SSY004911131 1250 Cab Assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

SSY004911131 is a SANY original part number for the cab assembly, integrating a reinforced rollover/falling object protection frame, an ultra-quiet sealed cabin, a 10-inch color touch screen smart terminal, a multi-directional electrically heated air suspension seat, a fully automatic constant temperature air conditioner, a 360° panoramic imaging + sound and light warning system, and a rear window emergency escape exit. It is the core human-machine interface unit connecting the operator with the machine’s power/hydraulic/electrical systems. It is mainly used in large open-pit coal mines and metal mines for mining and topsoil stripping operations. Through the integrated design of high-strength structure + silent sealing + intelligent electronic control, it achieves high safety, low noise, and easy operation performance, avoiding personal injury caused by insufficient cab protection and misoperation caused by noise fatigue. It is suitable for mining conditions with high temperature, high dust, large temperature difference, and strong vibration, and is a key original part for ensuring personnel safety, improving work efficiency, and reducing downtime losses in mines.

Core technical parameters

Model: SSY004911131
Main body material: The cab frame is made of Q550 high-strength steel welded as a whole and reinforced with cold-formed steel; the front/side windows are reinforced light-colored bulletproof safety glass with wipers and washer; the shock absorption system uses silicone rubber shock absorbers, which isolate more than 90% of the machine’s operating vibration; the welds have undergone non-destructive testing, and the overall rigidity meets the international standards of ISO 3471 (ROPS) and ISO 3449 (FOPS Level II), with an impact energy of ≥200kJ.
Operating temperature: -30℃ to 55℃. In low-temperature environments, the glass heating and seat heating systems start quickly; in high-temperature environments, the fully automatic air conditioning system cools down rapidly.
Structural Design: Ultra-quiet frame structure with high-density sound and heat insulation cotton inside the skeleton, covered with wear-resistant and anti-aging panels; openable left-side window and rear window emergency escape exit, combining ventilation and emergency response; multiple sets of high-strength bolts for easy installation and disassembly; integrated wiring harness channel and hydraulic pipeline interface to avoid exposed pipeline wear; equipped with grab handles and anti-slip walkway to improve safety when getting on and off the vehicle; rearview mirrors adopt a wide-angle + blind spot filling design, combined with 360° panoramic imaging to eliminate blind spots during operation.
Shape and Dimensions: The overall design features a streamlined, box-like structure, adaptable to the SY1250H cab space; the interior operating space is spacious; the mounting base dimensions are identical to the slewing platform cab base, allowing for direct factory replacement; the glass area is large.
Surface treatment: The frame surface is protected by three layers of shot blasting, epoxy primer and weather-resistant topcoat. The coating thickness is ≥100μm, the adhesion reaches GB/T 9286 level 1, and the salt spray resistance is ≥800 hours. It can resist acid rain and high dust corrosion in mines; the glass surface is treated with anti-glare; the interior panels are made of wear-resistant and waterproof material, which is easy to clean and maintain.

Core functions and roles

As a “mobile safety fortress” and “intelligent command center” for 100-ton mining excavators, its core function is to provide operators with a living space that meets international safety standards, isolating them from the harsh mining environment (dust, noise, vibration, falling objects). Simultaneously, through intelligent touch terminals and control systems, it precisely issues work instructions, enabling smooth start-up and shutdown, action switching, and micro-operation control of the entire machine. In scenarios such as large open-pit mines and water conservancy projects, its FOPS/ROPS dual-protection structure resists falling rocks and side-tipping impacts; its ultra-quiet sealing design reduces cabin noise to below 73dB, alleviating fatigue during long-term operation; its air-suspended seat and constant-temperature air conditioning enhance operational comfort; its 360° panoramic imaging and sound and light warning system reduce operational risks; and its precise installation interface ensures coordinated operation with the slewing platform and slewing device, making it one of the decisive components for the overall safety performance and operational efficiency of the machine.

Applicable Scenarios

Widely used in ore mining and topsoil stripping operations in large open-pit coal mines and metal mines, it is also suitable for large-scale water conservancy projects, port and wharf construction, and large-scale urban demolition and backfilling projects. It is particularly suitable for 24-hour continuous heavy-duty operations and harsh working conditions (high dust, strong impact, large temperature differences between day and night, and strong vibration), making it a core original equipment manufacturer (OEM) structural component for large-scale mining and the timely progress of large-scale projects. It is also compatible with commercial scenarios such as equipment overhauls, old machine upgrades, and replacement of accident vehicle cabs. Its precise OEM compatibility and high reliability can significantly reduce modification costs and downtime, improving the return on investment for projects.
