The wiper device 10 is respectively arranged on the fixing plates 2 on both sides of the cab, the fixing plate 2 on the top side of the cab, and the top frame on the front side of the cab, for cleaning the outer surface of the tempered glass 4 on each side;

[0042] By concentrating the tempered glass 4 on the front side of the driver's cab and the adjacent area and controlling the proportion of the glass area on each side, an optimal balance is achieved between maximizing the field of view and structural strength; the innovative layout of the four-sided wiper device 10 can effectively remove pollutants such as seawater spray and rainwater from the outer surface of the glass, solving the problem of blurred side vision caused by the traditional design of only arranging wipers on the front window, ensuring the safety and convenience of operation; it can significantly reduce operational errors caused by limited field of view, improve the long-term service life of the driver's cab, and reduce maintenance workload.

[0051] The thickness of the fixing plate 2 is 30-50 mm. The driver's cab is soft-packed, comprising a sponge layer and black perforated flame-retardant imitation leather attached to the sponge layer. The ratio of the sponge layer thickness to the imitation leather thickness is 25:1.

[0052] The thickness of the fixed plate 2 is designed to be 30-50mm, and the driver's cab is soft-packed, which increases the driver's comfort while ensuring the stability of the cab; the combination of sponge layer and imitation leather not only effectively absorbs noise and improves the quietness in the cab, but also prevents fatigue caused by long-term work; the flame retardant properties of the imitation leather material increase indoor safety and reduce the threat to the driver from emergencies such as fire; the selection of soft-pack materials not only improves the driver's work comfort, but also ensures the durability and safety of the cab under high-intensity use.

[0053] The ratio of the thickness of the aluminum plate 7 to the thickness of the insulating rubber carpet 8 is 4:3; the insulating rubber carpet 8 is composed of the following components in percentage by weight:

[0054] Natural rubber: 45-50%;

[0055] Styrene butadiene rubber: 18-22%;

[0056] Precipitated silica: 12-15%;

[0057] Clay: 5-6%;

[0058] Aluminum hydroxide: 8-10%;

[0059] Zinc borate: 2-3%;

[0060] DCP peroxide: 3-4%;

[0061] TAIC co-crosslinking agent: 1-2%;

[0062] Amine antioxidant + paraffin: 3-4%;

[0063] The ratio of natural rubber to styrene-butadiene rubber is 2-2.8:1; the ratio of precipitated silica to pottery clay is 2-3:1; the ratio of aluminum hydroxide to zinc borate is 2.7-5:1;

[0064] The combination of the aluminum plate 7 and the insulating rubber carpet 8 effectively improves the shockproof and wear-resistant properties of the floor. At the same time, the insulating function of the rubber carpet can prevent accidents to electrical equipment or lines, ensuring the safety of operators. The material of the insulating rubber carpet 8 is blended according to a specific proportion, which increases its durability and anti-aging ability, and can maintain good performance during long-term use. By rationally blending the material composition, the anti-slip properties and comfort of the carpet are improved, further enhancing the operator's working experience in the driver's cab.

[0065] A removable guardrail is installed on the front side of the driver's cab; the top of the driver's cab is inclined at an angle of 10-15 degrees; an anemometer 12 is installed on the top of the driver's cab; in addition, a radio antenna 11 is installed on the top of the driver's cab, and a radio connected to the radio antenna 11 for receiving signals is installed in the driver's cab; in addition, the driver's cab is also equipped with air conditioning to increase comfort;

[0066] The detachable guardrail enhances the safety of the operator's cab, providing additional protection in harsh environments or extreme weather. The tilted design optimizes aerodynamic performance while facilitating the natural shedding of rainwater. The anemometer 12 not only helps operators monitor environmental changes in real time, but also provides necessary reference data for crane operation, ensuring stable operation of the equipment under varying wind speeds.

[0067] All wiring in the driver's cab is done in a concealed manner, which includes the formation of a cable channel. The cable channel is formed by a groove built into the driver's cab frame 1, and the cables are led from the groove to the main console;

[0068] By adopting a concealed wiring method, all cables and lines are cleverly hidden in built-in troughs, making the lines safer and avoiding damage to the cables from the external environment; the hidden cable method not only optimizes the spatial layout in the driver's cab, but also makes the visual effect in the driver's cab neater, reducing the safety hazards that may be caused by exposed cables; this design makes equipment maintenance and inspection work easier, effectively improving the long-term use efficiency and reliability of the equipment.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
