从 PortMiami 出来，超限货走不了隧道
PortMiami 隧道对超限货和挂标牌的 hazmat 关闭，所以一只超限箱得走 Port Boulevard 出港，穿过 Biscayne，从迈阿密市区里过。 隧道口之前设有超高检测和掉头匝道，所以过高的车会在到达洞口之前就被拦下、改走大桥，而不是到了跟前才发现。
在货动之前就知道这件事，决定了这是一趟规划好的运输，还是一辆停在隧道口的卡车。这也是我们为什么在报价之前而不是之后就问尺寸。
太重和太大，是两个不同的问题
超重是重量问题。一只跑重货的箱子需要三轴或者四轴底盘车，外加一张许可，而且各港口在州的限值之外还有自己的限值，但它骨子里仍然是一趟普通的集装箱运输。
超限是形状问题，它会换掉挂车。先是标准平板车，货太高就换 step deck 凹板车，再高到 step deck 也压不住合法高度，就上低平板车或者 RGN。一票货可以同时是这两样，而且两者分开计价，因为它们是分开解决的。

What happens to an over-height truck at the PortMiami Tunnel?
It gets caught before the portal. An over-height detector and a turnaround ramp sit ahead of the tunnel entrance, so a truck that is too tall is sent back to the bridge rather than finding out at the tunnel mouth. The tunnel is closed to oversized loads and to placarded hazmat either way, so an over-dimensional box leaves the port over Port Boulevard, across Biscayne and through downtown Miami. Knowing that before the load moves is the difference between a routed job and a truck parked at a portal.
What is the difference between overweight and over-dimensional?
Overweight is a weight question and over-dimensional is a shape question. They are solved separately, which is why they are priced separately. A container running heavy needs a tri-axle or quad chassis and a permit, and the ports carry their own limits on top of the state's, but underneath it is still an ordinary container move. An over-dimensional piece changes the trailer instead: a standard flatbed until it is too tall, then a step deck, then a lowboy or an RGN when even a step deck will not keep it legal. A load can be both at once.
What is the legal height limit for a truck in Florida?
13 feet 6 inches, and that single number decides more heavy haul questions than anything else. It sets where a standard flatbed stops working and a step deck or a lowboy starts, because deck height is the lever: a lower deck buys cargo height. Anything above the limit needs a permit and a surveyed route, since the permit says what you may move on the road and says nothing at all about the bridges, the wires and the tunnels that are actually in the way of it.
What do you need to quote a heavy haul move?
Dimensions and weight before anything else, which is why they get asked for before the quote rather than after. Length, width, height and gross weight decide the trailer, the permit, whether escorts are needed and which route is legal. Add the pickup and delivery points, whether either end has a crane or a forklift, and whether the piece has lifting points. A description is not enough on its own: two pieces that sound identical on paper can be a plain flatbed lane and a permitted, escorted job.
Can an overweight container move without transloading?
Yes, on a tri-axle or quad chassis and under a permit, with the port's own weight limits applying on top of the state's. Whether it should is the separate question. Transloading splits the contents across legal truckloads, takes the permit out of the inland leg entirely, and gets the container back to the line early so per diem stops. For a short local delivery the permit route is usually simpler and cheaper. For a long run the transload usually wins, and by a wide margin.

一份拖车报价里到底包含什么？
运输本身，加上那些事后最容易让人措手不及的附加费：底盘车、提前提箱、滞箱费、滞港费、车辆滞留费和仓储费。我们宁可一开始就把它们说清楚，也不愿意事后加到账单上。
