Electric Chain Hoist Guide: DHP Series for 0.5–5T Monorail and Jib Applications
If you are specifying a compact lifting solution for a workstation, assembly bay, or light monorail run, the electric chain hoist is usually the most cost-effective answer. This guide focuses on the DHP series supplied through Chunhua Crane (chinacraneexporter.com), covering capacities from 0.5T to 5T, mounting options, and the duty-rating decisions that determine whether a hoist lasts three years or fifteen.
What the DHP Series Covers
The DHP electric chain hoist is a hook-suspended or trolley-mounted unit built for short-lift, high-frequency work. Standard capacities run 0.5T, 1T, 2T, 3T, and 5T, with lift heights typically 3m to 12m and custom heights available. The hoist is manufactured by Hefei Chunhua Hoisting Machinery Co., Ltd (founded 2003) in the Anhui industrial crane manufacturing belt, and sits in the light-and-small-lifting category alongside the KBK light rail systems, BZD pillar jib cranes, and BX wall-mounted jibs.
Typical configurations:
- Hook suspension — hangs from an existing beam, beam clamp, or crane hook.
- Push trolley — manual travel along an I-beam or KBK rail.
- Electric trolley — powered travel for monorail and jib crane booms.
- Jib mounting — paired with BZD pillar jibs (typically 0.5–5T) or BX wall-mounted jibs for 180°–360° coverage.
Duty Rating: The Specification Most Buyers Get Wrong
Duty rating is expressed under FEM 1.001 / ISO 4301 as a group (1Am, 1Bm, 1Cm, etc.) or under CMAA #70 as a class (A through F). The DHP series is generally offered in light-to-medium duty configurations, but the correct choice depends on your actual cycle, not the hoist's maximum rating.
Practical guidance:
- Under 2 starts/hour, light loads — intermittent duty is acceptable; a standard single-speed unit works.
- 4–8 starts/hour, consistent loads — specify a higher-duty motor and consider a two-speed or inverter-controlled hoist.
- Continuous assembly-line use — do not buy a light-duty chain hoist. Step up to a higher FEM group or move to an LH double-girder or KBK workstation system with a properly rated hoist.
Ask your supplier for the FEM group and the rated starts-per-hour at your load. A 5T hoist rated 1Am will fail quickly in a 6-start-per-hour foundry pattern, while a 2T hoist rated 1Bm may run for a decade in the same application.
Monorail vs. Jib Mounting: Choosing the Right Layout
Monorail
A monorail is a single I-beam or KBK profile running in a straight line. It is the cheapest way to cover a linear workstation — for example, a 12m assembly bay where the hoist travels from a parts rack to a fixture. For monorail work, specify an electric trolley if the operator needs to move loads repeatedly; a push trolley is fine for occasional positioning.
Key checks before ordering:
- Beam size and flange width — the trolley must match the beam, not just the capacity.
- Rail length and end stops — allow for the hoist body plus hook block clearance.
- Power supply — festoon, cable chain, or conductor bar; confirm voltage and control voltage (24V/48V low-voltage control is common for safety).
Jib Crane Mounting
A DHP hoist on a BZD pillar jib or BX wall jib gives circular coverage without a full bridge crane. This is the standard choice for machine-tending, welding cells, and maintenance bays. For a 2T jib with a 4m boom, a 2T DHP hoist with electric trolley is a typical pairing.
Watch the moment load: a jib crane's capacity drops as the boom extends. A 3T jib rated at 3m may only be good for 1.5T at 5m. Always match the hoist capacity to the jib's rated capacity at the actual radius, not the maximum.
Components and Standards
DHP hoists use Q345B/Q235B steel for structural parts and are built to GB/T 3811. On request, units can be supplied to FEM 1.001, DIN 15018, or CMAA #70. Electrical components are sourced from Schneider, Siemens, ABB, or SEW, which matters for spare-part availability in export markets.
Certification options include CE, CCC, EAC (TR CU 010/020), GCC/SASO, SONCAP, and KEBS. If you are importing into Russia, the EAC mark is mandatory; for Nigeria, SONCAP; for Kenya, KEBS. Confirm the certificate scope covers the exact model and capacity before shipment.
Buying Checklist for Export Buyers
- Capacity and lift height — state both, plus hook approach dimensions.
- Duty rating — FEM group or CMAA class, with starts per hour.
- Mounting — hook, push trolley, electric trolley, or jib.
- Travel length and beam/rail size.
- Voltage, phase, frequency, and control voltage.
- Certification required for your port and country.
- Spare parts — chain, hook, contactor, and brake availability.

For a broader view of how chain hoists fit into a complete lifting plan, compare the DHP series against the MD/CD electric wire rope hoists and KBK light rail systems — the right answer depends on whether your priority is headroom, travel distance, or duty cycle.
