罐笼可以全部用铝合金制成,面上涂有三层特制的油漆,此种罐笼的形式虽与现在我们矿山上所用的罐笼并没有什么区别但却有着下面的几个特点: (1)重量轻(其重量较同型态的铁罐笼的重量的一半还小),坚牢,不易腐蚀。 (2)修理费及所需电力减少。 (3)由于重量减轻使载重及捲扬速度均可加大,提高了罐笼的运输能力。 (4)捲扬机的捲扬深度可以增加,同时可以节省很大的传动装置。 Cages can all be made of aluminum alloy coated with three layers of special paint. Although not particularly different from the cages currently used in our mines, these cages have the following features: (1) light weight (Its weight is less than half the weight of the same type of canister cage), fast, not easy to corrode. (2) Repair costs and reduced power requirements. (3) As the weight is reduced so that the load and hoisting speed can be increased, improve the transport capacity of the cage. (4) winch winch depth can be increased at the same time can save a lot of gear.
