DESCRIPTION OF PRODUCTS

Combining chain block and a manual trolley, both traveling and lifting are made possible with minimal distance from beam to lifting hook (”H” value). Therefore, Low Headroom Hoist is the perfect choice when working under low to very low ceiling height (mines, ships …). Moreover, Low Headroom Hoists come in various versions, DLHP model is our basic version, DLHG on the other hand includes hand chain for traveling and DLCG is designed to fit a curved beam track with a minimum radius curve as low as 1000 mm. Most models are available in Explosion proof version

HOW TO OPERATE

DLHP models are operated just like any Chain Block from Black Bear, pulling one of the two hand chain will either lift or lower the laod. DLHG models has two set of hand chain, one for lifting and lowering the load, the other set to travel the hoist and its load along the beam track. DLCG models are operated like DLHG models.

CAUTIONS AT USE

Low Headroom Hoist is designed to bear vertical loads only. When lifting a load, upper hook, bottom hook and load chain should be aligned in vertical position in order to bear the safety load. According to Occupation Safety and Health Acts, hook and load chain of Low Headroom Hoist should be replaced if the entrance of hook is stretched by more than 10% or if load chain is stretched by more than 5%. Load chain, hook and chain pin which are directly bearing the load should be checked regularly since stretched length is difficult to measure through visual inspection. Hoists are devices that are easily exposed to risk of overload, be careful when using such devices.

CAUTIONS AT PRODUCT SELECTION

Low Headroom Hoist cannot lift loads above the minimum distance (”H” value). Compatibility between hook and lifting component (lifting eyes, slings, etc.) should be checked prior to handling any lift. Low Headroom Hoists Plain and Geared type has a minimal value for ”H1”, but for a same load capacity Low Headroom Hoists Curved Beam Type has a greater ”H1” value; do take those parameters in account when choosing your product. Do not hesitate to contact us for further information concerning Low Headroom Hoists.

STRUCTURE

ultra_low_headroom_hoist_structure

Hand chain can be and should be adjusted according to operator height. We recommend keeping a 500 mm distance between the bottom of the hand chain and the floor to prevent dragging the hand chain on the ground.

  • LOAD CHAIN LENGTH=H+L
  • LOAD CHAIN LENGTH(C/B)=LOAD CHAIN LENGTH-500
  • LOAD CHAIN LENGTH(T/R)=LOAD CHAIN LENGTH-500
  • Loads cannot be lifted above “H” value.

Plain Type

FEATURES

DLHP model does not include a separated traveling device; therefore, traveling is obtained by pushing the load or the bottom hook.

FEATURES

DLHG model includes a hand chain to operate the traveling device. Depending on which fall of the hand chain is pulled, the hoist will move forward or backward along the beam track.
