HOIST TYPE:
STAHL’S Model SH Electric Wire Rope Hoist brings the new
generation of hoists to the market. It is designed to meet today's rigid space requirements and at
the same time maintains the quality and reputation developed by STAHL during the
last 100 plus years of experience. SH Hoists provide a sturdy product quality,

| HOIST MOTOR:
Siemens designed and manufactured, totally
enclosed squirrel-cage motors offer dependable performance
with a minimum of maintenance. Class F insulation and
embedded PTC thermal sensors for precise overheat-protection
enhance the modern design. |

Linings are asbestos free. The brake is
self-adjusting and should require minimum maintenance under normal hoist
operating conditions. |

HOIST GEARING:
Smooth running helical gears within a parallel shaft
gearbox. Gear wheels are honed after hardening to provide long life and low
noise levels. The gearbox is lifetime lubricated and maintenance free. |

ROPE DRUM:
Fine machining of the drum grooves reduces the rope wear
to a minimum. Drum grooves are machined to HMI recommended depth of 3/8ths of
the rope diameter. The drum is supported at each end by sealed bearings and is
driven directly from the helical gearbox.

WIRE ROPE: The wire rope is a
high-strength and flexible design for the SH hoist. The rated capacity load
divided by the number of parts of rope does not exceed 20% of the breaking
strength of the rope (rope safety factor is 5 or better). The rope is secured
to the drum with three (3) rope clamps. |

ROPE GUIDE:
Extremely wear resistant, made from cast steel alloy. No
temperature limitations. High resistance to side pull. It provides positive
winding of the rope on the drum and prevents rope overlapping. The wire rope
doesn’t ride on the “ridges” which prevents premature rope wear and damage. |

BOTTOM BLOCK: Sturdy, oversized
bottom block with low headroom. Steel sheaves rotate on double anti-friction
bearings. Forged alloy steel load hooks. Hook rotates full 360 degrees
supported on thrust bearing. Hook is equipped with a spring loaded safety
latch. |

LIMIT SWITCH:
Hoist is equipped with a geared upper and lower limit switch.
Located in the control panel for easy access. This switch is
easily adjusted to set the extreme upper and lower limits of
hook travel. The lower limit prevents “unwrapping” the rope
off the drum. |

Two wheels are driven, one on each side via. a splined cross
shaft. The "close headroom" trolley (shown) supports the hoist on one side of
the beam for better high-hook dimension. |

TROLLEY SUPPORTS:
Large round tubes support the trolley “halves”, allow for a wide range of flange
widths, make adjustment easy, and support the counterweight. |

Motors have Class F winding insulation and are totally
enclosed. Motors are protected from overheating by PTC sensors imbedded in the
windings. |

TROLLEY WHEELS: Trolley wheels are
cast steel alloy with self-lubricating properties. This gives low wear
characteristics and long life. They are single flanged to assure proper
alignment on the beam. |
