Adjustment of the trailer
As the brake shoe friction plates wear, the gap between the brake drum and the brake shoe friction plates will increase, and the stroke of the brake chamber push rod will also increase accordingly. If the stroke of the brake chamber push rod is more significant than 40mm, it indicates that the gap between the brake drum and the brake shoe friction plate is too large. At this point, it is necessary to adjust the wheel brakes. After adjustment, the stroke of the brake chamber push rod should be around 20mm. The stroke of the push rods in the two brake chambers of the rear wheel should be consistent to ensure that the left and right rear wheels brake simultaneously. The gap between the adjusted brake shoe friction plate and the inner surface of the brake hub should be measured at a distance of 20-30mm near the cam end, and the gap should be approximately 0.4mm; Measure at a distance of 20-30mm near the end of the pin shaft, and the hole should be 0.2-0.6mm. After releasing the brake, the brake drum should be able to rotate freely and not bite. After adjustment, a road test is required to check the braking performance and whether the brake drum is hot.
During locomotive transportation operations, the trailer braking should be 0.3 to 0.8 seconds earlier than the primary vehicle braking. When the brake pedal is pressed to 4/5 of the total travel, the trailer brakes and the primary vehicle brakes when further pressed. If the trailer brakes later than the main vehicle, it will cause the trailer to collide with the preceding vehicle, making it difficult for the driver to operate; If the trailer brakes too early, it may lead to traction, which can lead to issues such as frame stretching and brake cup damage.
What size trailer jack do you need for your ship
Know the weight of your ship
When determining the size of the trailer jack required for the vessel, the vessel should consider its "wet" weight, including the vessel itself, plus the weight of all loading equipment and fuel. It is essential to distinguish between wet weight and dry weight, as dry weight refers to the weight specified by the factory without any power or additional rigging. In other words, do not rely on your ship manual when choosing a ship trailer jack. The fuel on board weighs about 7 pounds per gallon, so depending on the size of the fuel tank on board, it may weigh 500 pounds or even more when fully loaded!
Generally speaking, a tongue jack should be able to lift at least 10% of the trailer weight, preferably 15%. This means that if your trailer has a total weight of 5000 pounds (which is common when adding bathroom/shower/sink water), the rated importance of your tongue jack should be at least 500 to 750 pounds.
Understand trailer frame dimensions.
Most people believe that the length exceeds 8 ½. Is the foot trailer 'too large' and subject to additional restrictions? Each state also specifies the maximum length of ship trailers and the maximum size of trailers and trailers (despite further changes). Jacking up longer ship trailers is more complex as they typically have a more uneven weight distribution and dual wheel design. More importantly, boatmen should pay attention to the width of the trailer frame when installing the bracket - most jack designs only apply to structures 3 inches high and 5 inches deep, and boatmen with trailer sizes exceeding these must ensure that the trailer jack can be adjusted to fit larger frames.
Understand the height of the hitch.
Most trailer hitch receivers are installed approximately 14 inches above the ground, although the spherical installation size may significantly change the height. To calculate the appropriate lifting height required, it is necessary to first measure the height of the tractor hitch and then increase it by 4-5 inches
