Single beam gantry crane structure
1. Lifting weight limiter: When the actual lifting weight exceeds 90% to 95% of the rated lifting weight, the lifting weight limiter sends an alarm signal. When the actual lifting weight is between 100% and 110% of the rated lifting weight, the lifting power source is automatically cut off. , allowing items to drop.
2. Lifting height limiter: When the object pickup device rises to the designed lifting height, it should be able to automatically cut off the power source for lifting.
3. Single beam gantry crane manufacturer operation stroke limiter: The crane trolley and trolley automatically cut off the power source in the forward direction when they reach the limit position specified by the design.

4. Buffers and buffer devices: Buffers or buffer devices can be installed on the sevencrane single beam gantry crane factory or on the track end stop device.
5. Wind-resistant and anti-skid devices: There are three main types of wind-resistant and anti-skid devices for cranes, namely rail clamps, anchoring devices and iron shoes.
6. Anemometer and wind speed alarm device: The anemometer should be installed on the upper part of the crane facing the wind. When the wind force is greater than the wind speed set value calculated in the working state, it should be able to send out an alarm signal.
7.Safety devices with special requirements:
(1) Anti-collision device: When two or more cranes are working on the same track, anti-collision devices should also be installed.
(2) Track cleaning device: When materials may accumulate on the track and become an obstacle to the operation, a track cleaning device should be installed under the cart frame to clean the obstacles. The distance between the cleaning device and the rail top should be maintained at 5mm.
8. Track travel limit switch: The travel switch is also called a limit switch or a position switch. It is a control appliance that switches the working state of the circuit according to the stroke position of the moving parts. The action principle of the travel switch is similar to that of the control button. In mechanical equipment, the travel switch is installed at a certain travel position in advance according to the process requirements. When the component is in operation, the impact block is installed on it to press down the travel switch ejector to make the travel The contact action of the switch realizes the switching of the circuit and achieves the purpose of controlling the stroke position of the moving parts. Commonly used are mechanical travel switches and infrared travel limit switches.
