain hoist, or a lever one? There are pros and cons for each. Chain hoists can lift heavier loads than lever hoists. On the other hand, “a lever hoist is more portable,” says William Hackett’s Burgess. There is less chain to fit into the above-mentioned toolbox, and to get tangled when pulling it out. “Lever hoists are better for pulling or tensioning applications.” A lever hoist can be used for pulling horizontally as well as vertically, which most chain hoists cannot. Indeed, data from Columbus McKinnon
seems to show that lever hoists are used more often for pulling – say to help tighten the securing straps on a load - than for lifting; chain hoists generally must be used for vertical lifting, or at least lifting limited to within a certain angle from the vertical. Chain hoists need two hands to work them; lever hoists can be operated one-handed. But with a lever the operator has to stand right next to the device and to the load, which can be hazardous – and the device
has to be low enough for him or her to reach the lever from the ground; with a chain device a long length of pulling chain allows the operator to stand well away to the side, or to work a ceiling- or trolley- mounted hoist mounted some distance overhead.
CAPACITIES We have said that chain hoists can lift heavier loads. Ten to 15 tons is about the limit for lever hoists. The Yale C/D85 from Columbus McKinnon can lift 10 tons; the Tiger PROLH (which stands for Professional Lever Hoist) range goes up to 15 tons. William Hackett’s WH-L4 lever hoist includes models with working load limit ranges from 800kg up to 15 tons. Double safety twin pawls are fitted as standard.
SPECIAL ENVIRONMENTS Most of the above are intended for standard, normal, everyday surroundings. But manual hoists, like powered ones, come in versions specially adapted for difficult or hazardous environments. Extreme temperatures are one such: in many regions – Scandinavia, Canada, the northern United States – hoists must function in temperatures below -20°C. Examples include assembly or repair work, for example of cable cars in mountainous regions, oil and gas production in the North
