Description

Technical Field

[0001] The utility model relates to the technical field of forklift cabs, in particular to a cab for a cold storage forklift. Background Art

[0002] Domestic cold chain logistics is developing rapidly, and the capacity of cold storage is increasing rapidly. The most common cold storages on the market are -18℃~-30℃ freezers, and even lower -60℃ ultra-low temperature cold storages. The transportation of goods stored in cold storage requires a professional cold storage electric forklift. Due to the huge temperature difference between the cold storage and the natural environment, the high ambient temperature, and the moisture in the air, when the cold storage forklift leaves the warehouse, all the windows of the conventional cab will quickly frost and ice within one second. The frost cannot be removed by wipers, which affects the forklift driver's vision. If the forklift continues to be driven at this time, there will be major safety hazards.

[0003] The existing technical means, whether using a heater or using silver paste to electrically heat the glass, cannot solve the problem of instant frost and ice on the glass when the forklift leaves the cold storage. Since the ice on the glass will affect the driver's vision when operating the forklift, there is a safety hazard. Therefore, most cold storage forklifts are not equipped with a cab at present. The driver is very uncomfortable working in the cold storage and can only work for a short time wearing cold-proof clothing. Therefore, a cab for a cold storage forklift is proposed.
