Both people must agree on and understand the language they use to describe hoisting actions. If electronic voice communication is used, such telephone or radio, a dedicated channel must be used so that any commands from other personnel in the area will not confuse the operator. ANSI standard hand signals can be used for communication (see Annex – Ansi Standard Hand Signals). Other standards for hand signals exist. The operator must be trained in the use of appropriate hand signals. A copy of the hand signals should be displayed at the operator’s station and anywhere else where it could be useful. Special crane operations may require additional hand signals. Special signals must be agreed upon and understood before hoisting. It should not be possible to confuse special signs with the standard signs. The operator should only respond to hand signals from the person giving hoisting instructions, except to obey a stop signal, regardless of who gives it. The operator takes overall responsibility for crane movement and should only follow crane movement instructions when he or she judges it safe to do so. 21/79 R&M Materials Handling, Inc. reserves the right to alter or amend the above information without notice. R&M Materials Handling, Inc. 4501 Gateway Boulevard Springfield, Ohio 45502 P.: (937) 328-5100 FAX: (937) 325-5319 4 CONTROL DEVICES AND THEIR LOCATION 4.1 Main Isolation Switch The crane can only be driven when power is turned on. The owner must identify and document the location and function of the main isolation switch and must communicate this information to all operators of the crane. The main isolation switch must be situated close to the crane where it is easily accessible by the operator. The operator shall not operate the crane unless he or she knows the location of the main isolation switch. NOTICE Avoid turning off the main isolation switch during load movement. Sudden loss of power to the bridge may cause the load to swing and cause serious damage to the crane or load. When the main isolation switch is turned on after being placed in the off position, the set-up procedure must be followed before the crane can be used (see section Controller Set Up). 4.2 Controls for Crane Movements The speed of the trolley and hoist corresponds to the force applied to the direction control. These components move at their slowest speed when the pushbutton is partially pushed and at their maximum speed when the pushbutton is fully pushed. The selected component stops moving when the pushbutton is released. 1 When the pushbutton is released the hoist or trolley will stop moving. 2 When the pushbutton is partially pressed, the hoist or trolley will move at a slow speed. 22/79 R&M Materials Handling, Inc. reserves the right to alter or amend the above information without notice.

The plastic rings activate the upper and lower limit switches on the hoist. If a plastic ring is broken then it is a sign that a limit switch is not functioning correctly. Check for correct operation of the limit switches by raising and lowering the hook on low speed until the limit switches activate and prevent further upward or downward movement. 5 Safety latch Check to ensure that the hook safety latch is on the hook, is in good condition and closes automatically. WARNING 5.3 Never release the emergency stop button and drive the crane until you are sure that it is safe to do so. Crane Movements The crane moves in the following directions: Movements 1. Jib arm movements 2. Trolley movements 3. Hoist movements Description Jib arm slewing Horizontal movements of the trolley Vertical up and down movements of the lifting device Essential pre-requisites for this section 35/79 R&M Materials Handling, Inc. reserves the right to alter or amend the above information without notice. R&M Materials Handling, Inc. 4501 Gateway Boulevard Springfield, Ohio 45502 P.: (937) 328-5100 FAX: (937) 325-5319 NOTICE WARNING NOTICE Do not rely on the limit switches to stop the powered motions of the crane. Always stop the crane motion by using the control devices on the controller. When operating the crane, make sure there are no people situated underneath or nearby the load. Operating the crane when people are underneath or near the load could cause death or serious injury to those persons. If the crane malfunctions during use, push the emergency stop button and contact the supervisor. Note: Motors get hot when they are turning, even without a load on the hook. Operate the motors at the highest practical safe speed because low speeds generate more heat. Allow the motors to cool down frequently so that they do not overheat. Refer to the owner’s manual for the maximum permissible continuous operation times. If a motor gets too hot then the thermostat will prevent further operation. 5.3.1 Motor Control Methods The trolley and hoist are controlled by a variety of electrical circuits called “drive circuits”.

