3.5-Ton lithium-ion forklift full load climbing performance, reference data for factory ramp operation

In the transshipment of factory warehoused goods, ramp traffic is a common scenario. The 3.5-ton electric counterweight lithium-ion forklift is the main model, and its fully loaded climbing performance is the core concern of many users.

Interpret the standard full-load climbing conditions of 3.5-ton lithium-ion forklift. In the safety and performance test of general industrial vehicles, there are clear conditions for the measurement of the rated full-load climbing degree, such as requiring that the surface of the test ramp is dry and flat without oil pollution, the tire pressure conforms to the provisions of the vehicle instruction manual, the environment is in the normal temperature and pressure range, the vehicle is in good maintenance condition and the load is evenly placed in the center of the rated load, etc.

Reference for core performance parameters of full-load climbing of 3.5-ton lithium-ion forklifts. For 3.5-ton electric balance heavy-duty lithium-ion forklifts in compliance on the market, the rated full-load climbing degree is usually between 15% and 20%, which is converted into a commonly used geometric angle of about 8.5 degrees to 11.3 degrees. At this rated slope, the vehicle needs to start smoothly and without slippage. The speed during stable driving is generally controlled at about 3 kilometers per hour. The parking brake function needs to be able to reliably lock the vehicle and prevent sliding.

The practical operation reference details of the ramp operation in the factory area. First of all, the ramp with surface conditions close to the test standards should be selected first, and the ramp with slippery, snow or oil stains and serious damage should be avoided. Second, check the vehicle status before operation, adjust the appropriate load position, and ensure that the lift height of the fork does not exceed the reasonable range of field of view occlusion. When driving, choose the appropriate power adaptation mode according to the functions equipped with the model, reduce the speed in advance when going uphill, and maintain a uniform speed. It is strictly forbidden to slide in neutral when going downhill. It can be used in conjunction with the power slow down function and foot brake to control the speed. When parking for a long time, tighten the handbrake, put down the fork about 10 to 15 cm to touch the ground, and pad the triangle wood under the wheel.

Common factors affecting the full-load climbing performance of 3.5-ton lithium-ion forklifts. In addition to the environment and vehicle conditions outside the test standards, the offset of the center of gravity of the cargo, excessive tire wear, and low ambient temperature will also have certain effects. For example, low temperatures in winter may temporarily reduce the discharge efficiency of lithium batteries. At this time, long-term heavy-duty operations on ramps close to the rated slope should be avoided.
