Crane Track Chocks
HPS Fabrications builds steel chocks that lock tracked dock cranes in position. The chock slides between the tracks, an operator steps on it, and it spreads and locks so the machine cannot creep. It is a small part with a serious job, and we build it as a regular repeat run rather than a one-off, which is the kind of production work we want more of.

A small part with a serious job
Shipyards move loads at the dock with small tracked cranes. A tracked machine on a hard surface will creep under load, and a creeping crane during a lift is a problem with no good ending.
The chock is the answer. It slides between the tracks, the operator steps on it, and it spreads and locks the tracks in place.
Designed around one machine
It looks like a wedge. It is not a generic wedge.
The geometry is engineered around a specific track profile, because a chock that nearly fits is worse than none at all: it can sit proud, load unevenly, or work loose. Getting that right once, then building it the same way every time, is the whole value.
Why we are showing it
Most of this site is large one-off equipment. This is the other half of what we do and the half we want more of: repeat production work, shipped on a regular schedule.
A part like this benefits from everything being in one company. Cutting, forming, welding and finishing happen here, so a reorder does not involve re-coordinating four suppliers and hoping the tenth batch matches the first.

Common questions
Crane Track Chocks: questions buyers ask
What does the chock actually do?
Shipyards use small tracked cranes for lifting at the dock. The chock slides between the tracks, the operator steps on it, and it spreads and locks in place so the machine cannot move while a lift is happening.
Is this a one-off or a production part?
Production. It ships on a regular basis and has done for years, which is exactly the kind of repeat work we are built for and want more of.
Could you build something similar for our equipment?
Probably, and the design would be specific to your machine: this one is engineered around one track geometry. Tell us the equipment and the problem and we will quote the design as part of the job.
Do you take repeat production runs generally?
Yes. Cutting, forming, welding, machining and finishing all happen in house, so a repeat part does not have to travel between four suppliers every time you reorder.
