Standard Hoist Features
Traction Hoists
Spider traction hoists are load sensitive—traction automatically
adjusts to match the applied load. The units are lightweight and modular.
Each model has a built-in overspeed brake which is automatic when needed
and can also be manually activated.
A second wire rope brake is standard. The hoists travel at a maximum
allowable travel speed of 35 FPM. One lever release allows the controlled
descent feature to gently lower the system without power. All Spider
traction hoists are self-reeving. An indicator light confirms power
to the hoist. Operator
has
control of a full power cut-off switch in case of emergency.
Drum Hoists
Spider drum hoists are work cages with built-in hoisting capabilities.
The wire rope is secured by a swaged cable drum hook. Spider’s
unique level wind system automatically collects the wire rope neatly
on the drum. There are no dangling ropes under the work cage. Each
unit has a built in overload device and secondary overspeed brakes.
Spider drum hoist work cages provide a very stable work platform with
a low center of gravity. 500’ and 1000’ wire rope drum
capacities available on most models. Fly decks can be added to all
full size Spiders,
increasing the working swath by up to 6 feet.
