A material handling lift comprising:
- a mast;
- a platform coupled to the mast;
- a power unit configured to drive the platform along the mast to a raised position and lower the platform to a lowered position;
- and
- a roller shade having a first end coupled to a top of the mast and a second end coupled to the platform, the roller shade being configured to extend along a length of the mast when the platform is lowered to the lowered position and to retract toward the top of the mast when the platform is raised to the raised position.
A material handling lift comprising:
- a power unit configured to drive a component of the material handling lift for moving an object;
- and
- a scanner positioned to scan a protected area adjacent the material handling lift for presence of a person and provide a scanner output if the person is detected in the protected area, the power unit being responsive to disable drive of the component in response to the scanner output.
A material handling lift comprising:
- a mast;
- a platform coupled to the mast;
- a power unit configured to drive the platform along the mast to a raised position and lower the platform to a lowered position;
- at least one guard panel positioned adjacent a side of the platform;
