Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.

Vibration aging treatment and effect judgment: According to the aging process plan, after setting the support points and vibration pickup points of the workpiece, use a rigid fixture to fix the exciter on the workpiece, and use the manual function of the equipment to test the vibration. It is determined that around 5300 revolutions is the resonance frequency of the component. The amplitude generated by the eccentric gear of the exciter in the fourth gear can meet the vibration processing requirements of the foundation seat, so the excitation force is selected as the fourth gear.

Professional elevator manufacturers are safe, environmentally friendly, and economical! Our products are exported to foreign countries and highly trusted

Outbound call form: Outbound call boxes are pre embedded or installed in a column style on the wall or ground near the parking floor above and below the platform, and are linked to operate the platform up and down.

.Emergency stop: Press the emergency button switch to raise or lower the machine.

The lifting foundation of the platform is a large structural component made of alloy steel plates with different thicknesses that are welded together. The welding amount is large the structural shape is complex, and residual stress is inevitably generated during the manufacturing process. In order to prevent deformation of the components due to changes in residual stress during use it is necessary to perform stress relief treatment on the completed components.

Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.

According to calculations, when the support points of the beam type components are located along the length of 1/9L on both sides,AlexandriaMobile boarding bridge, the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component, and the structure is complex. Therefore, two support points should be taken on each side for time treatment.

Good quality.When the lifting base plate descends, the safety net below immediately stops running and descends when encountering obstacles.

The design of support points for selecting process parameters is to avoid energy consumption and noise generation due to collision between components and supports during vibration. The supports should be arranged near the nodal line, and the layout principle is: when the aspect ratio of the component is greater than 2, two point supports can be used; When the aspect ratio is close to 1, it is advisable to use or 4-point support.

02 The lifting platform adopts a fully hydraulic lifting mechanism,AlexandriaFully self-propelled lifting platform, which can be operated inside the platform bucket and on the elevator body. 03 The working arm of the lifting platform can rotate 360 degrees. 04 The hydraulic system is equipped with a safety valve to prevent the main arm oil cylinder oil pipe from cracking. 05 The hydraulic legs are equipped with a hydraulic locking device to prevent the leg oil cylinder from retracting. 06 The hydraulic system is equipped with an automatic platform overload protection device, In order to ensure the safety of operators, each section of the working arm on the platform 07 is equipped with safety limit devices. The hydraulic system seals on the platform 08 are all well-known domestic and foreign brands, and the power of the entire vehicle 09 is a diesel engine with its own power supply. The power supply can also be used. The hydraulic lifting platform is equipped with an emergency lowering device in case of power outage. The 11 folding arm lifting platform product can also use a 50Hz 380V power motor, and diesel engine dual power.

Firstly, it is necessary to start from the source. The current technology is relatively advanced. When manufacturing aluminum alloy lifting platforms, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now, nickel, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.

Create brilliance.The selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude, and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component, and the resonance frequency should be used to handle time dependent vibration. However, there may be one or more resonance peaks in large components, and using resonance peaks with higher peaks and lower frequencies for aging can achieve optimal results. The resonance frequency needs to be determined by trial vibration, which slowly increases the speed of the excitation motor from 0, and determines the relationship curve between the amplitude of the workpiece and the motor speed to determine the resonance point of the workpiece. According to the scanning curve, a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.
