Variable Frequency Drive Has Excellent Speed Regulation and Control Performance Rtg Crane

The rubber-tired gantry crane can realize a variety of modes such as straight travel, diagonal travel, horizontal travel, in-situ rotation, Ackerman steering, etc.It has mobility, flexibility, adaptability, high work efficiency, small size occupation area and do not need to lay the rail which are particularly suitable for beam factories with horizontal layout. The rubber Tired gantry crane can work independently or collaborative work by two units.The crane mainly consists of main beam, support leg, hoisting mechanism, tire walking and braking system, steering mechanism, power system, electrical system, hydraulic system, hydraulic transmission system, cab, control system, safety device, etc.The tire type container gantry crane(also known as yard/field bridge) is a specialized machinery used in large specialized container yards to load and unload standard containers. It is not only applicable to container terminal yards, but also to container dedicated yards.Equipped with diesel AC generator set for power supply and digital variable frequency speed regulation, it can move in two directions within the container yard. Equipped with telescopic slings capable of lifting 20 foot and 40 foot containers. In general, the span of the field bridge has been standardized to 23.47 meters (six lanes plus walkways), and non-standard span field bridges can also be supplied. The lifting height can ensure the lifting of a 40 foot high 9'6 "container, crossing four layers (or five to six layers) of the container stack.The traveling mechanism of the crane can be four-wheel or two wheel drive. To prevent collisions between yard bridges and between yard bridges and containers, a manual deviation correction system and anti collision devices at the four corners of the crane are installed.The mechanical operation of the small car can adopt rack and pinion type or dual axis or single axis drive, ensuring smooth operation. There is a cab under the small frame, where the driver operates the entire crane.Safety features:1.Automatic rectify deviation control 2.Weight overload protection device  3.Top quality polyurethane buffer  4.Phase protection  5.Lifting limit switch,cross traveling limit switch,long traveling limit switch6.

Audio and video alarm systemTire type beam hoist(also called beam handing machine) is used for beam handling in passenger dedicated lines, as well as in railway, highway, and urban light rail beam yards. The conveyor adopts a tire type walking system and is equipped with a steering system, which can achieve longitudinal, transverse, and curved walking when transporting beams, and the working surface can cover the entire beam field.This machine can be equipped with a double beam crane, and a single machine can handle various types of beams of 1000 tons or less; It can also be equipped with a single beam crane, with two handling machines working together to transport various types of beams weighing 1000 tons or less.Yacht Crane, also called boat hoist, is widely used in water sports club, sailing and voyage learning. Mobile boat hoist(MBH), Which can carry boat with different capacity(10t-1000t) out of water, is used for doing maintenance for boat or make new boat into water. Mobile boat hoist can put boat on the bank, so it is easy to do maintenance and repair for boats. This can greatly reduce the maintenance cost.The mobile boat hoist comprises a main structure, electric hydraulic driving system, traveling&steering system, lifting system, sling adjust system, electric control and safety protection system, wireless remote control and local control panel.parameters of RTG container gantry craneFollowing technical specification is for reference.Spreader is for container 20`, 40` and 45`.Capacity of Spreadert30.53540.5Working Duty A6A6A6SpanS23.4723.4723.47BaseB7.47.47.5Lifting HeightH15.415.418.2SpeedHoistingWith full loadm/min121223Only with spreader242446Traverse707070TravelingWith full load454545Only with spreader909090Main DimensionsL253702537025370H1220302233425134L1905905905L2950950975Total Power of Diesel MotorKW~305~305~400Total Power of GeneratorKVA~518~595~720Max. Working Load of WheelKN273287320  After-Sales ServiceOur after-sales service provide:1.14 months warranty when products leave the factory, or 12 months warranty after installation 2.
