Altam ramps are fabricated to ensure safety and performance. “x3 of your heaviest forklift capacity that you will be using”.
In Example if your forklift capacity is 6000lbs you would x (multiply by) 3 = 18,000lbs Capaity ramp would be required which we fabricate to a min of 20,000lbs.
By using this formula we can detemrine the thickness of material used in our cross members, along with adding any reinfocements necessary to based of a 2:1 safety factor. Altam fabricates custom capacities upon request.
|Standard Ramp Capacity|| Max Forklift Weight |
| 20,000lbs|| 6,500lbs|
| 25,000lbs|| 8,000lbs|
| 30,000lbs|| 10,000lbs|
| 35,000lbs|| 11,500lbs|
| 40,000lbs|| 13,000lbs|
Please add 5,000lbs to the board capacity when using a 3-wheel forklift or trucks using a paper roll clamp.

Dockboards are capable of supporting the maximum intended load in accordance with § 1910.22(b);
Dockboards put into initial service on or after January 17, 2017 are designed, constructed, and maintained to prevent transfer vehicles from running off the dockboard edge;
Exception to paragraph (b)(1) of this section. When the employer demonstrates there is no hazard of transfer vehicles running off the dockboard edge, the employer may use dockboards that do not have run-off protection.
Portable dockboards are secured by anchoring them in place or using equipment or devices that prevent the dockboard from moving out of a safe position. When the employer demonstrates that securing the dockboard is not feasible, the employer must ensure there is sufficient contact between the dockboard and the surface to prevent the dockboard from moving out of a safe position;
Measures, such as wheel chocks or sand shoes, are used to prevent the transport vehicle (e.g. a truck, semitrailer, trailer, or rail car) on which a dockboard is placed, from moving while employees are on the dockboard; and
Portable dockboards are equipped with handholds or other means to permit safe handling of dockboards.
