A 4-T crane is used to lift a 3m x 1.2m x 200mm pre-cast panel. A preader beam is needed to ensure the proper distribution of load in the lifting chains.

A crane is used to lift 10000 kg of coal from a mine 100 m deep. If the time taken by the crane is 1 hr, then find the power of the crane, assuming the
(c) The Drop Zone(s) and Load Crush Zone(s), and the criteria for when (if at all) Lift. Crew members may enter them. Page 5. ExxonMobil Use Only. Crane and
50 N × 1500 m = 75000 J (since 1 J = 1 Nm). i.e. work done = 75 kJ. 2. Calculate the work done when a mass of weight 200 N is lifted vertically by a crane
Therefore use a sling with a lifting capacity greater than 4.62 tonnes. 4. To calculate the SWL of the sling needed to lift this load, divide the load by the
