More Description for Rite-Hite 503
A dock leveler hold-down can be mechanical, hydraulic, or electrical. The purpose of a hold-down is to maintain the dock leveler at a set height below, at, or above the loading dock when it is not being used. If ramp control teeth are damaged, or brake systems are worn on a load dock leveler, the dock leveler can pop up, which creates an unsafe condition.
This part is for Rite-Hite mechanical dock levelers. It is a hold-down ramp control replacement part that stabilizes the dock leveler and minimizes the possibility of dock leveler pop-ups.
Questions & Answers
Ask a Question-
What is the difference between the 503 and 503AR?
The AR in the 503AR stands for Auto-Release. This feature automatically recycles the holdown during use, which in-turn relieves the excessive stress put on the dock leveler caused by air-ride trailers.We recommend anyone looking at the 503 should consider upgrading to the 503AR.
