(d) Means shall be provided for fastening outrigger floats to outriggers when in use.
25-1.7.5 RaiL-Mounted Handlers
(a) Truck Wedges or lacks. Rail-mounted handlers shall be provided with removable wedges or jacks for transmitting loads from the base directly to the wheels without permitting the truck springs to function when handling loads. These wedges shall be removable, or the jacks releasable, in a manner positive for transit.
(b) Truck Center Pins. Each truck center pin shall be provided with a connecting means, such as a king bolt, to permit the truck weight to contribute to handler stability.
25-1.7.6 Welded Construction
All repair welding procedures shall be performed by qualified persons. Welding on load-sustaining members shall be performed in accordance with ANSL/AWS D14.3. Where special steels or other materials are used, the manufacturer shall provide welding procedures.
Repair welding on structural components shall not be done before obtaining the manufacturer’s or qualified person’s recommendations.
25-1.7.7 Guards for Moving Parts
(a) Exposed moving parts such as gears, set screws, projecting keys, chains, chain sprockets, and reciprocating or rotating parts that might constitute a hazard under normal operating conditions shall be guarded.
(b) Guards shall be fastened and shall be capable of supporting, without permanent distortion, the weight of a 200 lb (90 kg) person unless the guard is located where it is impossible for a person to step on it.
25-1.7.8 Hydraulic and Pneumatic Line Protection
Exposed lines subject to damage should be protected.
25-1.7.9 LubricatIng Points
Lubricating points should be accessible without the necessity of removing guards or other parts.
25-1.7.10 Handler Modifications
Structural modifications or additions and/or hydraulic modifications that affect the capacity or safe operation of the handler shall not be made without the written approval of the manufacturer, assembler/modifier, or a qualified person. Modifications to the handler affecting lifting capacity require a revised lift capacity chart.
(a) The fuel tank filler pipe shall be located or protected so as not to allow spill or overflow to run onto the engine, exhaust, or electrical equipment of the handler being fueled.
(1) The toolbox, if provided, shall be nonflammable and secured to the handler.
(c) A horn shall be provided that can be operated while allowing the operator to maintain control of the primary function.
(d) A flashing light should be installed on equipment where the operator does not have a 360 deg unobstructed view. A single light may be mounted so that it has 360 deg visibility, or three lights may be used; one on each rear corner and one on the front corner opposite the operator. The light(s) shall activate whenever the swing and/or travel function is engaged.
(e) Means shall be provided for checking the manufacturer’s specified pressure settings.
(I) A warning sign shall be installed, visible from the operator’s station, warning that electrocution or serious bodily injury may occur unless a minimum clearance of 10 ft (3 m) is maintained between the handler or load for energized power lines up to 50 kV, and that greater clearances are required for higher voltages (refer to para.
(g) Means shall be provided for the removal of air in each hydraulic circuit.
SECTiON 25-1.8: ELECTRICAL EQUIPMENT
(a) Magnet or electric motor power wiring and equipment shall comply with ANSI/NFPA 70.
(b) All handlers shall be equipped with a main power disconnect switch of the enclosed type and that is lockable in the open (off) position.
25-1.8.1 Lifting Magnets
(a) A handler used with a lifting magnet shall comply with ASME B30.20, Chapter 20-4, Group IV (Remotely Operated lifting Magnets). Persons shall not be in close proximity to an energized remotely operated lifting magnet, except for electrical testing. If a lifting magnet is used in close proximity to people, it shall comply with ASME 830.20, Chapter 20-3, Group III (Close Proximity Operated Lifting Magnets).
(b) A handler used with a lifting magnet that is powered by an on-board DC generator shall be equipped with a separate circuit switch that disconnects the power to the magnet, or disconnects excitation power to the DC generator and removes all power to the magnet. The switch shall be of the enclosed type with provisions for locking, flagging, or tagging in the open (off) position. Means for discharging the inductive energy of the magnet shall be provided.
(c) Indicator or signal lights shall be provided to indicate whether the power to a lifting magnet is on or off. This light shall be visible to the operator.
