  1. The information in this show is for the following crane classes: Tower Cranes Vehicle Loading Cranes Bridge and Gantry Cranes Derrick Cranes Portal Boom Cranes Non-Slewing Mobile Cranes Slewing Mobile Cranes

  2. Question 2. Calculate the Working Load Limit (WLL) of one of the following: 2 2 2 Formula: D =WLL (kgs) Formula: D =WLL (kgs) Formula: D =WLL (kgs) (3) 20mm diameter unidentified synthetic rope. (1) 12mm diameter unidentified synthetic rope. (2) 15mm diameter unidentified synthetic rope. Answer: 20mm = 20 x 20 = 400 kg WLL. Answer: 12mm = 12 x 12 = 144 kg WLL. Answer: 15mm = 15 x 15 = 225 kg WLL. Note: Where a manufacturers tag or specification is not supplied for a synthetic rope the formula for fibre rope should apply or be accepted.

  3. Question 30. List two effects “double blocking” can have on the crane and equipment. Answer: Can damage sheave Can cause the FSWR to break Can cause structural damage to the crane Can cause the load to drop

  4. Question 72. What details are displayed on a spreader / lifting beam? (List at least three). Answer: Tare weight of the beam. Registration number. Approval plate. SWL / WLL. SWL 25t TARE – 250kg EGA-2005

  5. Question 102. Find the total weight of a load made up of the following: 4 universal beams each 8 metre long; 15 scaffold planks each 4.4 metres long; 2 mild steel plates 4 metres long and 0.5 metres wide. Answer: 5,086 kg. One metre of universal beam weighs 125 kg One metre of scaffold plank weighs 7 kg One square metre of mild steel plate weighs 156 kg Workings: (4 x 8 x 125) + (15 x 4.4 x 7) + (2 x 4 x 0.5 x 156) = 5086kg
