CXT Wire Rope Hoists

Aug. 3, 2010
Konecranes, Inc. offers the CXT® wire rope hoist as a versatile solution for crane, monorail, and replacement applications, with lifting capacities up to 80 tons. Backed by the largest global crane service network available, CXT hoists enhance ergonomics, ease of operation, safety, and extend the life of crane components. Compared to traditional designs, the compact design of CXT hoists, from Konecranes, allows for reduced hook approaches and maximizes the hook floor coverage. Compared to traditional designs, the compact design of CXT hoists, from Konecranes, allows for reduced hook approaches and maximizes the hook floor coverage. CXT cranes equipped with the low-headroom CXT hoists can be used in existing buildings with limited height clearances, allowing the crane to operate closer to walls and lift loads higher. Previously unused or under-utilized areas can also become productive workspace when cranes are modernized with the CXT hoists. This compact hoist design reduces headroom requirements by more than 15% on average. Designed to meet the demanding operation in high duty-cycle lifting applications, the advanced drive technology of CXT hoists includes two-speed hoist motors and variable frequency trolley drives for ease of operation while maintaining precise control of vertical and horizontal motions. CXT hoists are created with high-performance hoisting motors that offer exceptional power and superior cooling characteristics. The motors deliver the power necessary for a wide variety of lifting applications. CXT hoists from Konecranes help to increase the safety of personnel as well as the service life of crane components. Inverter controls deliver smooth starts, accelerations, and decelerations to minimize load swing and enable safe and accurate load positioning for travel motions. The large drum diameter reduces fleet angles, minimizes the hook drift during lifting and lowering, allows for minimized end-approach dimensions, and increases the lifetime of wire ropes. An overload limiting device, standard on every CXT hoist, protects against crane overloading. CXT hoists come standard with high-performance cast-iron rope guides that prevent dangerous cross reeving and provide balanced lifting. Safety and bottom-line reliability are enhanced by excellent power transmission and braking systems, as well as gears that are manufactured with hardened and ground gear fabrication. The high-performance brakes have an adjustment-free and dust-proof construction. Sized for safety, CXT hoist brakes can exceed one million duty-cycles of operation, ensuring trouble-free operation and low total cost of ownership. Safety is further enhanced by utilizing the anti-sway and hoist synchronization options available on CXT cranes. Even new or less experienced crane operators can control and position loads with precision and predictability by eliminating dangerous load swings that often occur when loads are moved. The optional hoist synchronization is an effective tool when multiple hoists are used together to lift long or difficult loads. Hoist synchronization keeps the lifting hooks at predetermined positions throughout the lifting process to maintain load control. CXT hoists are designed to handle a wide variety of lifting capacities, speeds, trolley types, duty classes, and options. Additional features include: hook activated upper limit switches; secondary hoist and drum brakes; true vertical lift and true lift reeving; inverter hoisting; load display on pendant, radio, or scoreboard; multiple hoist synchronization, monorail trolleys for patented or curved track systems; outdoor environment protection; IP-66 trolley motor protection; anti-collision protection; anti-sway systems; slack-rope detection; ControlPro advanced electronic systems monitoring; and more. CXT hoists are available with Low Headroom Trolley for single-girder cranes and monorails; Double Girder Trolley for double-girder cranes lifting heavier loads (up to 100 tons); and Normal Headroom Trolley for monorails, restricted side clearances, or application with curved runways.
