Fixed Type Hoist (Without Trolley) : HB Series

Product Features

* HOSTING MOTOR
It is 3phase squirrel cage induction motor designed under the performance standard of KSC-9621(equivalent to ISO4301)to endure the high operation cycle with continuous rating time(30min) and 125% rated load.
There are two kinds of motors what we apply, one is T.E.N.V(Totally Enclosed Non-Ventilated Type below 17kw motor capacity and T.E.F.C (Totally Enclosed Fan Cooled)type over 17kw motor capacity.

* HOSTING BRAKE
It is composed of electric magnetic disc brake with good reaction released with spring by power. The brake still holded in power failure and slip ratio less than 1% per min of hoisting speed under the 100% load weight.
The brake torque suspend over 150% under the rated load weight.

* UPPER LIMIT SWITCH
It is designed two step stopping system with LEVER CAM. First stop on the limited highest cut off control power circuit and if the control power do not off, main power circuit off secondly the lever cam on the maximum highest limit.

* TROLLEY
In case of mono rail hoist, the flange width available to adjust I beam(H-beam)size on the brochure with the spacer and in case of double rail hoist the trolley span adjustable to non standard size. All the wheel adopt grease enclosed ball bearing standing hoist lood condition, easy exchange for maintenance. Wheel taper approx. 8 degree angle for I-beam and available to adopt H-beam as plain wheel without taper.

* CONTROL PANEL
It is composed of E.O.C.R to protect the motor and N.F.B to protect Hoist demage and two step lever cam to control highest limit.
The operation of electromagnetic contactor interlock the each motion with safety for any shock. Panel box adopt rubber pad sealing in order to protect vibration and waterproof.

* PUSH BUTTON SWITCH
Adopted mechanical interlock system guide safety operation, the case raw material used polycarbonate is strong against impact.
Ingress Protection group is 65 and the switch model has toggle switch for multi-operation of two hoists on the same girder, one step push button for single speed, two step push button for dual speed operation. The button points has basically emergency for all motions with the preferable motion numbers.

* WIRE ROPE
It is designed safety factor 5 times or more under considering sheave efficiency.
Rope diameter of all models use more than 8mm with 6 core construction X19(37) filaments swirl Z twisted A or B type

* REDUCTION GEAR
Considering enough hardening strength, gear raw materials adopt alloyed steel(S.C.M or S45C) and gear tooth treated induction hardening reduce noise with smooth during operation in particular, enhancing the endurance of wear-out & abrasion resistance structurized hard surface layer, elastic inner layer.
Lubrication way apply oil batch type.

* PUSH BUTTON CABLE SHOCK ABSORBER
To protect the disconnection of push button cable to hoist panel, attached cable shock absorber into the hoist frame with harness & spring.(Independent push button system excluded this system)

* LOAD BLOCK AND SAFETY HOOK
Composed of hook, hook beam, sheave and sheave shaft and the hook available to circulate 360 degree by hand under the rated load and attached the safety latch to open inside direction not to release the sling rope.

* GEARED MOTOR
Brake power incorported with D.C magnetic friction disk keep over 100% in the rated motor circulation power and It is available to adjust brake power.
The motor geared with reducer designed by the optimum reduction ration with motor capacity induce smooth operation in inching, start and stop.

* OPTIONAL DEVICE
Load limiter
When the loaded weight over rated load, the limiter sound buzzer consistently turn on the red lamp.
There are two kinds of types. one is analogue and another is digital and both available to adjust the desirable load weight.

Trolley limit switch
When the hoist travel to the cross direction, the limit switch turn off the electricity of trolley motor before the trolley stop into the stopper device attached the girder.

Lower Limit Switch
It is designed with electro mechanical stop system by limit switch to protect the reversing rope. It is indispensible to apply model of high lift height hoist.

Double I-beam Trolley
the super lift height of mono rail hoist apply double I-beam type double trolley to reduce maximum the swing of loaded cargo with rope.

Radio controller
If the operation site is dangerous of difficult approach position, or requring high effciency productivity, the radio remote controller can be used and one controller can be used for several cranes. Several radio controller using in one site do not entangled with other radio controller protecting mis-operation each other.
