Most installation problems are decided months earlier, on the drawing and on site. Here is what to have ready, in order, so the crane is working the week it arrives.
1. The runway comes first — and it is your scope
We supply the crane, the rail clips, end stops and clamps. The runway beams, the columns that carry them and the rail foundation are local work, built to our drawing. Before anything is fabricated, you need three numbers from us and one check from your engineer:
- Wheel load per corner at rated load — the load the runway and columns must take
- Wheel base — the distance between the wheels along the direction of travel
- Rail section, gauge and level tolerance — how straight and how level the two rails must be
- The clearance envelope — how much space the crane needs above and beside it
The most common cause of a crane that runs badly for years is a runway that is out of level or out of parallel. It is cheap to get right the first time and expensive to correct later.
2. Power supply and the panel position
Confirm the site voltage and frequency — 380 V/50 Hz is standard in Vietnam and much of Southeast Asia, but 415 V/50 Hz and 440 V/60 Hz occur — and whether the supply is stable or from a generator. Tell us before the order: the panel and drives are built for it, and correcting a voltage mismatch on site means new components.
Decide where the crane's main isolator and panel will be, how the power gets to the runway (cable, festoon or busbar) and who is responsible for that cable. It is a small line in the quotation and a large argument on site if nobody owns it.
3. Access: the crane has to get in
A 30 m bridge does not go through a 3 m door. Plan the route in advance: the door the crane arrives through, the space to lay out girders and end carriages, the lifting equipment available, and whether the mobile crane can reach the bay from outside. If the route is tight, the shipping split has to be decided at the order stage — not after the container has been loaded.
4. The load test and handover
Before handover, the crane should be load tested — normally at rated capacity, and at 1.25× where specified — with the overload limiter set and demonstrated, the brakes checked, and both hoist limiters tested. Some sites require the test in the presence of an inspector; tell us early so the documentation matches what your inspector expects.
Handover should include a walk-through of the maintenance schedule with the person who will actually maintain the crane, and the manual handed to them — not filed in an office. If we provide a supervisor, that is part of what they are there for. Our workshop crane page covers the sizing side; this list is the site side.
The short version
Ready before the crane ships: runway designed against our wheel loads, rails level and parallel, power supply confirmed and routed, access route checked with door dimensions, and an erection team with lifting equipment arranged. Do those five things and installation is measured in days. Skip one and the crane sits in your yard while people argue about whose scope it was. Send us your site details and we will mark up what goes where.
