![]() ![]() (ii) When the wind reaches the crane's shutdown speed: (B) The crane shall be readied for shutdown. (i) When the wind reaches the crane's warning speed: The instructions shall include procedures for responding to high wind alerts and for any coordination necessary with other cranes. Operators shall be directed to comply with these instructions. The employer shall post operating instructions for high wind conditions in the operator's cab of each crane. (A) When wind velocity reaches the warning speed, not exceeding the crane manufacturer's recommendations and (B) When wind velocity reaches the shutdown speed, not exceeding the crane manufacturer's recommendations, at which work is to be stopped and the crane secured. That warning shall be transmitted whenever the following circumstances are present: (ii) The wind indicating device shall provide a visible or audible warning to alert the operator of high wind conditions. (i) After October 3, 1983, each rail-mounted bridge and portal crane located outside of an enclosed structure shall be fitted with an operable wind-indicating device. Marking shall be legible from the ground level. If there is more than one hoisting unit, each hoist shall have its rated load marked on it or on its load block. The rated loads of bridge cranes shall be plainly marked on each side of the crane and in the cab. (1) For the purpose of this section, rail-mounted cranes include bridge cranes and portal cranes. (g) Rail-mounted cranes (excluding locomotive types). If the inspector can immediately find the exit, no exit sign would be required. If the inspector gets "lost" you need exit signs. The important words are immediately visible. ![]() The same floor space, made up of individually separate rooms, in a maze configuration, with no windows, illuminated exit signs may be required to allow employees a safe. The interpretation of is vital If you have a square room with windows and no partitions, an exit sign would not be needed. ![]() The requirement for exit signs is not the number of employees in an establishment, but the physical layout of the building. This is also what is used for scaffold requirements as incorporated into the construction standards, 1910.28(a)(18). The two documents could be used as guidelines for construction cranes. The dock workers start getting concerned at 20-25 mph because in the Bay Area there are a lot of gusts, it is not steady winds. In our discussions during Cal/OSHA advisory meetings, the cranes on the docks usually follow the procedure set in the table 2-A ( Attachment 2 ). Note this standard is for rail mounted cranes. There is a standard in the new "Marine Terminal" standard paragraph 1917.45(g)(3) - ( Attachment 1 ). Send Skyview your requirements and we can add to this custom kit with upgrades such as a wind direction sensor, a secondary display or Yagi antenna for extending the range of your equipment.There is not a construction standard for the use of cranes during high wind conditions. The Wi-fi capable display means users can enable remote monitoring via a phone or computer.Įach basic kit includes a simple “self-levelling” anemometer, with magnetic mounting bracket and safety cable, an LCD display, fully adjustable display mounting bracket, operating manual and calibration certificate. Offering customers a choice of power supplies, the hard wired 12v-24v DC or a "C" type battery powered display provides users with current wind speed, programmable alarms and bar graph features. Suited to all industrial environments the W410XB is most commonly used on construction sites and mobile cranes for instant wind speed and direction data. The one-stop option requires no calibration or adjustments, just remove from the box, install and go to work. Each Wireless Anemometer and Display kit provides customers with a cost effective solution for wind speed and direction monitoring.
