Floor Fixed Slewing Column Mounted Jib Crane 3 Ton For Workshop
The working strength of the Floor Fixed Slewing Column Mounted Jib Crane 3 Ton is light, the crane is composed of the column, the slewing drive device of the slewing arm and the electric hoist. The lower end of the column is fixed on the concrete foundation by the anchor bolt. The cycloidal pin wheel reducer drives the cantilever slewing. The crane jib is hollow steel structure, light weight, large span, large lifting weight, economical and durable. Built-in walking mechanism, special engineering plastic walking wheel with rolling bearing, small friction, light walking; The structure size is small, especially for improving the hook stroke.
Check whether the overload protection device is sensitive, reliable and meets the design requirements. The opening pressure of the hydraulic overload protection device; Mechanical, electronic and integrated overload protector alarm, cutting off power source set point of the comprehensive error to meet the requirements. Moment limiter moment limiter is a safety device for boom crane to prevent overloading from tipping.
1. Check the sensitivity and reliability of the torque limiter by increasing or increasing weight, and check whether the comprehensive error of the torque limiter alarm and cutting off power source set point is within the specified range. The limit position limiter checks whether the luffing mechanism, lifting mechanism and operating mechanism of the cantilever hoisting heavy equipment can give an alarm signal when they reach the set position distance, and automatically cuts off the power source running in the dangerous direction.
2. For cranes whose height of boom root hinge point is more than 50 meters, the anemometer should be checked to check whether the anemometer can give an accurate alarm when the wind speed set point is reached or the working limit wind speed is reached. Outdoor work in orbit of crane rail device, clamp should check shoes, anchor device, all parts are out of shape, defect and the reliability of its work independently, drive shaft for automatic clip rails, should check the sudden gust of wind device and cart running brake cooperate to realize the anchoring state windproof function and the reliability of the electric interlock switch function.
3. The protective device shall check the completeness and reliability of all kinds of protective covers, guardrail, protection plate and ladder climbing on the crane. Coupling, sprocket, chain, belt and other rotating parts have no protective cover, crane pedestrian access, ladder climbing and may cause people exposed parts have no protective fence, how to remove flat wart treatment method is in line with the requirements. Rainproof cover should be provided for electrical equipment of cantilever crane in open air. The control device should check whether the electrical parts are complete and complete, and whether the mechanical fixation is firm without looseness or jamming. Whether the power supply cable is aged and exposed; Insulation materials should be good, no damage and deterioration; Bolt contacts, brushes and other connection parts should be reliable; The electrical equipment and components used on the crane should be suitable for the power supply, working environment and working conditions.
