First of all, know the environment that your crane will be operating in. For the workshop, there is a workshop gantry crane. For port or dock, there is container gantry crane. For small service, we provide portable gantry crane.

Next, choose the right parameters that suit your actual situations, such as span length, lifting height, working duty, etc. Different applications require different dimensions. Thirdly, any special requirements for operation or installation. Everything will be easier for you when you understand all these things. If you are not certain what kind of a crane you need, contact us and we will give you reliable and professional instructions.

What Is The Delivery Time Of A 50 Ton Gantry Crane?
The delivery time of gantry crane is usually 20 to 40 working days. You can also purchase an electric hoist together, and the lead time of hoist is 15 days. Besides, if you need a specific customized crane, the delivery time will be longer. What’s more, crane is customized products and designed according to the different requirements of customers , so there is not in stock.
What Is Work Duty Of 50T Gantry Crane?
The work duty is determined by the load state and cycle times, not the higher the lifting weight is. That is, the more frequently a crane is used, the closer each lifting weight is to the rated lifting weight, the higher the work duty is.
How To Guarantee The Crane’s Life Span?

In order to ensure the corrosion resistance of the crane, we will perform the following treatments: First, for the steel plate of the crane, we will make shot blasting and spray epoxy zinc-rich primer painting after cutting.

Secondly, there will be base coat, middle coat, finish coat, three layers painting totally. All have high corrosion resistance, strong adhesion features, and a total thickness of 105 micron to ensure that it reaches the ISO standard derusting grade Sa2. Finally, we will design rain cover for motors, electrical appliances, and lifting parts to avoid the entry of rainwater.

What Are The Documents Aicrane Will Privide?

Documents: Crane instruction, certificate of qualification (including motor, reducer, brake, steel wire rope, hook group, drum group, wheel group, overload limiter, limiter, electrical components and crane, etc.), steel material testing list and crane maintenance manual;

What Are The Electrical Protection System Of Our Gantry Crane?
  • Short circuit protection: The main power circuit is set with automatic air switch, as the crane short circuit protection. The control loop is equipped with a small capacity automatic air switch for short circuit protection.
  • Voltage loss protection: The circuit structure has the function of voltage loss protection. When the power is restored after the power failure, the crane must press the start button to restart the operation, eliminating the possibility of self-operation of the crane when the power is on.
  • Emergency power off switch: The crane is equipped with red mushroom head type rotary reset emergency power off switch, which is used to quickly cut off the total power supply and control loop of the crane in emergency. The emergency power off switch is installed in a place convenient for personnel to operate.
  • Overload limiter: When the load reaches 90% of the rated lifting capacity, it will send out warning alarm signal. When the load reaches 110% of the rated lifting capacity, it will immediately cut off the lifting power supply and send out restraining alarm signal. The sensor of overload limiter has the characteristics of moisture-proof and earthquake-resistant, and the sensor is connected with the control box to reduce the interference of the sensor signal.
  • Phase break, wrong phase, over voltage, under voltage protection: The integrated protector in the crane circuit system has the protection function of phase break, wrong phase, over voltage, under voltage, the above four cases will automatically cut off the total power supply of the crane, to prevent personnel injury and equipment damage.
What Are The Tips On The Safe Operation Of Gantry Crane 50 Ton?
  • Operators need to learn the manual and be trained enough before operating a 50 ton gantry crane.
