Preguntas frecuentes sobre los polipastos
Whether you need an air chain hoist or a come-a-long, United Rentals carries a collection of hoist rentals to meet the needs of your project. Hoists are designed to efficiently lift heavy materials by way of a wheel or drum and a chain or rope. Additionally, we offer many different types of hoists, used across a wide variety of industries. For example, electric chain hoists hook onto nearly anything, making them great for lifting and lowering heavy loads in tight areas that traditional lifts can't access. Grip pullers are smaller than a come-a-long and use wire rope to similarly lift, pull, lower or stretch your loads. Whether you’re looking for a hoist to help replace engines, lower materials or shift turbines, our selection is sure to have a match.

No, an aerial lift is a work platform meant to lift personnel for work at height. Un polipasto eleva o baja una carga usando una cuerda o cadena envuelta alrededor de un tambor en un sistema de poleas que se alimenta manualmente o mediante un motor hidráulico, eléctrico o accionado por motor.
