Cranes are commonly used equipment in everyone's operations. After all, cranes can reduce a lot of effort for people's operations. However, when using cranes, there are often shaking phenomena. So, what is the reason for this phenomenon and how should we deal with it? Let the company's experts explain it in detail to you!
(1) Accelerating transmission parts are worn out (a basic type of component failure). The single beam crane has two operation modes: ground and air. There are two types of ground operation: wired handle operation and remote control handle operation; aerial operation refers to operation in the driver's cab. The driver’s cab has two types: open and closed. It can be divided into two types for installation on the left or right according to the actual situation. There are two types of entry directions: side and end to meet the needs of users. As the car body twists, the wheels on both sides rotate accordingly, so that the transmission parts of the car body are subjected to multiple repeated impacts, which accelerates the wear of the combined parts such as gears and keys (a basic type of component failure). Severe twisting also has the risk of twisting the drive shaft (composed of the drive shaft: shaft tube, telescopic sleeve and universal joint).
(2) Deform the bridge. Because one side of the bridge is leading at the same time, one side is lagging, and at the moment of rebound, the leading side is lagging, and the lagging side is leading. In this way, the front and back oscillates and twists, causing plastic deformation or cracking at the junction of the bridge and the beam.
(1) A certain wheel does not turn well. Because the backing plate of the fixed wheel bearing (bearing) seat is not right, the bearing (bearing) is not flexibly clamped, and the wheel stops first when parking.
(2) The wheel coupling key is loose.
(3) Wear (a basic type of component failure) clearance for transmission parts. For example, the gear of the gear coupling and the gear of the reducer and its combination key are loose, and the connecting bolt (composition: head and screw) of the transmission shaft (composition of the transmission shaft: shaft tube, telescopic sleeve and universal joint) (hinge Hole bolt (composition: head and screw)>The gap between the hole and the hole is worn out.
(4) For cranes that are driven separately, the parameters of the two motors are not matched, resulting in out of synchronization. The single beam crane has two operation modes: ground and air. There are two types of ground operation: wired handle operation and remote control handle operation; aerial operation refers to operation in the driver's cab. The driver’s cab has two types: open and closed. It can be divided into two types for installation on the left or right according to the actual situation. There are two types of entry directions: side and end to meet the needs of users. Single-girder cranes usually refer to single-girder bridge cranes. The main beams of single-beam crane bridges mostly use I-shaped steel or a combined section of steel and steel plates. The hoisting trolley is often assembled by chain hoists, electric hoists, or hoists as parts of the lifting mechanism.
(5) The braking torques of the brakes on both sides of the crane that are driven separately are inconsistent. When parking, one brake wheel has stopped, and the other is still rotating.
(6) The tightness of the two brakes (zhá) is too different.
The above is the cause and solution of the crane shaking accident that the company brought to you. The user needs to analyze the cause of the failure according to the specific situation, and eliminate it separately, and the shaking phenomenon can be solved.
