overhead bridge cranes

grab bridge crane control system during handling, installation, wiring, what precautions have
Digital Intelligent crane control system JH-DSC Before installing and commissioning the control system, be sure to familiarize themselves with the safety precautions and in strict accordance with the requirements of handling, installation, commissioning and maintenance.
JH-DSC handling
Please hold the JH-DSC bottom when handling, otherwise it will be dangerous shedding.
JH-DSC installation
JH-DSC damaged and missing parts of the JH-DSC, please do not install and use, to avoid lead to accidents.bridge gantry cranePlease install on a non-combustible materials such as metal, and can withstand the weight of the place, otherwise there will be people injured when falling.
Please try not to JH-DSC installation of water splashing in place, it may cause a short circuit JH-DSC.
Do not JH-DSC installed in direct sunlight, otherwise it will shorten the life of JH-DSC.
Wiring must be carried out by qualified personnel, otherwise there is the risk of electric shock.
Mains are completely disconnected, and then wiring, otherwise careful of electric shock.
JH-DSC must be grounded ground terminal, otherwise the risk of electric shock.
Before power must cover the cover, otherwise it will lead to electric shock or short circuit.
Do not confuse the input and output terminals, otherwise JH-DSC explosion hazard.
Energized, do not touch the JH-DSC terminal, non-wet hands to avoid electric shock.
Please correct the connection between the output terminals and the motor cable U, V, W, on the contrary will affect the direction of rotation of the motor.

overhead gantry cranes Machinery Management System

In order to strengthen the management of lifting machinery, lifting machinery to ensure the normal operation and safety, the system is formulated.gantry crane manufacturers1. The management system is applicable to overhead cranes, gantry cranes, crane (tower) cranes, gantry cranes, truck cranes, tire cranes, crawler cranes, cargo lift, hoist, electric hoist. Does not apply to railway cranes, lifting equipment underground mines, manned lifting equipment.container gantry crane2. The business should be based on the type, number and complexity of lifting machinery, the establishment of full-time or part-time engineering and technical personnel responsible for the management of mechanical lifting device power management.
3. Use the unit should establish the necessary lifting equipment repair and maintenance, periodic inspection, rules and regulations, safe procedures and shift system.4. lifting equipment must be registered and established by one device files. Files should include the original technical information product certification, quality certificates, drawings, etc., as well as running records, previous technical inspection reports, overhaul, change the original design performance and major accident records.
5. A variety of different specifications of lifting machinery must press GB6067-85 "crane safety regulations," the provisions of the appropriate safety devices installed, tower cranes to add enough weight. Various rope selection, use and disposal procedures must also comply with the requirements.
6. lifting machinery workplace have adequate lighting and lifting channel, and should be kept a safe distance from the provisions of the nearby equipment, buildings, and electrical lines.
7. lifting machinery to implement dedicated system, each person responsible for lifting machinery must use management.
8. The operator of lifting machinery used must be "four three will understand" (understand performance, understand the structure, to understand the principles, understand the purpose, use, maintenance will be, will be troubleshooting). And specialized training, after obtaining the certificate by the department exam before being fully operational.
9. When the newly acquired lifting machinery, manufacturing must obtain a permit to purchase a professional manufacturer of products, safety protection devices to be complete. And a complete certificate.
10. When using the unit for a major transformation of lifting machinery or alter the original design performance, must come up with based on "crane design specifications" transformation plan, design drawings, books and quality assurance measures calculated and the competent authorities and by the factory director or Chief Engineer approval, the local labor department.
11. Use the units should be regularly lifting machinery for technical inspection and testing, periodic inspection and testing of the content performed in GB6067085 "crane safety regulations" requirement.
12. The new installation, after overhaul or change the original design performance of lifting equipment must be static load test and dynamic load testing and other technical inspection before use, the device power management, security services and user departments to identify common acceptance, and before use by the competent director or chief engineer approval.
