A portable, self-contained elevator climbing system removably attachable to an adjacent structure, said system comprising:
- a plurality of stationary, substantially linear roller chains having, individually addressable links, wherein at least one of said stationary, substantially linear roller chains is a drive chain, wherein at least one of said stationary, substantially linear roller chains is a stabilizer chain;
- a platform constructed to traverse said stationary, substantially linear roller chains, said platform further comprising:
- a motor having a primary axle;
- a closed loop hydraulic dampening assembly coupled to said primary axle;
- a braking assembly coupled to said primary axle, said braking assembly including at least one disc brake, said at least one disc brake having a caliper engagable with a rotor attached to said primary axle in response to a decrease in hydraulic pressure in said braking assembly;
- an adjustable diaphragm pressure switch in fluid communication with said braking assembly, wherein said pressure switch monitors said hydraulic pressure of said braking assembly, wherein said pressure switch causes said motor to start or stop at predetermined pressure points;
- a plurality of paired guide rollers, said guide rollers in each of said pairs being axially spaced and coaxially parallel;
- a plurality of sprockets having radially projecting teeth, each of said sprockets being offset substantially perpendicularly from said axis of said paired guide rollers, wherein said paired guide rollers cause said roller chain to firmly engage said sprocket respectively, wherein at least one of said sprockets is a drive sprocket attached to said primary axle, wherein at least two of said sprockets are stabilizer sprockets connected via a linkage to said drive sprocket, wherein said drive sprocket and said stabilizer sprockets are aligned in a substantially triangular orientation to stabilize said elevator climbing system;
- said linkage having a first linking sprocket attached to said primary axle, a second linking sprocket attached to a secondary axle having opposing ends and a linking chain forming a loop and engaged with said first and second linking sprockets, said stabilizer sprockets attached to each opposing end of said secondary axle such that said drive sprocket and said stabilizer sprockets are driven at substantially equivalent rates, wherein said primary axle and said secondary axle are substantially parallel;
- and
- a cantilevered bracket assembly removably securable to said adjacent structure, a end section of each of said stationary, substantially linear roller chains attached to said cantilevered bracket assembly, wherein said cantilevered bracket assembly provides proper alignment between said sprockets and said respective stationary, substantially linear roller chains;
- wherein said elevator climbing system is portable.
