About ALLMAN
Nantong Allman Industry Co., Ltd. specializes in hoisting and lifting equipment, offering electric winches, cranes, and hoists for industries like construction, mining, and offshore. With 20+ years of experience, we ensure quality and safety through compliance with European standards.
Located in Wellman Machinery, No.186, Tiantong Road, Nantong city, Jiangsu Province, China, Allman factory takes a cover of 6600 square meters. For electric chain hoist, we have the biggest factory, can output over 5000 units electric chain hoist per month. As for the electric winch, we are one of the only two manufacturers of heavy duty electric winch, quality is the No.1 in China. Our engineers are still keeping developing more electric lifting winches like multipurpose electric winch, small electric winch to fit for different use situation.
Moreover, ALLMAN is also a trustworthy supplier of other hand operated lifting tools like chain block, lever hoist, magnetic lifter, lifting clamps, girder trolley, hand pallet truck, steel wire ropes, aluminum and fiber-glass ladders and so on.


Introduction
For crane builders and equipment dealers, an electric motorized trolley hoist is the core heart of any single-girder overhead crane, gantry, or jib crane. Importing hoists and trolleys separately from different suppliers often leads to flange width mismatches, unbalanced wheel wear, complex field wiring, and short circuits under tropical coastal humidity.
? The ER Series Solution for clients:
The ALLMAN ER Series eliminates these friction points. We supply a fully pre-wired, factory-calibrated four-direction hoisting and traversing system. By integrating the hoist body and motorized trolley into a single smart control enclosure, ER units reduce your local site installation time by over 50%. Featuring heavy-duty side guide rollers for beam flanges, FEC G80 alloy load chain, Schneider contactors, and custom multi-voltage options (220V-440V 60Hz), the ER series guarantees zero warranty headaches and higher gross margins for your dealership.

Advantages
Integrated Motorized Trolley with Dual-Tread Alloy Wheels
The traversing trolley is equipped with drop-forged, heat-treated alloy steel wheels designed with dual-tread profiles. This allows smooth, low-resistance travel on both tapered I-beams and flat-flange H-beams. Lateral side guide rollers absorb horizontal sway during rapid direction changes, preventing trolley tilting, rail climbing, and flange erosion.
Centralized IP55 Control Box & Quick Aviation Plugs
No more messy external wiring on top of the bridge crane! Both the hoisting motor and trolley motor are pre-wired directly into a single, heavy-duty IP55 weather-tight central junction box. Incoming power and control pendants utilize heavy-duty multi-pin quick-disconnect aviation plugs, preventing water ingress and making replacement or troubleshooting effortless.
Dual-Speed Precision Hoisting & VFD Traversing Options
Hoisting: Features a dual-winding pole-changing motor (4:1 / 6:1 speed ratio) offering both a fast speed for rapid vertical transit and a micro-slow speed for gentle mold placement, CNC machining loading, or glass assembly.
FEC G80 Alloy Load Chain
Surface-Hardened G80 Chain: High-tensile, wear-resistant G80 alloy chain (optional Japanese FEC G80 galvanized chain for high-salt coastal environments like Santos or Valparaiso).
Dual Safety Architecture
Combines an instant-response Electromagnetic Disc Brake that holds rated loads immediately upon power loss with a mechanical Overload Slip Clutch that slips harmlessly if an operator attempts to lift >110% of rated capacity.
FAQ
Q1:Can the lifting height be customized?
A1: Yes. The lifting height and load chain length can be customized according to your application. Please provide the required lifting height when requesting a quotation.
Q2: What is the difference between an electric winch and an electric hoist?
A2: An electric winch is mainly designed for pulling, dragging and lifting applications where flexible installation is required.
An electric hoist is usually designed specifically for vertical lifting with a fixed lifting mechanism.
The best choice depends on your application, load requirements and installation conditions.
Q3: Can the electric chain hoist be used outdoors or in harsh environments?
A3: Yes. Our electric chain hoists can be configured for outdoor, humid or dusty environments. Depending on your working conditions, we can recommend suitable protection levels, anti-corrosion treatments, stainless steel load chains and other optional configurations to improve durability.
Q4: What safety features does your electric chain hoist have?
A4: Our electric chain hoists are designed with multiple safety features, including a reliable electromagnetic brake, high-strength load chain, safety hook with latch, upper and lower limit protection (optional), overload protection (optional), and emergency stop functions to ensure safe lifting operations.
Q5: What information should I provide before requesting a quotation?
A5: To provide an accurate quotation, we recommend sharing the lifting capacity, lifting height, lifting speed, power supply (voltage/frequency), installation type (fixed or trolley), and working environment. The more information you provide, the better we can recommend the right solution.
Q6: Are spare parts and technical support available after purchase?
A6: Yes. We provide long-term spare parts support, including load chains, hooks, brake components, electrical parts and control pendants. Our technical team is also available to provide installation guidance, troubleshooting assistance and maintenance recommendations whenever needed.
