升降机整机都属于免维护的轴承，所以在使用的过程中，只要做定期的升降测试即可，并不需要做一些维护和保养的工作，因此容易忽略它也有磨损的部件。由于升降机长时间在地面行驶，会让轮子产生磨损，如果磨损严重而没有及时的更换则会造成设备的推拉困难。
Lifts lift machine manufacturers introduced belong maintenance-free bearings, so the use of the process, as long as you can do regular lifting test does not need to do some maintenance and repair work, it is easy to overlook it has worn parts. Due to lift a long time traveling in the ground, the wheels will be worn, if badly worn without timely replacement of the equipment will cause difficulty sliding.

升降机轮子也分很多种，有尼龙轮、PU轮、聚氨酯包尼龙、橡胶轮、电木伦等。大多数手动搬运车配备尼龙轮，是因为市场普遍、价格便宜，但是磨损度较差，行走起来噪声也大。在整个搬运过程中起着不可替代的作用，在使用当中我们一定要注意保养，这样才能使我们的工作效率大大的提高，因此脚轮要定期保养是必不可少的。
Lift manufacturers to remind you lift the wheels for very many, nylon wheel, PU wheel, polyurethane nylon bag, rubber wheel, bakelite Lun. Most manual handling car is equipped with nylon wheel, because the market generally, cheap, but the degree of wear less, walking up the noise is also large. Throughout the handling process plays an irreplaceable role in the use of which we must pay attention to maintenance, so as to make our work efficiency is greatly improved,and therefore casters want regular maintenance is essential.

建议在使用的过程中，要经常的看一下轮子的磨损情况，要防止轮子里面转入一些杂物。如果轴承不灵活要及时的进行润滑，不要硬拉硬推，防止轮子卡死在地面直接移动。定期加润滑油，脚轮和活动轴承就能长期使用。把润滑脂涂于轮轴、密封圈内和滚柱轴承的磨擦部位，能减少磨擦并令转动更灵活，正常情况下每六个月进行一次润滑。
Lift manufacturer recommends use of the process, we should always look at the wear of the wheel to prevent wheel inside into some debris. If the bearing is not flexible to be timely for lubrication, not to deadlift a hard push to prevent the wheels stuck in the ground to move directly. Regular lubricating bearing casters and activities can be long-term use. Apply grease to the axle, friction parts inside seals and roller bearings, can reduce friction and make the rotation more flexible, under normal circumstances lubricated every six months.
