Cages are mandated to begin between 7' and 8'(2250 mm) from the ground and extend the entire length of the ladder. Cages can have left hand exits (opening in the LH side of cage), right hand exits (opening in RH side of cage), top exits (for exit through a hatch or floor door), and walk through exits (for exit through back side of fixed ladder).
Caged IBCs are often 1,200 x 1,000 x 1,150 (45" x 40" x 46") for 1,000 L and 1,200 x 1,000 x 1,350 mm (48" x 40" x 53") for 1,250 L, where both volume types are available in either new, rebottled, or reconditioned model types, where: rebottled means a brand new HDPE liner in a previously-used but certified steel cage, and; reconditioned means a ...
The standard rail weight for British railways is now 113 lb/yd (56.1 kg/m). Before the 1990s, most diesel locomotives were built to a maximum axle load of 19 long tons (19.3 tonnes; 21.3 short tons) so the maximum locomotive weight was 76 long tons (77.2 tonnes; 85.1 short tons) for a four-axle locomotive and 114 long tons (115.8 tonnes; 127.7 short tons) for a six-axle one.

There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such as those made of rope or aluminium, that may be hung from the top.
In the 1920s, the novelist and engineer Nevil Shute Norway (he called his autobiography Slide Rule) was Chief Calculator on the design of the British R100 airship for Vickers Ltd. from 1924. The stress calculations for each transverse frame required computations by a pair of calculators (people) using Fuller's cylindrical slide rules for two or ...
The ladders are made by threading and fixing a series of hardwood, machined steps, each not more than 400 mm × 115 mm × 25 mm (15.75 in × 4.53 in × 0.98 in), onto two pairs of minimum 18 mm (0.71 in) diameter manila ropes, and binding each step to the ropes at 310 mm (12 in) (+- 5 mm, 0.20 in) intervals.
