Double Beam Girder Wire Rope Electric Hoist used for factory warehouse
DTEH wire rope electric hoist create the greatest value for the customers with the excellent durability, high quality and
cost-effective. DTEH-02 is for double girder overhead travelling and gantry cranes.
DTEH wire rope hoist is designed and manufactured according to FEM European standard and DIN German standard, which
is a new and environment friendly product. The hoist adopts modular C-design. The product provide compact structure,
low headroom, stable lifting operation, accurate positioning. The maximum hoisting load is 20 tons.
Brief Intriduction
DONGTAI DT hoist benefits at a glance.
Modular C-design is optimised for crane applications with compact overall dimensions and reduced approach dimensions,
which brings optimal use of space and reduce plant construction cost.
High operating safety and reliability by smart control system with Inverter The inverter makes the lifting and travelling speed
faster and more accurate under high load conditions, which greatly improves the working efficiency. The mechanical load is associated with many components, making start and stop smoother and completely immune to overload. In addition, energy consumption is lower due to optimal power.
Super quality three in one gearmotors, high strength steel wire ropes, Welding reel drums, inverters and durable electrical
and mechanical components ensuring the long life cycle of the hoist and reduce the maintenance cost.
Hoist Components
Hoisting Motor
1. 3 in 1 double-winding squirrel-cage pole-changing dual speed hoisting motor with stable and reliable operation, and
free of maintenance.
2. 60% ED power continuity.
3. Motor IP55 protection class and F insulation class.
4. Thermal resistor or thermal switch is embedded to prevent motor overheating.
Trolley Motor
1. 3 in 1 variable speed inverter controlled motor with stable and reliable operation and low noise.
2. 40% ED power continuity.
3. Aluminum alloy shell with light weight and easy to dissipate.
4. Compact brake, self lubrication, free of maintenance.
Brake
The hoisting motor equips double-disc electromagnetic brake. Brake integration locates at the end of motor. The brake
will automatically close if the motor powers off in order to avoid load slipping off. The brake clearance does not need to
be manually regulated (which can be regulated automatically by brake spring) after being initially set, if the thickness of
brake pad is lower than the setting, it will automatic alarm through additional monitor switch in order to remind user to
replace. Double-disc electromagnetic brake is safe and reliable, the brake torque is higher than 1.8 times of rated torque,
the number of braking gets to 1,000,000 times and it does not need maintenance in the safety service life cycle.
In conclusion, the brake is with technical features and benefits of fast movement and high reliability, maintenance free and
self-regulated, dustproof and long service cycle.
Reel
The reel is made of high-quality seamless pipes and processed by numeral control machines, after the special finishing,
the rope groove on reel works coordinately with rope guide to efficiently prevent rope loose and tangling.
Steel Rope
Imported high strength steel wire rope with tensile strength of 2160kN/mm², steel wire surface galvanized to prevents rust.
So we can ensure the wire rope with good safety performance and long service life.
Rope Guide
Standard rope guide is made and processed by engineering plastics with strong abrasion resistance and good
self-lubricating performance, which greatly reduces the wear of steel ropes as main force safety components and then
enhances safety of hoisting mechanism. Meanwhile, based on specific working condition, the heavy grade rope guide
made of ductile iron is also available.
Electric Control Cabinet and Electric Protection
Electric Control Cabinet surface is dealt with through antisepsis plastic spraying, reasonable layout and easy maintenance,
with IP55 protection class. Working environment temperature shall be lower than 45℃ and the humidity shall be less than 90%.
