The folding engine crane is mainly composed of base, column, telescopic arm, hook and hydraulic system. The base is usually wider to ensure the stability of the crane when it is working. Column is the main supporting structure of folding engine crane, and its angle can be adjusted to adapt to different working environments. The telescopic boom can be extended and retracted through the hydraulic system, thus changing the working radius of the folding engine crane, and its end is equipped with a hook for hanging heavy objects such as engines.
Its folding function is mainly embodied in the foldable design of the column and telescopic arm. When not in use, by folding these parts, the floor space of the crane can be greatly reduced, which is convenient for storage and transportation.
Working Principle of Folding Engine Crane
Power is provided by hydraulic system. When the handle of the hydraulic pump is operated, the hydraulic oil is pressed into the hydraulic cylinder to push the piston to move. For the telescopic arm, the piston of the hydraulic cylinder pushes the telescopic arm to extend or retract; For the lifting function, the hydraulic system makes the hook rise or fall, so as to lift and move the heavy objects such as the engine. Its working principle follows Pascal's law, that is, the pressure exerted on the liquid can be transmitted in all directions without change.
How to Use an Engine Support Bar
Different types of engines use engine brace bars in different ways. The following are two common types:
Hood Engine Brace Bar
Open the hood: first find the hood switch in the car, usually located in the driver's door or under the instrument panel, and pull the switch up to unlock the hood. Then go to the front of the car, reach in through the gap in the front of the hood, find the lock of the hood and pull it to open the hood.
Installation of engine brace bar: generally, there are corresponding support points on the lower part of the hood and the frame of the car body, and one end of the engine brace bar is fixed on the support point of the car body, and the other end is fixed on the support point of the hood. Some engine brace bars may need to be pressed or rotated by a certain angle to be completely locked, so as to ensure that the engine brace bars are completely locked to prevent accidental falling.
Check the stability: After installation, gently shake the hood to ensure that the engine brace bar is firm and can support the hood stably.
Close the hood: After completing the maintenance, first remove the engine brace bar and carefully close the hood to ensure that it is completely locked. If it is a hydraulic engine brace bar, first close the hood to the maximum open position, and then press the engine brace bar back to its original position.
Engine Bay Support Bars
Preparation: park the vehicle on a flat and solid ground, pull the handbrake, start the engine, let it run for a period of time, and then turn it off, so that the engine is in a warm-up state for subsequent operation. At the same time, prepare the necessary tools, such as wrenches and sleeves.
Determine the support point: open the engine compartment cover and find the appropriate support point on the engine and the corresponding fixed point on the vehicle chassis or frame according to the vehicle maintenance manual or actual situation. These support points are usually solid parts designed to ensure that the weight of the engine can be safely supported.
Install the engine brace bar: connect one end of the engine brace bar with the supporting point of the engine, and generally fix it by bolts, nuts or special fixtures to ensure firm connection. Then connect the other end of the engine brace bar with the fixed point on the chassis or frame and fix it. During the connection, it may be necessary to adjust the length and angle of the engine brace bar so that it can be installed in place accurately.
Inspection and adjustment: After the installation is completed, check whether the engine brace bar is firmly installed, and whether it is loose or abnormal. You can rock the engine gently, observe whether the engine brace bar can support the engine stably, and make further adjustments and fastening if necessary.
Dismantle the engine brace bar: After the engine is repaired or maintained, disassemble the engine brace bar in the reverse order of installation. Loosen the fixed points on the chassis or frame first, then loosen the connection points on the engine, and take down the engine brace bar and keep it properly.
