“Motor, gearbox and drum are arranged in one line so if there are any motor issues you just unscrew the motor block without removing any other parts. “All of our hoists, up to the strongest four-falls hoist with 63t capacity, are subject to the same, easy-to-maintain architecture,” says Riese. Kuli says easy maintenance is always important, but particularly for heavy equipment. Some customers use water bags to test 50t or 100t.” “For heavier lifts,” says Caldera, “you need to have testing equipment on site to do a proper functioning test. Smaller capacity hoists can be removed and sent to the manufacturer for inspection, says Koski, but larger capacity units are inspected and tested in situ. In the US, lifting equipment above a 3t capacity typically requires an annual inspection. “Sometimes they will over-engineer what they require in terms of capacity to ensure nothing goes wrong,” he says. “In common with other manufacturers, Street Crane goes to great lengths to ensure our designs fully comply but that is only half the story: end users must be equally rigorous in their use of lifting equipment.”Ĭaldera agrees safety is the highest priority for customers installing heavy lifting equipment. “The first consideration is always safety and compliance with regulations,” says Pimblett. No matter what the lifting capacity, the paramount concern is safety. In the past year I’ve seen 100 ton hoists ordered,” says Mark Koski, North American commercial leader at Ingersoll Rand. “Bigger ships have larger components and heavier loads so we’re building bigger and bigger hoists. Shipyards and ports are also specifying heavier lifting equipment as ships and propellers increase in size, and with that, fuel capacity. “Fifteen years ago the weight of most blowout preventer stacks (BOP) was 20-75t today they’re 50-150 or 200t so the equipment to handle them has to have a higher capacity,” says Gus Caldera, global business development leader, Rand Material Handling. Ingersoll Rand has noticed the super sizing trend in several industries, not least the oil and gas sector. “The underlying picture is that in the developed world, which has a shrinking heavy industrial sector, orders have declined but for us this has been more than offset by developing countries where the heavy industry is still growing and where we have increased our presence,” says director Andrew Pimblett. ![]() In the past 10 years Street Crane has experienced a 60% increase in orders for heavy lift cranes and hoists. “Demand for heavier equipment is rising, possibly because the production of larger components is increasing.” “Our customers are moving bigger pieces in larger halls, so the capacity and span of cranes is growing,” says Kuli export manager Oliver Riese. Super-sized container ships and oil rigs to energy plants, factories and warehouses, all require heavy lifting equipment and the hoist sector is keeping pace. Keren Fallwell reportsĪs so much in the world is getting bigger so demand for heavy manufacturing is growing, and lifting capacities are increasing. ![]() As demand for heavy lifting grows, manufacturers advise that success is all in the planning.