The following steps must be followed before lifting. WARNING Moving a load that is not properly attached to the lifting device could cause death or serious injury. Note: Do not attempt to lift a load which is fastened to the ground or to a base which will prevent it from being lifted. 5.4 Load Handling Correct load handling allows the operator to move loads quickly and safely. WARNING Handle the load safely at all times. During movements, ensure that the hook, the load, the crane and its moving parts will not collide with objects or people. Failure to do so could cause death or serious injury. Evaluating the load To prevent crane overloading, the operator shall determine the weight of the load before lifting. The operator shall only lift the load when he or she is sure that it weighs no more than the permitted load of the crane and accessories. The hoist overload device shall not be used to determine whether the load can be lifted. Never attempt to lift a load that weighs more than the maximum permitted load of the crane and accessories. NOTICE Attempting to lift a load that weighs more than the maximum permitted load of the crane and accessories could cause death or serious injury. Balancing the load The crane hook, slings and harnesses must be positioned so that the pulling force of the crane lies on the load’s centre of gravity so that the load is balanced. When the operator begins to hoist a load, he or she shall check that it is properly balanced before lifting it high off the ground. If the load is not balanced, he or she should lower it down and adjust the lifting point. 41/79 R&M Materials Handling, Inc. reserves the right to alter or amend the above information without notice. R&M Materials Handling, Inc. 4501 Gateway Boulevard Springfield, Ohio 45502 P.: (937) 328-5100 FAX: (937) 325-5319 1 Lifting centrally balanced loads The centre of gravity will usually be in line with the centre of the load. Provided that the contents of the container cannot move around, the balance of the load stays the same. 2 Lifting off-centre balanced loads The centre of gravity of an off-centre balanced load will usually be towards the heavier end of the load. Provided that the contents of the container cannot move around, the balance of the load stays the same. Shock loading The crane and accessories are designed to take up the weight of loads gradually and steadily. They are not designed to withstand sudden increases or decreases in the apparent weight of the load. Shock loading can occur in any situation where the load on the crane suddenly increases or decreases. Some examples of how shock loading can occur are shown below. 1 Change of load balance A change in load balance can suddenly pull on the hoisting rope or chain. 2 Unstable load If the load is unstable, it can exert sudden force on the hoisting rope or chain. The contents of packing cases should be securely fastened so that they cannot move around during lifting. 42/79 R&M Materials Handling, Inc. reserves the right to alter or amend the above information without notice. R&M Materials Handling, Inc. 4501 Gateway Boulevard Springfield, Ohio 45502 P.: (937) 328-5100 FAX: (937) 325-5319 3 Rapid load reduction A sudden loss of the load can cause the jib arm to spring back, causing damage to the jib arm and/or to its mounting points. In general, inching should be avoided because it can cause the jib arm to bounce. NOTICE Avoid shock loading the crane. Shock loading the crane could damage the crane or the load. Attaching the load The load is usually attached to the crane by means of some kind of under-the-hook lifting device. The most common under-the-hook lifting devices are chains, wire rope slings and lifting belts. The operator shall select a lifting device designed for the product being transported. Always follow instructions provided by the lifting device manufacturer when using under-the-hook lifting devices. Never use the crane’s ropes or chains a sling to attach to the load. Lockable hook If a lockable hook block is used, it is possible to lock the hook forging in steps of 90 degrees, to prevent load handling problems caused by rotating the load. 1 To avoid damaging the hook, lifting devices must only be positioned on the load bearing surface of the hook. That is, the lowest point of the hook. Forces on ramshorn hooks must be equal on both load bearing surfaces. 2 Ensure that the hook safety latches are closed. Check that the safety latch is not subjected to any force by the load. 43/79 R&M Materials Handling, Inc. reserves the right to alter or amend the above information without notice. R&M Materials Handling, Inc. 4501 Gateway Boulevard Springfield, Ohio 45502 P.: (937) 328-5100 FAX: (937) 325-5319 3 The weight of the load must be centered on the centre line of the hook forging so that the load does not bend the neck of the hook. Never try to lift anything with the tip of the hook! 4 Check that the load is balanced and safely fastened at the lifting points. The load must not be able to slide, slip or detach itself when suspended. 5 The hoist must be positioned directly above (perpendicular to) the load so that there are no side-pulling forces. The jib arm is liable to swing towards a load which is not situated directly under the hoist. 44/79 R&M Materials Handling, Inc. reserves the right to alter or amend the above information without notice.

CAUTION 7 The operator shall ensure that the crane or the load does not collide with anything or fall from the lifting device. NOTICE 45/79 Never drag loads along the ground or pull loads from the side. The jib arm is liable to swing towards a load which is not situated directly under the hoist. Observe the load at all times while it is in motion to ensure that it does not collide with anything or fall from the lifting device.

The crane will remain correctly aligned because alignment pins are used in the main girder and end carriage joints. Before moving the crane: y Verify that the new environment corresponds to the original environment which the crane was designed for. Using the crane in the wrong environment can shorten the lifetime of the crane. If you are uncertain, contact the crane manufacturer for advice. y Verify that the power supply at the new location is suitable. y Verify that the building structure and crane runway will support the nominal load of the crane. y Verify that the span between the runways exactly matches the crane. Modifications to the crane structure are not permitted without consulting the manufacturer. y Predict the future usage of the crane and calculate the remaining SWP time to decide whether it is worth moving the crane. While a crane near the end of SWP1 or SWP2 will need to have a General Overhaul very soon, a crane near the end of SWP3 is reaching the very end of its life. If you are uncertain about the usage, contact the crane manufacturer for advice. To assemble the crane, please consult Service personnel authorized by the product manufacturer.
