A system will be set up that prevents all access that may endanger people or the crane
Any moving part, which may pose a danger to people, must be effectively protected and indicated
Provision for safe access of personnel to and around equipment for functions
All stairways giving access to the bridge, diver’s cabin, etc. shall have tread and a ratio or rise not exceeding 450 and width of at least 600 mm
Back protection shall consists of three vertical stringers interconnected by rings spaced at 600 mm interval. The wall of the ladder well opposite to the ring plane shall be located at a distance not exceeding 600 mm from these rungs
Deck shall be built, according to rules, at the heads of the bridge to facilitate maintenance of the collector shoes of the bridge and of the wheel assemblies, whenever the crane structure does not permit such maintenance from inside the crane. Access shall be ensured by means of a stair and irremovable hinged trapdoor. Opening of this trapdoor shall be such as to prevent any contact with moving parts and the personnel shall not be exposed to the hazard of empty space
All rotating members (couplings pulleys, gear, etc.) shall be protected by sturdy carters in plate. All heavy covers shall be provided with inspection windows. The carters of the driving and idle wheels of bridge and trolley shall be fitted with irremovable hinges. Large-sized protections and guards shall open horizontally to permit removal of the upper part during inspection without need to remove the lower part.

The walkways shall be provided with handrails and toe board in compliance with safety regulation on the outer side of the crane. Handrails with toe board shall be installed on the trolley sides. The distance between these handrails and the trolley gears shall be such as to provide easy access for maintenance purposes
These limit switch shall be mounted without varying the free space on the bridge and trolley and shall always leave a clearance of at least 600 mm along the runway. The mechanical components of power limit switches shall be suitably anchored so as to prevent their falling down in case of failure
All working parts and lubrication points in so far as possible are to be arranged for easy accessibility, convenience of operation, inspection, lubrication and ease of replacement with minimum downtime. Provision for access ladders/staircases will be made at the following location and wherever else found necessary: - Crane railway to crane walkway - Crane walkway to operator’s cabin - Crane walkway to power collector inspection platform where provided. - Crane walkway to wheel inspection platform where provided - Trolley floor to crane walkway
The crane will be designed in order to minimize maintenance and make unavoidable maintenance safe, quick and easy. In order to minimize the frequency of maintenance, the temporary table of inspection and maintenance of crane components, contained in the offer documentation, must be drawn up in terms of previous engineering experience and subsequent improvements. The final table, which will be coherent with the temporary one, will be included in the instruction and maintenance manual and will be contractually binding. Each crane component must be configured according to the following maintenance requirements: The components to be maintained and/or inspected must be easily accessible with minimum disassembly; all guards covering components must be hinged and have quick locking systems and stays for their open positions. Every component must be easy to handle and equipped with hooks to allow them to be properly balanced when lifted.
