Support assembly for a building material

A lift assembly for supporting and raising a building material, the lift assembly comprising:

• a support body;
• a support platform movably coupled to the support body and having a support surface and a sidewall extending from the support surface, wherein:
• the support surface is configured to support the building material, and
• the sidewall is configured to at least partially surround an upper portion of the support body;
• and
• a lift mechanism operably coupled to the support platform and configured to selectively raise and lower the support platform relative to the support body, the lift mechanism including:
• a rotatable actuator coupled to the support body,
• a worm gear operably coupled to the rotatable actuator, and
• a rack and pinion assembly operably coupled to the worm gear and to the support platform, the rack and pinion assembly configured to selectively raise and lower the support platform relative to the support body upon rotation of the rotatable actuator and the worm gear.

A support assembly for a building material, the support assembly comprising:

• a mounting portion configured to selectively mount the support assembly to a wall frame, the mounting portion including a first mounting arm and a second mounting arm, wherein:
• the first mounting arm and the second mounting arm collectively form a clamping mechanism,
• one of the first mounting arm and the second mounting arm includes a pin configured to grip into a first side of the wall frame, and
• the other of the first mounting arm and the second mounting arm includes a tightenable fastener configured to tighten against a second side, opposite the first side, of the wall frame;
• a support platform coupled to the mounting portion and having a support surface configured to support the building material;
• and
• a lift mechanism including a rack coupled to the support platform, and a worm gear operably coupled to the rack and rotatably coupled to the mounting portion, the lift mechanism configured to selectively raise and lower the support platform relative to the mounting portion upon rotation of the worm gear.
