A ladder support apparatus, the apparatus including a support body, one or more clamp mechanisms operatively mountable to the support body, for mounting the support body to a structure and a retention assembly operatively connected to the support body and, in use, being adapted to limit relative movement between the ladder and ladder support, the or each clamping mechanism including a clamp aπn mounted for movement relative to the support body in a clamping direction and a release direction, an actuator operable to control the operation of the clamp arm, the clamp mechanism being arranged so as to be able to adopt a preset mode in which the clamp arm is substantially freely moveable in both the clamping direction and the release direction, a set mode in which the clamp arm is inhibited from movement in either direction but can be moved incrementally by operation of the actuator and a pre-release mode in which the clamp arm is inhibited from movement in either direction but upon operation of the actuator when in the pre-release mode the clamp arm can return to its preset mode.

1. A ladder support apparatus, the apparatus including a support body, one or more clamping mechanisms, operatively mountable to the support body, for mounting the support body to a structure and a retention assembly operatively connected to the support body and, in use, being adapted to limit relative movement between a ladder and the support body, the or each clamping mechanism including a clamp arm mounted for movement relative to the support body in a clamping direction and a release direction, an actuating lever operable to control the operation of the clamp arm, the clamping mechanism being arranged so as to be able to adopt a preset mode in which the clamp arm is substantially freely moveable in both the clamping direction and the release direction, a set mode in which the clamp arm is resisted in either direction but can be moved incrementally in the clamping direction by operation of the actuating lever and a pre-release mode in which the clamp arm is inhibited from movement in either direction, but upon operation of the actuating lever when in the pre-release mode the clamp arm can return to the preset mode, said clamping mechanism including a brake device which in a braking position, when the mechanism is in the set mode, provides resistance to movement of the clamp arm, a control arm pivotally movable so that when the clamping mechanism is in the preset mode, the brake device is caused to adopt a non-braking position, a catch element operable to engage the control arm when in the set mode so as to hold it in the set mode, a drive link operatively associated with the control arm, and said actuating lever and said drive link operable to cause said incremental movement of said clamp arm when in the set mode. 2. A ladder support apparatus according to claim 1 wherein said retention assembly includes two ladder retention devices each adapted for association with a respective ladder stile the device including a bracket which is operatively connected to the support body and includes a plurality of guides arranged in spaced apart relation for receiving the ladder stile with which it is associated therebetween, the guides being arranged to enable relative movement between the ladder and the retention devices in the direction of the stiles, but inhibiting relative lateral movement. 3. A ladder support apparatus according to claim 2 wherein the position of the guides are adjustable relative to one another. 4. A ladder support apparatus according to claim 1 wherein each clamp arm is mounted for relative linear movement with respect to the support body, towards the support body in the clamping direction and away from the support body in the release position. 5. A ladder support apparatus according to claim 1 wherein each clamp arm can be removed and replaced with clamp arms having different clamping arrangements when the clamping mechanism is in the preset mode. 6. A ladder support apparatus according to claim 1 wherein the apparatus includes an activating element which enables the actuating lever to be activated from a base portion of a ladder with the apparatus being disposed in spaced relation from the base portion. 7. A ladder support apparatus according to claim 1 wherein said support body is an elongated member comprising a plurality of components which are arranged so that the length of the elongated member can be adjusted. 8. A ladder support apparatus according to claim 1 further including a lift mechanism operable so as to enable the apparatus to be moved along the ladder between one end region, being the base of the ladder, and the other end region of the ladder that is spaced away from the base of the ladder, the lift mechanism being operable from the base of the ladder. 9. A ladder support apparatus according to claim 8 wherein the lift mechanism includes a flexible line operatively connected to the support body and arranged to pass over a ladder rung at the other end region so that the line, when pulled, will move the apparatus along the ladder. 10. A ladder support apparatus, comprising: a support body;one or more clamping mechanisms, operatively mountable to the support body, for mounting the support body to a structure, each clamping mechanism having a housing;a retention assembly operatively connected to the support body and structured such that, in use, the retention assembly is adapted to limit relative movement between a ladder and the support body;a clamp arm connected to each clamping mechanism and mounted for movement relative to the support body between a clamping direction and a release direction;an actuating lever operable to control the operation of the clamp arm;a brake device structured to provide resistance to movement of the clamp arm when the brake device is engaged in a braking position when the clamping mechanism is in the set mode;a control arm pivotally attached to the housing of the clamping mechanism and being movable so that when the clamping mechanism is in the pre-set mode, the brake device is caused to adopt a non-braking position;a catch element positioned and operable to engage the control arm when the clamping mechanism is in the set mode so as to hold the control arm in the set mode; anda drive link connected to the housing and operatively associated with the control arm, said drive link and said actuating lever being operable to cause incremental movement of said clamp arm when in the set mode, wherein the clamping mechanism is arranged so as to be able to adopt a preset mode in which the clamp arm is substantially freely moveable in both the clamping direction and the release direction, a set mode in which movement of the clamp arm is resisted in the clamping direction and the release direction but can be moved incrementally in the clamping direction by operation of the actuating lever, and a pre-release mode in which the clamp arm is inhibited from movement in either the clamping direction or the release direction, but upon operation of the actuating lever when in the pre-release mode, the clamp arm can return to the preset mode.
